If you’ve ever experienced a runny nose, sneezing, or watery eyes, then you’ve experienced an allergic reaction. Allergens are bombarding our bodies all the time, and this reaction is a highly protective response by your immune system when mast cells sound the alarm.
Mast cells, also known as “jack of all trades” immune cells, are intricately involved in your body’s allergic response.1 They’re your first line of defense against foreign substances entering your body, and their central role is to protect you. Without them, your body wouldn’t even be able to heal from a wound.2
Mast cells are best known for the role they play in allergic and anaphylactic response. But, studies are revealing that they also play a significant role in immune activation, the development of autoimmunity, and increased inflammation.3
Unfortunately, mast cell disorders and mast cell activation syndrome (MCAS), in particular, are on the rise these days. I believe it’s in part because of the constant barrage of environmental toxins, molds, and chemicals.
Let’s take a look at what exactly mast cell activation syndrome is, how it might be causing your mystery symptoms, and what you can do.
What is Mast Cell Activation Syndrome?
Mast cell activation syndrome is an immune disorder. It’s just one type of mast cell activation disease.
What sets MCAS apart from other mast cell activation diseases is that it isn’t caused by an abnormally large amount of mast cells, and it isn’t a result of pathogen infection. Instead, when you have MCAS, you have a normal amount of mast cells, but they’re overactive and malfunctioning.
When your body is exposed to what it thinks is a threat, these overactive mast cells start to go haywire and secrete massive amounts of chemical mediators stored in the cytoplasm of your cells—degranulation. What’s meant to be a positive, protective response from your mast cells instead triggers both local and systemic negative effects.
When chemical messengers are released into your body, they set off an alarm that triggers an immune system response. And when this response becomes chronic—the chemical messengers are set off too much, too often—the result is mast cell activation syndrome.4
Mast Cell Activation Syndrome and Chemical Mediators
Mast cells are located near the border of just about every tissue in your body because they’re your first line of defense.
Mast cells are especially concentrated in your:
- Skin
- Gastrointestinal tract
- Lungs
- Sinuses
- Nervous system
- Reproductive organs
Because of their close location just below the surface of your tissues, mast cells are readily available to defend against foreign invaders as soon as they enter your body.5
If your immune system is working as it’s designed, it’s able to fight off these foreign invaders effectively. We see problems arise when your immune system goes into a constant state of reaction to allergens. When this happens, your body becomes flooded with histamine and other chemical mediators released by mast cells in response to the allergen.
These mediators include:6
- Histamine
- Tryptase
- Chymase
- Interleukins
- Prostaglandins
- Cytokines
- Chemokine
- Proteases
These chemical mediators are responsible for affecting early phases of allergic reactions. And once these chemical messengers are released into your system, they can trigger even more late-phase and systemic effects.
When you have MCAS, you have repeated episodes of symptoms, although the organ systems that are affected and the combination of symptoms does vary. Let’s take a look at the variety of symptoms caused by overactive mast cells.
What Are the Symptoms of Overactive Mast Cells?
Symptoms associated with MCAS are caused by large amounts of histamine in your body when mast cells become hypersensitive and overactive. I’ve found that even with the huge variation of symptoms that can be present, the number one complaint from my patients with MCAS is often fatigue.
Along with chronic fatigue, here’s a list of symptoms I most commonly see in my practice that cause me to suspect mast cell activation in my patients:7,8,9,10
- Skin-related symptoms of overactive mast cells:
- Hives
- Itching
- Swelling
- Flushing
- Gastrointestinal-related symptoms of overactive mast cells:
- Nausea
- Vomiting
- Diarrhea
- Abdominal cramping
- Bloating
- Cardiovascular-related symptoms of overactive mast cells:
- Low blood pressure
- Rapid pulse
- Passing out
- Vascular permeability (inflammation and swelling)
- Respiratory-related symptoms of overactive mast cells:
- Wheezing
- Shortness of breath
- Cough
- Asthma-like symptoms
- Sinusitis
- Rhinitis
- Increased mucus production
- Brain-related symptoms of overactive mast cells:
- Brain fog
- Anxiety
- Headaches
- Difficulty concentrating
- Sleeplessness
- Neuropathic pain
- Vertigo
What Diseases are Associated with Mast Cell Activation Syndrome?
A growing body of research reveals that mast cells play a key role in the early stages of many diseases. The list I give below is likely not all-inclusive but includes some of the ones that have been identified so far as being associated with MCAS:11,12,13,14,15,16,17
- Allergies
- Asthma
- Atherosclerosis
- Autism
- Autoimmune diseases (Hashimoto’s thyroiditis, systemic lupus, multiple sclerosis, bullous pemphigoid, rheumatoid arthritis)
- Eczema
- Ehlers-Danlos syndrome
- Celiac disease
- Chronic fatigue syndrome
- Chronic inflammatory response syndrome
- Eosinophilic esophagitis
- Fibromyalgia
- Gastroesophageal reflux
- Infertility (mast cells in the endometrium may contribute to endometriosis)
- Interstitial cystitis
- Irritable bowel syndrome
- Migraine headaches
- Mood disorders: anxiety, depression, and insomnia
- Multiple chemical sensitivities
- Postural orthostatic tachycardia syndrome (POTS)
What Triggers Mast Cell Activation Syndrome?
Since 2007, when MCAS was officially recognized, our knowledge about the syndrome has increased significantly.18 But the reality is, even with this new data, we still have a lot of questions about MCAS.
One of them is: exactly what triggers the activation of mast cells and causes them to malfunction in the first place?
A severe flare-up of symptoms might be triggered by pollen in the spring, while a flare-up in the summer might be due to heat and increased exposure to sunlight. Unfortunately, we really can’t be sure exactly what the triggers are when it comes to MCAS. But, the good news is, even with these uncertainties, we do have a basic idea of potential triggers of mast cell activation.
Let’s take a look at some of the triggers that can throw malfunctioning mast cells into overproduction mode:19,20
-
- Medications: narcotics, opioids, NSAIDs, muscle relaxers, supplements, antibiotics, anesthetics, contrast dyes
- Physical stimulation: heat, cold, pressure, pain, trauma, exercise, ultraviolet light, electrical stimuli, osmotic stimuli, friction and vibration, fatigue
- Hormonal: estrogen, progesterone, a-MSH, CRH, emotional stress
- Environmental and allergens: venoms, environmental antigens, pollen, perfumes, chemical odors, natural odors, pet dander, infections, pollution, mold
- Certain foods and beverages: foods and beverages high in histamine (more on this later)
We know that overactive mast cells play a significant role in exacerbating autoimmunity. But the triggers that can cause mast cells to become hypersensitive are vast, as you can see above, and highly variable.
How is Mast Cell Activation Syndrome Diagnosed?
Diagnosing MCAS is difficult in part because we still don’t have a consensus for objective guidelines for a diagnosis. Despite a lack of consensus, a diagnosis of MCAS is sometimes given when a wide variety of signs and symptoms are present without a known trigger and other possible diagnoses have been ruled out.
When a specific trigger can’t be identified and the mast cell activation doesn’t appear to have a known cause, it’s known as idiopathic.21
The first step I take with my patients is to determine if unexplainable symptoms like itching, flushing, gastrointestinal disturbances, systemic hypotension, and fluctuations in blood pressure are better explained by another diagnosis. The next step is to determine if these symptoms can be eliminated through routine treatment.
If symptoms aren’t eliminated, I’ll do a workup to see if there’s a known allergic basis for the symptoms. This allergic basis falls under two categories:
- Primary: activation of mast cells by mutations resulting in an abnormal amount of cells
- Secondary: external triggers like allergic antibodies or infection
If what’s going on doesn’t seem to fit in either the primary or secondary category, and if mast cells are found in a normal amount but are hyperresponsive, then I suspect mast cell activation syndrome.22
When I make a diagnosis of MCAS with my patients, I use this commonly accepted criteria. I look for two or more of the following:23
- Two or more organs that show symptoms of mast cell activation, such as wheezing, flushing, diarrhea, and hives.
- Two episodes with elevated levels of chemical mediators such as 11β-PGF2, serum tryptase, or 24-hour N-methylhistamine.
- At least one episode with serum tryptase consistently greater than 15 ng/ml.
- Primary and secondary disorders, such as systemic mastocytosis or a clonal mast cell disease, have been ruled out with a negative bone marrow and tissue biopsy.
Although not necessarily a criteria for diagnosis, I consider the improvement of symptoms with drugs that target mast cell mediators as more evidence pointing to MCAS.24
Currently, we only know of a few biomarkers that implicate mast cell activation as the root cause of various symptoms and diseases. More research is needed to help us make a more definitive and accurate diagnosis.25
How is Mast Cell Activation Syndrome Treated?
While mast cell activation syndrome isn’t curable, if you’ve been diagnosed with mast cell activation syndrome, you do have treatment options available to help you manage your symptoms.26
Because of the wide range of possible symptoms caused by mast cell activation syndrome, treatment will need to be tailored specifically to you and your symptoms. Thankfully, research studies on effective treatment options for sufferers of mast cell activation syndrome are ongoing.
Antihistamines are typically the first course of treatment I recommend because they target the overwhelming amount of histamine produced by mast cells. I highly recommend Hist Assist to my patients. It’s a very effective antihistamine with a targeted blend of all-natural ingredients that create a powerful combination to promote optimal health and provide you with relief from mast cell activation syndrome symptoms.
For a more comprehensive course of treatment, here are three basic options to help manage your symptoms.
Three Basic Treatment Options
We know that mast cell activation syndrome results from overactive mast cells. So, inhibiting and stabilizing them is an important step in managing your symptoms. There are three basic treatment options that are generally used:27,28,29
Inhibit the production of mediators through the use of:
- Steroids (short term use, ideally)
- Non-steroidal anti-inflammatory drugs
- Immunomodulatory drugs
Inhibit the release of mediators by stabilizing mast cells using:
- Benzodiazepines
- Cromolyn
- Pentosan
- Alpha interferon
- Tyrosine kinase inhibitors
- Ketotifen
- Omalizumab
- Quercetin
Block the release of mediators through:
- H1 and H2 receptor blockers
- Leukotriene antagonists
- Bisphosphonates
Beyond these basic therapy treatments, there are more options available that work by targeting specific symptoms caused by mast cell activation syndrome. For an in-depth look at more treatment options, I’ve listed several effective ones in my article 9 Proven Treatments for Mast Cell Activation Syndrome—Plus, a Surprising Newcomer.
I know that trying to figure out the best medications and supplements to treat your symptoms can be daunting. Not to mention, time-consuming. When you have a lot of options in front of you, it can be hard to know where to start and what’s best. To help reduce overwhelm, I recommend you take a look at your diet as an easy first step.
Becoming familiar with foods high in histamine, so you know what to avoid, is a natural place to start.
High-Histamine Foods to Avoid
Mast cell activation syndrome can make you highly reactive to a wide variety of food. 30 So, avoiding foods that are high in histamine can help you identify foods you’re sensitive to. You might find that you’re able to consume some of the foods restricted on a low-histamine diet and tolerate them well.
I suggest you use the following list as a general guideline and start by eliminating all of these foods in the beginning. Then, you can choose to add certain foods back into your diet. Always be sure to take note of how you feel when you’ve added a food back in, so you can recognize what, if any, symptoms reappear. Keeping a food journal is a great way to do this.
Here’s a list of the top high-histamine foods you’ll want to avoid:31
- Fermented dairy products, such as cheese, kefir, yogurt, buttermilk, and cream cheese
- Fermented vegetables, such as kimchi, sauerkraut, and pickled vegetables
- Fermented soy products and some legumes, such as soybeans, red beans, green peas, sugar snap peas, and sweet peas
- Some fruits, including all citrus, berry, and stone fruits, along with bananas, grapes, pineapples, and over-ripe fruits
- Some vegetables, including avocados, eggplant, spinach, white and sweet potatoes, tomatoes, and over-ripe vegetables
- All shellfish, canned fish, cured meats, and pickled meats, eggs, and fish
- Walnuts and pecans
- All processed oils with preservatives BHA and BHT
- Some herbs and spices, such as cinnamon, clove, anise, curry, cayenne, and nutmeg
- Processed sweeteners and sugar products, chocolate, cocoa, and unpasteurized honey
- Products made with yeast and yeast extracts
- Bleached flour
- All alcohol, teas, fruit drinks, carbonated drinks, and nonalcoholic beers and wines
- All vinegars, ketchup, and mustard (with vinegar), and relish
- All artificial preservatives and food dyes
If you decide to add any food back into your diet, my recommendation is to continue avoiding, or at the very least limiting, all processed foods, artificial preservatives and sweeteners, sugar, dairy, wheat, and restricted spices.
And, as an extra measure to help you control the amount of histamine you consume from food, I recommend Histamine Blocker to my patients. This patented supplement is formulated to help your body combat excessive histamine found in the food you eat.
Where Do You Go From Here?
Mast cell activation syndrome is complicated because it can have both common and unusual symptoms that affect you on a multisystemic level. A doctor who’s familiar with this lesser known syndrome will help take the mystery out of what’s going on in your body. And, the information in this article is an excellent way for you to get started on your path toward healing.
It’s important that you work with a doctor who’s familiar with mast cell activation syndrome and the various ways it shows up.
If you have or suspect you have mast cell activation syndrome, you might feel overwhelmed and uncertain about what you can do to lessen your symptoms and improve your health. Know that most sufferers of mast cell activation syndrome are able to find an effective strategy that works for them and helps them feel significantly better. But, it will take patience, persistence, and an approach that’s made specifically for you and your symptoms.
Now I want to hear from you. Do you suspect you have mast cell activation syndrome or have you already been diagnosed with mast cell activation syndrome? Have you found antihistamines like Hist Assist to be helpful in managing your symptoms? Let me know in the comments!

Dr. Jill-
Your presentation at the CIRS Conference was amazing! You are such a dynamic Physician , educator and healer. I am on moldy house #4. I keep jumping out of the frying pan into the fire. I was treated with CSM 3 years ago when I was exposed to Chaetoneum. Initially, I would sweat profusely upon expose. Then I started having an immediate bowel movement when I was around something I didn’t like ( I have to laugh). Now, I have EMF sensitivity that is causing me to go into seizures. I just moved to a new area and am trying to find Integrative Health Care. Psychiatrists that understand the effects of mold are seemingly impossible to locate. I am a mercury poisoned Dental Hygienist with MarCons and a husband that doesn’t want to move again. I am extremely resilient but I am at the end of my rope. Do you do phone consults? I am the poster child for CIRS and MCAS….
Gratefully,
Kay Helfant
Hi Kay. The EMF issue is most often if not always a Mercury issue, Definitely avoid Smart Meters, Wifi as much as possible esp on Hand Held devices but even being around it at all, and cordless phones (an cells) are all especially bad. I hope you look to safe Chelation, the safest and most effective being the Andy Cutler Chelation Protocol, which unfortunately most Doctors are not using. Good healing to you, sorry you too are poisoned (I am as well as are many others I know personally).
Dear Kay,
I am sorry to hear of your suffering… you might try searching in your zip code for functional medicine trained physicians at http://www.ifm.org. I am not currently taking new patients but you may check back anytime
Warmly
Dr Jill
Hello. My son had an illness 4 years ago that doctors never diagnosed however they speculated he had an undiagnosed case of encephalitis. Since then, he has experienced several ‘flare ups’ of a cognitive fog which eventually leads to insomnia , inability to find words, difficulty communicating and anxiety. He never had these issues prior to his illness four years ago. We cannot find common triggers for when the flare ups happen. His symptoms match many of those you have listed in this article. We’ve been to 18 doctors in all different disciplines given his wide range of symptoms. Wondering if there is a list of doctors who specialize in mast cell activation diagnosis that I can take him to? Thank you!
You might try the world expert, Dr. Lawernce Afrin….
Sounds like Lyme Disease.
lyme can be a trigger to MCAS
Dr. Jill – thank you for your informative article! It’s great to understand the mast cell activation syndrome. My chiropractor found my histamine problem through genetic testing/MethylGenetic Nutrition Analysis, and Professional Health Products Histamine Scavenger solved my problem (I previously had the IgG test to know what foods to avoid). My CFS is gone, my FMS is almost gone and I sleep well for the first time in decades. I love PHP products so much that I became their Colorado rep:)
Hi Angie,
thanks for sharing your story!
warmly
Dr Jill
Hi Jill
I am in France. Do you know of a similar product in Europe to a Histamine scavenger please.
Kindest regards
Janet
Hi Janet,
I believe UmbrellexDAO is from Europe
warmly
Dr Jill
Hi Angie,
What foods did they suggest? I have it in my bladder and can’t figure it out. It’s getting worse. Thank you so much! Debbie
Thank you so very much for this article . I was diagnosed with IBS, dispute having Adhesions removed from my Colon in 2015. Unlike the normal person who has IBS occasionally; I have pain every day. I would like to look into the Mass Cell Activation. I live Las Vegas;. Do you know of any doctors out here who do this?
Hi Jennie
You might try contacting world expert, Dr. Lawrence Afrin, to get a referral in your area
warmly
Dr Jill
Dr. Carnahan, I see you have a great article on Mast Cell Activation and a bit about Histamine Intolerance, for some great help for people that suffer from one or both of these, I would highly recommend http://healinghistamine.com This site has been very helpful to me and many I meet who don’t know much about histamine intolerance. Thanks for addressing this very challenging topic!
Dr Carnahan,
I am reading through the diet recommeded for MCAS by Dr Joneja in the link you give above and there are quite a few surprises on the list so can you comment? My wife follows a different list from Dr Ahern (in addition to strict Paleo) and it seems to help but the list in your link seems strange (why does it allow dairy, gluten and cashews for instance).
I am specifically interested in why the following are restricted:
Sweet potatoes
Berries such as blueberries, blackberries
Grapes
Unpasteurized honey
Thanks for your help!
Dr. Joneja’s diet eliminates foods that contain high histamine levels. The Paleo diet is not focused on histamine levels in food.
warmly
Dr Jill
I don’t know if I just simply have a salicylate and histamine intolerance or if its mast cell activation. I just know that I react to many vegetables , fruits, preservatives,dyes, yeast, fermented things etc. I have completely eliminated gluten products because I was getting brain fog so bad it felt like I got a concussion along with numbness and pins and needles. although putting aside the gluten from food I still get flushing , burning skin, and onset of extreme anxiety. The thing that confuses me if how fast the reaction will come on it will take often less than a minute to start having my skin burn and when I react wrong to a food and get anxiety it happens in less than a minute to and sometimes will last all day so I try to be so careful what I eat. I don’t understand what would be causing me to get such fast reactions from food. Its been hard.
That sounds like a histamine IgE reaction since it occurs very quickly. It could also be sensitivity to oxalates in food or salicylate. I suggest further testing to determine the cause.
warmly
Dr Jill
Dr Carnahan, I love your work. I’m a nutrition consultant that specializes in children with autism. I work a great deal with low salicylate and amine diets, as well as low oxalate. I know salicylates can trigger mast cells, but (based on your comment) can oxalate trigger mast cell activation? Or were you simply suspecting another (unrelated) type of reaction from oxalate?
I suspect that both of these chemicals and the dysbiosis driving them may trigger mast cell activation.
Wow, this article is amazing. I suffered for many years with chemical sensitivities, asthma, allergies & digestive issues. For about 10 years I had even had seizures. Doctors said I had everything from Lymes disease to MS, but nothing was concrete. My husband & I operated a commercial cleaning business for 20yrs. Now he has a lot of the same problems as me. Doctors have been treating him for RADS, asthma & COPD. We found the only way to cope was to be guarded about our environment. We discontinued our business, which helped me to improve, but he continues to decline. Thank you for the research going into understanding this growing problem.
For a more natural approach what do you suggest in supplementations and eating to stabilize the mast cells rather then taking any medicine. Please advise and Thank you!
Hi Judy
I have listed all the natural mast cells stabilizers in article here
Warmly
Dr Jill
Thank you for this article Dr Gill. I saw 2 allergists here in quebec, canada, and have an appointment with a third one soon, since no one helped me, they only do the skin scratch tests to confirm i have pollens, dust, cats and seafoods ige mediated allergies. Now that doesnt help me at all with my mcas symptoms, i evrn had POTS symptoms last summer that fortunatly calmed down since my diet is very stable with testing every safe food separatly ( im eaTing about 30 different foods now). My question is: how do i make sure the allergist does me the good tests to diagnose possible mcas? I cannot travel far to see a specialist, i cannot eat out and im a single mother of two. I do not take any medication. Im afraid to go back to the dentist ( had a cardio respiratory reaction with anesthesiant) . My typical reaction is sensation that something is stuck in my throat. I have much itchiness and redness on the skin. Stomach pain. Thanks for helping me.
Mona, my wife’s story mirrors yours. From the something stuck in the throat, pins and needles, bad dental experience with elevated heart rate for weeks, Benadryl had opposite effect, rashes hives , Ibs, down to potatoes, green beans,eggs, carrots, Haagen Daz vanilla ice cream ONLY. Everything else pretty much causes problems… what foods sit well with you? I gotta get my wife above 95 lbs. thanx:)
Dear Dr. Jill
Do you have ever studied or considered the relation between the MCAS and periodic fever syndrome as PFAPA?
My son has allergies and now it seems he has PFAPA.
Dear Dr. Jill
Do you have ever studied or considered the relation between the MCAS and periodic fever syndrome as PFAPA?
My son has allergies and now it seems he has PFAPA.
It could be related but I have not seen any research on this…
I was not aware that MCAS is related to inflammation my son’s allergies are always related to food and he always had vomits and diarrhea and very specific times rashes. I believe he had FPEIS to rice. We have controlled the trigger foods (no diarrhea or vomits anymore) but he’s still bloated and underweight but growing. One year ago he started with fevers that follow a pattern we are about to get a Periodic fever syndrome diagnosis.
I really wonder if MCAS and PFAPA could be connected and maybe using some of the natural tratement that you mentioned could help.
Btw PFAPA is controled with corticosteroids
ALA is a powerful Mercury chelator and crosses the blood brain barrier. It should only be dosed low, slow and frequently based on its half-life–and only if there are no Mercury fillings in the mouth. Otherwise, one risks redistribution of the Mercury throughout the brain and body.
Hi HC
Yes, ALA must be used with caution but most patients can tolerate low dose R Lipoic Acid

Dr Jill
Hi Dr. Jill,
I have been trying claritin once a day in the morning or Benadryl once in the evening (rather than the claritin) and I am noticing a MAJOR decrease in my night-time pain attacks due to my Crohn’s disease. Since starting the histamine blockers listed above I have been able to stop taking nightly narcotics for the pain. I am also on Stelara so I need to figure out which is causing the breakthrough but the reason I tried this is because I was continuing to have pain despite the stelara. This could be a MAJOR breakthrough for me. I am going to do some experiments where I go off the histamine blockers for a week and see what happens, though I am reluctant to mess with a good thing. Very exciting.
Eve
Wonderful, Eve! I hope this continues to help you…
Dr. Carnahan,
How does one get a diagnosis of MCAS? What specialist is likely to do the diagnosing or order more tests? Immunologist, allergist, dermatologist? My PCP isn’t very open or helpful in discussing other possibilities of all of my vague symptoms. I have always had extreme/severe allergies that cause respiratory symptoms. I am very sensitive in general, to medications and environmental. I have seen an allergist off and on for about 15 years so I do have confirmed allergies. Lately I have “unknown” allergens when I eat and cause nose stuffiness and some facial tingling but no answers as to what is causing it…just that I now need to carry an epi-pen with me. I have a chronic history of: joint swelling/inflammation/stiffness mainly in my hands and back, chronic headaches and 2-3 migraines a month, I bruise extremely easy, insomnia, i flush easily and get hives on my forearms, chronic vit D deficiency, osteopenia, and bone infections in the jaw (4 rounds of antibiotics for that). Starting in 2015 I noticed heart palpitations intermittently after I started antibiotics. they still come and go. Around the same time I started having low blood pressure and have had a few instances of passing out. I was told by my PCP it’s probably just dehydration and to drink plenty of fluids. It’s frustrating to try to piece it all together and get answers. I don’t want to mask symptoms any longer.
MCAS is a clinical diagnosis. Symptoms consistent with MCAS and response to treatment.
warmly
Dr Jill
Hi Dr. Jill,
I am wondering if you have come across joint hypermobility and Ehlers-Danlos syndrome in relation to mast cell disorders? Thought you might want to add it to your list of associated conditions.
This article was just recently published. http://onlinelibrary.wiley.com/doi/10.1002/ajmg.c.31555/full
Thank you for all your great articles!
Chris
I concur with this comment. I stumbled across this article and was surprised to not see EDS listed.
because EDS is a known to be co-morbid with mast cell problems
Love your article & it was recommended by my Rheumatologist. I’m labeled with lots of conditions, Unspecified IBD/IBS, Inflammatory Autoimmune Disorder, Chronic Migraines, CFS, Fibromyalgia & a mental case! Recently diagnoised with Autoimmune Urticaria due to positive Basophilic Activation & a Mast Cell Disorder with extremely high IgE Fc Receptor AB & symptoms. Whatever the label is, it attacks my Skin, GI, Brain, Heart (Electrical) & my joints. I have 2 questions.
1. Can this disorder cause lesions in the white matter of the brain on MRI?
2. Best approach in discussing Mast Cell Disorder with a doctor who is unfamiliar or doesn’t believe the condition exsists?
Thank you for you time & education in these matters!
Hi Lynn,
I do not think MCAS can cause white matter lesions in the brain. Best approach would be to share the resources from Dr. Theoharides and Dr. Afrin
Warmly
Dr Jill
any condition that involves untreated (or under-treated) chronic pain *WILL* cause damage to the white matter of the pre-frontal cortex, resulting in concentration problems and issues with working memory transfer. This is just one of many serious health problems caused by not treating pain.
Lynn,
Read the book “Medical Medium”. I was personally resistant to buying it initially, but it has been a HUGE answer to my medical struggles with autoimmune disease and many other problems (migraines, chronic fatigue, fibromyalgia, Epstein-Barr Virus, etc). Hope it helps you!
Laura
I would say to really consider Lyme disease and co-infections, such as Bartonella, Babesiosis, etc. Lyme disease and its co-infections can cause all of those symptoms, including activate ‘autoimmune disorders’ in susceptible people. Possibly find a good Lyme Literate Medical Doctor (LLMD) or a Lyme Literate Naturopathic Doctor (LLND). Unfortunately, the testing for these pathogens is poor, especially the tests from Quest and Labcorp. A good LLMD or LLND will use other labs, such as iGeneX labs, Galaxy labs, etc. There are other tests too, such as CD75 NK Cells test that seems to be better than most tests to help determine chronic Lyme disease, as well as how well your treatment is progressing. Hope that helps. God bless.
Hi Dr. Jill,
Do you know if mast cell activation can cause fat malabsorption? I had a 24 hour stool test come back positive for fat malabsorption but my stool elestace test was normal and hydrogen breath test was also negative. So it seems like it is not due to pancreatic insufficiency or SIBO. I also had a normal abdominal CT, colonoscopy and endoscopy so they don’t think it is crohn’s or UC. No classic gallbladder symptoms either so they are not sure what is causing the malabsorption. Mainly I have weight loss, diarrhea and left lower abdominal pain. I also have ehlers danlos and possibly pots. Thank you so much for your time! Chris
Histamine affects the gut in various ways, including increased intestinal permeability and inflammation
Dr. Jill,
Father to two year old with EoE. I noticed you mentioned that EoE may be associated to MCAS. I am curious as to your connection of the syndrome and the diseases (eosinophilic types) that typically are reactionary from IL-5, IL-13 and IL-33 proteins. Is it possible that the underlying factor is the CAPN-14 gene or other genes usually associated to a specific organ tract? Or is MCAS associated with another gene and those organs? I have felt that histamines play a big part in EoE but I haven’t seen the scholarly connections between the two (H-1 and EoE).
Hi GMC – there is an association with histamine issues/mast cell disorders and EoE. Check Dr. Theoharides work for possible references..
Warmly
Dr Jill
Hi Dr. Jill,
Thank you for your article. I am wondering if MCAS can be triggered by extreme adrenal fatigue? My daughter suffered with all of the symptoms of MCAS and we were searching for a practitioner to help her with this when we ran across information on severe adrenal fatigue, which has many of the same symptoms as MCAS! Fortunately, treating her adrenal fatigue has stopped the symptoms of MCAS as well! No more daily hives! She is basically having salt daily and nano liposomal Vit C and starting glutathione. It’s amazing how much the salt helps!! So, just curious if there is a connection between these two issues? Thank you!
Hi Madeira,
Yes, fatigue is a common part of MCAS. It can result from many reasons.
warmly
Dr Jill
Is your daughter still free from MCAS symptoms by treating her adrenal fatigue? I keep thinking it’s a case of the chicken and the egg.
Hi Dr. Jill,
Is there a specific probiotic product you would recommend for those with mast cell activation?
Thank you!
Chris
Hi Chris,
There are many things listed and it can be trial and error. One of my favorites is Neuroprotek – call 303-993-7910 if you would like to try it.

Hi Dr Jill,
Quick question, I have lyme and mold (mast cell) and MCS and when I treat either lyme or mold I go into anaphylaxis. How can I get better if the tx causes the immune system to flair so drastically each time?
Thanks for your time,
Lexi
Hi Lexi
You may need to work on gentle detox before your body can handle treatment
warmly
Dr Jill
What would you consider as a gentle detox? Sweating? Oil pulling?
Thank you so much for your response!
Epsom Salt baths, herbs specifically that help with detox. Check out Burbur-Pinella Detox (tincture) from NutraMedix. There’s also Red Root, Milk Thistle, etc. Just be careful by going slow and adding only one supplement at a time, maybe take it a a very low dose and build your way up as tolerated (it may take you weeks). Then, possibly add the next supplement. There are a lot of ways to gently detox. You may want to find a good Naturopathic Physician in your area.
I am the only one in my family that can’t handle the side effects of Synthroid. I get jitters, balance problems, and dizziness. I used to be on antidepressant but since I been off of them, all these symptoms happened. Still suffering almost 4 years now. I wake up with jitters, then it subsides when I get up. I take Synthroid, then Lorazepam, wait an hour, eat breakfast and take Lisinopril (bp meds). The BP meds stops my heart racing and blood pressure going up from the Synthroid and the Lorazepam stops the jitters. When I wake up in the morning the BP meds and Lorazepam worn off and very bad jitters in the am. I got thru this cycle everyday. I feel the Synthroid causes my balance problem because back in 2007 I was on 150 Synthroid, was too high so they lowered and was fine, but was on antidepressant. The BP meds causes me dizzies cuz I never was on them in 2007, just had balance problems with no dizzies. Today for the past 3-4 years both dizzies and balance problem. I hardly go out and need to stay on very low sodium diet to get less dizzy. If my BP reaches 105/65 and over, the dizzies get bad. Before ever on BP meds I used to be 120/70 with no problem. Now it feels like high blood pressure. I hate BP beds, makes me worse. I need help so bad, I don’t know what to do. My psychiatrist wanted me to try Zoloft but scared cuz of possible hallucinations (not one of the common side effects, but I fear it) and dizziness where I have dizzies already. I don’t know what to do. Why can’t I handle Synthroid? 🙁
HI Josy
Everyone is different and you may be sensitive or allergic to excipients in the Synthroid. You might try a glandular thyroid product, like Armour or Naturthroid or a clean version of T4, like Tirosint.
warmly
Dr Jill
Very helpful and informative article, but I am stumped as to why the only options listed for insomnia ( both onset and sleep maintenance) are benzos. No other effective options?
I recommend Kavinace or Kavinace UltraPM
Also Mast cell is associated with Ehlers Danlos Syndrome, or EDS
yes there may be an association
The route cause of most of these symptoms and syndromes 61 different strains of the Epstein-barr virus and 15 different strains of the non rash shingles virus. Medical science and Medcal Research cannot test for almost all of these 90 different strains and they are all viral infections. They are the underlining cause of Lyme Disease as well. Google author Anthony William and his book Medical Medium released in November of 2015. Lyme is not bacterial is an incredible claim to make and the detail in which the statement is presented in the book will unnerve those in the Lyme community because they traveled down the wrong road for the last 40 years.
I agree with this 100%! I am reading his book now!
Hi Dr Jill
I suffered an anaphylactic reaction to contrast media and iodine that messed me up. I was perfectly healthy before this and now got so many symptoms excersize intolerance, digestive issues, skin changes, loss of collagen in hands feet, it even gave me a dvt in the leg. I was so healthy before this and I marked off I was allergic to hey when I went for the cat scan. Can you reccomend what type of specialist i might want to see.to get tested. This happened to me four months ago in my home. It was a delayed reaction and it happend like three nights in a row i had no idea what was happening to me. I appreciate suggestions you can give me
Mike
Hi Michael,
You might try an allergist or immunologist who treats MCAS. If you are in Colorado you can try ImmunoE health

Dr Jill
Hi Michael,
I had a CT scan with dye contrast and delayed reaction in December 2016 and have since suffered greatly from all the symptoms you mentioned. The worst being the burning skin and anxiety. I am trying to find a doctor to help me. I hope we get help. This is not humane all the suffering.

Hi JoAnne,

I too had a contrast dye reaction (10 hours after the scan) of intense flushing, itching and burning – it has been 4 months and I am still almost constantly reacting, have lost so many foods, trying different MCAS treatments but still struggling to find the right dose and blend. I am seeing Dr. Afrin so hopefully will get answers. But the triggering of the CT contrast dye is absolutely what kicked off this bad flare.
Hello Dr. Jill,
I am new to this. My 4 year old has been having reactions that have increased over time: flushed skin, all over itching, cough, dark circles under eyes, joint pain, constant stomach aches, irritability…etc.. She has been allergy tested for specific foods, molds, pollen, etc. All negative. Yesterday, her allergist discussed MCAS as the probable issue we are encountering. Our next steps are to monitor and observe the foods she is eating and find the triggers and avoid them. (including activity and stress or frustration triggered symptoms have been observed.) In the mean time she is to take Zyrtec daily or Claritin, (this does not seem to make a difference.) and stop back in 6 months.
I would like help in deciding what our next steps should be? What type of specialist(s) should I reach out to? I would like some more secure answers and treatment. I want confirmation that this is indeed what we are dealing with. I want consistent effort in her care. I want alternative options for diagnosis and treatment. I need some more support and resources. I am not confident in our current healthcare providers do to their lack of urgency for such a young girl to be experiencing MCAS. What can I expect for her/us? will it continue to get worse? Is this precursor to something more?
Your article and responses to others’ inquiring have so far provided me with more awareness on MCAS.
Thank you,
Amanda
A very concerned Mother
Hi Amanda
You are best finding an immunologist or allergies familiar with MCAS. If you don’t have any luck, try a functional medicine doc.

hi! just thought id add that POTS is actually postural orthostatic tachycardia syndrome NOT postural orthostatic hypotension 🙂
Thanks, Sophie! Just edited 😉
Thats alright! i’ve been having many of these issues myself for the past year. i can break out in rashes on my chest and or face and sometimes arms,i never know why. but recently i’ve realised i normally have face rashes,my resting hr is high of 120-125bpm,which flares my POTS symptoms. I feel nauseous,dizzy,the rashes can be itchy sometimes,i have IBS aswell and its normally after i’ve eaten food and weirdly enough,does not always happen the same way or always with the same food. I reacted to some food additives one day i believe and then a few days later i had something to eat with the same food additives and i didn’t have a reaction to that food. there are some things i’ll react too continuously eg. alcohol and such and alot of foods,such as apples. but some times,its really a mix and match of what i might react to that day. I’ve always had that though,just lately noticed the rashes and the tachy resting heart rate and very sick feeling all happen when ive eaten something my body decided not to agree with and even suffer with chronic reacurrent utis (looking into IC perhaps soon as we cant find a reason for it to be happening)
My question is,i’ve always developed intolerences to things/allergies after a few months of eating/using them and then i always get continously sick if i have them after this has happened. then i wait a few months i try the same food again and then sometimes i can be completely fine or get very sick.
I’ve been considering looking into Mast Cell but always thought that you have to react to something each time,is this what happens? or can it be just completely random luck?
Dr. Jill,
Someone mentioned to me that my 7 year old daughter’s “sun allergy” may be due to MCAS. I looked it up and found your article. We have been dealing with eczema issues already for mainly the past few years. We are working with our integrative pediatric practice to try and figure out her root cause. She just had blood drawn for the ALCAT this week. I have always questioned mold. How can we know if our house has mold or even her school? Can you give me anymore information on this sun allergy? This just started in October this year at the same time she was taking some homeopathic metals drops from a Functional Dr we were seeing. Thank you so much for your help!
Hi Jamie – Solar urticaria may be a sign of another autoimmune disease, like lupus. I suggest finding an integrative or functional medicine expert to help check her gut and nutritional status and screen for autoimmune disease.

Hi I’ve stubbled across your paper on a bid to try and work out my symptoms and the fact that my body seems to be on self district ‘re reactions. I first started with latex reactions after dentist visits as a child. By my teen age yrs this was blisters and swelling. This in years since has lead to reactions to fruit mainly and some spices. In the last 2 years I now after a major rection to the dentist environment children being treated. They gave me a anti histamine which I also reacted to. I’m now left that I react going into hospitals and have fits
Direct activation of mast cells by which of these :
drugs or food ? And why?
Thanks in advance.
by both drugs and foods and hormones and toxins and many other insults
I have suffered with Spontaneous (Idiopathic) Angioedema and Urticaria for more than 8 years. Facial swelling to the point of disfigurement and hives on my torso the size of dinner plates. I was tested for Hereditary Angiodema with results being negative. I was put on a regimen of Hydroxizine, Allegra and Zymetadine. While heavily drugged, I still had occasions of hives and facial or extremity swelling.
I was put on injections of Xolair every 4 weeks (150 ml) and haven’t had any symptoms for more than 8 months.
Anything else new for treatments?
Hi Mary, unfortunately mast cell issues may be trial and error of what may help… keep trying, don’t give up
We sound the same, I have had chronic hives going on 5 years and have been on Xolair for 3 or 4 years now. I also get two 150mg shots every 4 wks. It was a life saver for me as all the multiple other meds I was on at one time stopped working. I went to the ER covered head to toe in hives with trouble breathing. Epi and steriods did nothing, where in the past they worked. The ER then sent me away since they didn’t know what to do (scary situation) and told me to go see my regular doctor. I was super close to driving to MAYO clinic that day. Luckily I was referring to a dermatologist who had one 150mg of Xolair and asked me if I wanted to try it (he had not given it to a patient before), I was desperate at this point and told him to go for it. Within 4 hours in was completely clear of hives.
Dr. Jill,
I researched MCAS at the recommendation of a physician friend. I told her that my allergy symptoms have improved significantly with Zantac, Xyzal, and a Pulmicort nasal rinse in just one month. This is the first December in sone years that I haven’t had a sinus infection the entire month. Not to mention I have suffered throughout the entire year. Do you have any specific insight about repeated sinus infections? Thank you!
Hi Melissa,
Yes, the diagnosis of MCAS is made based on clinical symptoms of mast cell activation and response to treatment. So it is quite likely that your symptoms are in some way related to mast cell activation.
Warmly
Dr Jill
I have had over a dozen anaphylaxis episodes, 4 that have ended in intubation, and am on continuous infusion Benadryl using a CADD pump. My specialist has left MN and I am having a very, very hard time finding someone to accept me as a patient, is there any chance you have a recommendation for the state of MN.
Hi Beverly,
you might try Dr. Lawrence Afrin or Dr.Theo Theoharides for MCAS experts.

Hi Jill
I’m reacting to everything, even things I was fine with a month ago. I’m trying to start H2 blockers but I’m even having difficulty with that. Any ideas what I can do?
Many patients with MCAS must get compounded cleaner version of the H1 and H2 blockers or Ketotifen
Dr. Jill
I’m wondering if this might be my.problem. I have had chronic hives for going on 5 years with no reason why. I’ve taken a multitude of meds to control them..including 2 years of steroids mixed with other meds, finally they have me on Xolair, two shots once a month to control, although I still have break through hives. Could Mast Cell be the cause of this. I’ve had a partial knee replacement at 36 (March 2017), we were thinking due to the extended use of steroids (broke down cartilage). I also have a multitude of other weird issue. And I need to find out what is wrong with me… Thank you
Hello, Thank you so much for your article on MCAS. I have been trying to get symptoms under control for awhile. Wondering about palpitations. They were not mentioned here, but I have read in other places palpitations are common in MCAS. I have had many heart test and have been told by the cardiologist he is not concerned as there is nothing wrong with my heart. Wondering about treatment for palpitations that worsen when eating or very hungry. PPI’s make the most difference – symptoms much less severe, but do not elevate them completely. Oral ketotifen (1mg twice per day) helped the first few days, but then stopped.
Palpitations are not uncommon in MCAS…
Dr. Carnahan,
Thank you so much for the information that you’ve provided. Is premenstrual dysphoric disorder (PMDD) also tied in with MCAS?
Mast cell issues can certainly contribute to dysmenorrhea, menorrhagia and PMDD…
Hi Mel,
Mast cell disorders may be associated with menorrhagia, dysmenorrhea and PMDD
warmly
Dr Jill
Have gone in circles with rheumatologist and family doc. Knees get watery, pain, unable to walk in a flare up. Thought dysautonomia was the culprit. Also started histamine blockers. Went to DNA expert. Told they could test for that but not treat, went, was told hearsay of my genetics and possibilities and testing was waived. Seen there is a DNA test for MCAD. Kinda sore the experts railroaded me, presumably to set an example for going over the family crackpot. Any feedback is good. Jill. Thank You… Robert in ILL.
Hi Jill,
Love your article and can’t wait to show it to my hematologist and PCP. I just had a bone marrow biopsy and it was normal as I suspected. I have been diagnosed with multiple things that are on your list. I don’t get hives or a rash but I get this awful burning sensation from head to toe followed by nausea, vomiting, diarrhea, and horrible sharp pain in my abdomen. Sometimes I get a headache. I have been on Zyrtec and montelukast for several years. Started having major flares starting last fall that kept sending me to the ER. I had stomach surgery in November due to failed nissen fundoplication which was undone and a Linx device was put around my esophagus. Since then I have only had one major flare and I think fewer flares is due to not being able to eat very much. After this last flare a week ago I added Zantac 150 mg BID and it is helping tremendously. I still get some burning sensations and stomach cramping with diarrhea but it has improved. I have experienced anaphylaxis 3 times, 2 to medications and once to CT dye. I am trying to convince my doctors that I have MCAS but since my biopsy was normal they say there is nothing wrong with my mast cells. Where I live in Colorado there are no specialists that I am aware of. Do you know of anyone on the western slope who treats mcas? Thank you so much. Cindy
Isn’t ondansetron primarily for nausea? You have it listed under diarrhea.
Yes, it can be used for both
Hello Dr Jill- Great article! Do you see geographic tongue regularly in your patients with mast cell/candida/mold/Lyme? many people have this condition and it will flare every time there is a histamine release but I do not believe histamine alone is the cause it just makes it worse. Curious if you were able to successfully address this and if you could please share what has worked I would be grateful. many thanks!
Niteen
Hi Niteen – find and treat underlying food sensitivities, nutritional deficiencies, and toxic exposure, dysbiosis, etc
Dear Dr. Jill
Thanks for a great article!
I wonder if U have ever heard of Familial Mediterranean Fever? I take colchicine for it and thought I had figured out my life long periods of illness but then stumbled upon histamine intolerance and MCAS etc….. both of these “diseases” have many of the same triggers and share so much in common I believe they are connected somehow but cannot find any medical references to support my theory. Just wondering if U had any thoughts?
Thanks so much
Kat
Hi Kat,
Yes, Indeed, I have heard of FMF and it can be associated with MCAS, you are correct

Good afternoon my daughter has all the symptoms allergist thinks she might have MCAS she’s been in and out of the hospital getting worst doctors at the hospital says it’s mental becasuse when she’s having the attack high blood pressure instead of low blood pressure. What’s your opinion.
You may need to consult with an expert in MCAS
Hi Dr Jill,
Thanks for the detailed article!
If I were to lessen my toxic load (Mold, Virus and Candida) could my mast cell issue go away?
I have the same question?
Thanks

Yes, decreasing the triggers to mast cell activation may help!
Hi! Thank you so much for this article. I have Endometriosis and chronic fatigue alone with migraines and chronicle inflamed sinus glands. All diagnosied. I have a history of hives, skin irritation (now rosacea), sensitivity to foods, abdominal pain, swelling, itching, and heart “flutters”. I have seen specialist for almost everything but now would love to talk to someone more about Mask cell disorder. It was something that was brought to my attention in an Endometriosis Group. I live near Seattle and would like to make sure I am seeing a dr who knows what they are talking about. I have had 8 surgeries in the last 4 years and am exhausted and want to feel better. Any suggestions of a great dr in my area? Thank you so much!

Dear Dr. Carnahan:
Thank you so much for all the information and insight you provide in this article. I have a particular question to ask you in regards to heparin testing, being one of a very sensitive and specific markers of mast cell activation.
Laboratories that perform heparin testing, usually do Anti-Xa assay. However, they would like to know, if there is a need to measure fractionated vs unfractionated heparin (UFH vs LMWH). Which assay is most appropriate and relevant for MCAS/MCAD diagnosis?
Thank you in advance.
Where do you go to request this kind of testing?I saw a Primary care doctor recently that suspected I had histamine intolerance but didn’t offer any testing or treatment.I seem to have chronic health problems but with no answers to what the cause is. Do I bring this up to my new primary care doctor?I am on Medicaid and they don’t want to do much testing to keep costs down.I have complained about many of the symptoms that are on your list for the syndrome,but my doctor likes to shrug them off.
Hi Jennifer – many can be drawn through LabCorp or Quest Diagnostics or Mayo clinic but I don’t know of any one lab that does all of the testing
warmly
DR Jill
Hello Dr. Carnahan,
So I am not going to bombard you with my medical history, clearly the fact that I am reading your article already tells you that I am having some issues, I am seeing a functional doctor but they are not the most informed in my case. I have a few questions that I would really appreciate you answering for me.
1) Lets say you have a new patient that can’t afford functional testing, what testing would you recommend the patient do that insurance will cover to get the ball rolling?
2) The same patient has tested positive for SIBO, IGM Positive for Yeast. This patient is sensitive to histamine at the moment. What would recommend testing with first as far as treatment is concerned?
3)Going back to question 1, what bugs should be tested for as well with the same financial restriction?
MCAS is a clinical diagnosis, testing is only a small piece of the picture
Hello Dr. Jill,
I would like to share our 15 yr old daughter’s story in the hopes of finding answers of some kind. She is on state insurance (CHIP) here in PA and I am not able to afford taking her to a specialist out of state. Our daughter, Adie, became ill last December (2017) with two weeks of what they thought was the flu (and treated it as such). She remained ill through January and into Feb, off and on. In late Feb. she got so sick that I took her to the ER where they thought she has mono, but it was negative. Her liver numbers were slightly elevated and her neutrophils were too low so they admitted her to Penn State Hershey Children’s Hospital. She remained there for three weeks. Over the course of those three weeks she had episodes/flareups that included red, flat rash on her cheeks (and upper arms and inner thighs), hot/cold flashes, fevers (anywhere from 99 to 105 at one point) accompanied by cold feet, weakness, dizziness, dry and harsh cough, sore throat, headache, abdominal pain, diarrhea, joint pain (all over but most severe in hands), swelling of face (especially around eyes), pain in eyes, shakiness, brain fog and more that I am probably forgetting.
She was seen by every pediatric department , including infectious disease and they ran test after test and couldn’t come to any conclusions. Her WBC was low, sporadically, too. After three weeks, they had no answers and she “seemed” better so they sent us home. We continued seeing infectious disease until her neutrophils went to low normal and they discharged her from the Hershey drs. in June.
Since June she has had episodes/flareups/crashes off and on. She often looks extremely pale and needs to sleep a lot. The rash on her cheeks comes and goes as does the puffiness in her face. She continues to have joint pain, as well. Over the last three weeks she has been having these episodes quite often and I finally took her to our pediatrician last week. She had us get blood work and it shows low hemoglobin, low ferritin and low IGA Antibodies. She ordered a Celiac Biopsy and that is scheduled for Nov. 7 as well as an immunology appt (both at Hershey). Other than that, she said our daughter is a mystery and to get rest and drink plenty of water.
On Saturday night, we were at my SIL’s birthday party (lots of food) and on the way home our daughter crashed in the car. By the time we got home she could not walk and was having a full blown one of these episodes. She was crying and crying that she just wants to be well again and not be sick anymore. Her face was twice it’s size, the rash was back and all the other symptoms that come with it. She fell asleep and when she woke up Sunday morning she still felt terrible. She went back to bed and slept all day. I took her to Hershey ER and they checked her for dehydration (she wasn’t), did a simple physical, told us that bloodwork was just done last week (CBC) and that they didn’t think they needed to do it again and sent us home.
Please help us. I suspect that this might even be familial as I am 43 and have suffered from joint pain, migraines, depression and anxiety (both of which my daughter has), severe nightly itching (all over– like a burning, intense itch), severe allergies (watery eyes, cough, sore throat) year round, chronic sinusitis and chronic bronchitis, fatigue, weakness, etc, for YEARS. I have had drs argue whether or not I have fibromyalgia but have never found relief or help and I usually just take Benedryl and pain relievers to try and help.
More than myself, I just want our daughter to be well. I feel like drs are telling her this is all in her head now and that she “looks ok” so she must be. I feel like because they haven’t found anything they are giving up looking at all. She has given up so many of her favorite activites and she homeschools now because she never knows when an episode will hit or how long it will occur. She desperately wants to be a normal kid again.
We are a low income family and she has state insurance (CHIP) which limits us to who we may see for treatment. I just don’t know what to do anymore. Thank you so much for your time and for your website.
Sincerely,
Ann Marie Miller

Hi Ann- so sorry to hear about all that you have gone through with your daughters health. I suggest searching for a functional medicine doctor near you to help – http://www.functionalmedicine.org.

Dr. Jill
Dr. Jill,
The only period of time in my life that I experienced severe mast cell disorder symptoms was from early 2013 through early 2018. The worst sympyoms were large wheals on my feet, ankles, legs, wrists, and buttocks; also, severe brain fog and feeling drowsy all day despite good sleep at night. There were other symptoms, as well.
Through trial and error “sleuthing”, I found out what the causes were, and was able to eliminate the MCAS-type symptoms.
1) Excess oxalate deposition in soft tissues and bone, throughout my body. It happened in part due to leaky gut caused by….
2) Intestinal parasites!
3) I also found out, through detailed testing, that I was severely hypothyroid!
4) Severe, long-term hypothyroidism also had a deleterious effect on my adrenals.
5) Also, post-infection SIBO was part of the problem.
By dosing the right kind of thyroid meds, going on a low oxalate diet, using adrenal cortex supplements, most of the MAST cell symptoms went away. Now, I am addressing the parasite and SIBO issue.
It takes testing and detective work; but the root causes of disease can be discovered and fixed.
I am on h1 and h2 blockers and that helps me a lot. But I still produce too much stomach acid probably from chloride issues in food.
Can you combine h1 and 2 with proton pump inhibitors or should you use one or the other?
Imam sure of not having too little stomach acid as I tested with HCL which made my chloride food problems even worse.
I produce a lot of mucus, coming from the nose when my chloride level up and anything that increases stomach acid gives me trouble and makes my hair fall out instantly. ( also tapwater)
Yes, you may combine H1 and H2 blockers
My question was of I can combine h1, 2 AND proton pump inhibitors
I already combine h1 and 2 but my stomach I react on everything that has chloride in it ( so that woild be all food practically)
So can I combi levocetrizine ranitidine AND omeprazol?
TIA
Yes, you may combine all three if symptoms are severe. Best to speak with your doctor about dosing…
Hi Dr. Jill!
I’m just now coming across this whole mast cell world. My symptoms seemed to have started when I was pregnant with my third child. (This is what sent me on the research path.) but now that I look back, I can see other times in my life that some of these symptoms may have existed…mainly anxiety, random hives, GERD.
During my pregnancy, I started developing strange attacks after eating. My heart would start racing, i would get flushed, dizzy, and my anxiety would shoot through the roof. I would also get heart palpitations. I went to the ER twice. Everything was fine except both times my potassium was low.
I am 3 mo postpartum, and I have seemed to have developed food allergies or sensitivities. I seem to react to everything quite honestly. Mostly I just itch after eating with some asthma like symptoms. I’ve put myself on a low histamine diet, and not only am I not consuming the amount of calories needed to support breastfeeding, I feel like it’s just not working.
I don’t know where to start. I suspect I could have SIBO too. But everything is so closely matching. My husband was treated for Lymes years ago. The house we live in now did have mold that was removed. I have had more than my fair share of emotional trauma within the last year, AND I am post partum. I am a basket full of possible root causes.
My main questions…what do I treat first?
Of the main natural treatments, what are those safe for breastfeeding mothers?
Probably best to find a good functional medicine doctor who will check for infections, toxic load and activation of mast cells and treat these issues. I suspect the mold exposure was a trigger to your current symptoms.
warmly
Dr Jill
Dr. Jill,
I have “bouts” that happen without warning, usually after eating where my hands start to itch, skin gets hot/flushing, and almost immediately after is simultaneous vomiting and diarrhea, and a feeling like I am going to pass out. It is happening more frequently and getting worse. The most recent event was earlier this month and I was so dizzy I couldn’t even walk. I had to lay in bed and was even finding it hard to breathe. This started about 22 years ago during my college years and would happen once every other year or so but now it happens several times a year. This year alone, I’ve had it happen three consecutive months in a row. I have noticed that terrible anxiety can also be a pre-curser. The last time it happened I literally thought I was going to die.
What do you think this is? What should I do?
Dr. Jill,
Are you aware that many of the drugs you suggest for MCAS: Either block DAO, HNMT, or liberate histamine eventually leading to Histamine Intolerance and eventually MCAS?
I would love to hear your thoughts!
Thank you
Hi Jon
There is certainly no perfect options but some symptoms are severe enough that drugs are appropriate to control symptoms.
Warmly
Dr. Jill
Hi Dr. Jill,
I’m trying to decide if it is worth looking into MCAS for my digestive problems or not. When they flare up I have lots of digestive problems, fatigue, tingling hands/feet, low iron, migraines, joint pain, muscle pain, raynaud’s, sinus problems, and all over itching. But I don’t normally have a rash! (I have occasionally in the past, but it isn’t hives). It’s just this odd sensation of itchiness across my entire body. I’ve eliminated all of the foods that I know of that trigger symptoms, and that has greatly reduced my symptoms. But I still commonly have GERD, occasional diarrhea, sometimes fatigue, and some joint aches. And I feel like I have this low(er) level problem that I just can’t solve. Does this sound like it could be related even though I don’t really get hives?
thanks!
yes, this is possible… you may try some of the testing listed or see if antihistamines relieve your symptoms
Thank you for this information! My son, who is 28 has had GI issues for some time. He’s doing better now but he has to take Creon as he does not produce enough pancreatic enzymes. He gets hives pretty much every day. At first we thought it all came from Lyme some years ago but he was treated for Lyme. Then we came across some information about long term side effects from the acne drug Accutane. We think it may have more to do with that. My question is, he currently is taking something called Antronex by Standard Process which is yakriton that a NP doctor prescribed. He also takes D-Hist by Ortho Molecular. I saw you liked Umbrellux. Is this a better fit for hives? Do you know about Antronex for histamine? I still believe there is a connection between his GI symptoms, the pancreas and the hives and that he can be healed. He has improved with eating a very clean diet and lots of various supplements. I just know from reading about histamine that it’s not good for his gut. I would be curious if there’s a better supplement for the hives. Know anyone great in New York City? We’ve been though a few trying to find someone smarter and more dedicated.
Hi Alisa
For hives or allergic symptoms, I prefer Thorne Quercenase or NeuroProtek
Warmly

my daughter was diagnosed with a solitary mastocytoma when she was 6. She has had issues right along with NSAIDs causing full body rash. as a teen, she started having issues with peanut butter causing a huge gi flare and urgent bowel evacuation. She has since developed rashes with other foods. Her whole life eating has caused facial flushing, which has gotten worse. She has been on antihistamine and took herself off 7 months ago. since this time all of her reactions are worse and now she is experiencing headaches, fatigue, flushing, achy body, depression, and anxiety. First of all, can a solitary mastocytoma turn into mast cell activation syndrome? or what else could it be? (her father was diagnosed with MCAS 5 years ago) Second, do those symptoms seem like they point to a mast cell issue? Her ANA was high, but every other test to point towards autoimmune was negative. We are in an MCAS ignorant state and we need to figure out the direction to go. Her new primary care is willing to learn and help us, I just am not sure if this is the right direction to look. Any insights would be appreciated.
