Hydrogen Sulfide SIBO: What It Is and How to Heal It

Most of us are familiar with having the occasional belly ache or bout of bloating and gas. But what happens when your daily bloating becomes so bad you can hardly button your pants? Or when your abdominal pain gets so bad that it’s hard to even leave the house?

This is the unfortunate reality for those struggling with a serious condition known as small intestinal bacterial overgrowth. 

Today we’re going to dive into exactly what small intestinal bacterial overgrowth is and take a look at a specific form of this condition. We’ll look at how to determine if the bacteria in your gut have gotten out of control, and more importantly, what you can do to treat it.

What Is Small Intestinal Bacterial Overgrowth (SIBO)?

Small intestinal bacterial overgrowth, also known as SIBO, occurs when you have an excessive amount of bacteria living in in your small intestine. You see, your digestive tract is designed to house a host of different microbes that make up what is collectively known as your gut microbiome. 

The majority of these microbes are supposed to reside in your large intestine and colon – where they assist in breaking down nutrients, manufacture certain vitamins, and help your body eliminate waste. But in SIBO, those bacteria begin to make their way into your small intestine – where they colonize and begin reproducing in excessive amounts.

Because your microbiome is made up of trillions of microorganisms of all different kinds, SIBO overgrowth can happen with several types of microorganisms. One kind can be particularly tricky to identify and treat – a specific type of SIBO known as hydrogen sulfide SIBO.

What Exactly Is Hydrogen Sulfide Small Intestinal Bacterial Overgrowth (SIBO)?

The excess bacteria living in your small intestine release gasses. The type of gas they release is specific to the type of bacteria growing in your small intestine. Typically SIBO gasses present as either:¹

• Hydrogen-predominant SIBO
• Methane-predominant SIBO

But there’s a third form of gas that can be emitted by another type of SIBO bacteria – hydrogen sulfide gas. Let’s take a deeper look at exactly what hydrogen sulfide does in your body.

What Does Hydrogen Sulfide Do in the Body?

The presence of hydrogen sulfide gas and the bacteria that emit this gas aren’t necessarily a problem. In fact, hydrogen sulfide serves as an important gasotransmitter – a gaseous molecule that serves as a neurotransmitter.² So, balanced healthy levels of hydrogen sulfide gas actually play a crucial role in the body including:³

• Protecting your cells against harmful agents
• Serving as a potent antioxidant and anti-inflammatory agent
• Modulating your immune response
• Regulating specific immune cells (like macrophages, T-cells, and neutrophils)

But if hydrogen sulfide producing bacteria levels are left unchecked, it can wreak havoc on your gut and overall health. An imbalance in your gut flora and subsequent overproduction of hydrogen sulfide gas can have the opposite effect, causing:³

• Cytotoxicity, or toxic damage to your cells
• Genotoxicity, potential damage to your genetic information within your cells
• Increased local and systemic inflammation
• Destabilization of the protective mucus layer in your digestive tract
• Upregulation of immune activity

So an increase in hydrogen sulfide generating bacteria can spell bad news for your health. Let’s take a look at some of the symptoms and detrimental health effects associated with this overgrowth of bacteria in your small intestine.

What Are the Symptoms of Hydrogen Sulfide SIBO?

Symptoms of SIBO are similar regardless of the exact type of bacteria colonizing your small intestine, and include:⁴

• Abdominal pain or discomfort
• Abdominal distention and bloating
• Excessive gas in the form of flatulence and/or belching
• Diarrhea
• Constipation
• Indigestion and heartburn
• Nausea
• Feelings of fullness or loss of appetite

If left unaddressed, SIBO can lead to more serious complications such as:⁴

• Weight loss
• Vitamin and mineral deficiencies
• Malabsorption 
• Kidney stones
• Weakened bones
• Leaky gut syndrome

So what exactly causes SIBO, and how do you know if you’re at increased risk of developing SIBO?

What Causes SIBO?

While there’s not always one specific factor that directly leads to SIBO, there are several things that can increase your risk of developing an overgrowth of abnormal bacteria in your small intestine such as:^5,6

• Physical abnormalities of your digestive tract: Diverticulosis, Crohn’s disease, scleroderma, adhesions from surgery, history of gastric bypass
• Conditions that can affect the motility of the gut: Diabetes, Lupus, connective tissue disorders
• Certain medications: Antibiotics, proton pump inhibitors, antacids, narcotics, anti-spasm medications
• A weakened immune system: HIV, Immunoglobulin A deficiency, underlying or hidden infections, mold toxicity

While there are a number of things that can make you more susceptible to developing SIBO, sometimes it can be difficult to pinpoint a specific or singular underlying cause. Now let’s look at how exactly SIBO is diagnosed.  

How Is Hydrogen Sulfide SIBO Diagnosed?

The most common and widely used method of detecting and diagnosing SIBO is through a breath test. During a breath test, you’re given a drink containing either glucose or lactulose. Then, over a few hours, you’ll breathe into a balloon so it can be tested for the presence of hydrogen or methane gas.

The problem with the traditional breath test is that previously they’ve unable to detect hydrogen sulfide gas. And unfortunately,in the past that has left us without a 100% reliable way of detecting and diagnosing hydrogen sulfide SIBO.

But the good news is, there is finally an accurate breath test that allows us to get a complete fermented gas profile of your microbiome – including hydrogen sulfide. TrioSmart Breath Test offers a simple and effective way to assess for bacterial overgrowth. Consulting with an experienced Functional and Integrative Medicine Practitioner that can order the test and properly diagnose the results is hands-down the best way to ensure your SIBO is correctly identified and treated. They’ll work with you to determine the root cause of your issues and come up with a comprehensive plan to holistically and effectively address the underlying problem.   

Hydrogen Sulfide SIBO Treatment

While occasionally severe cases of hydrogen dominant SIBO may require a course of antibiotics or antimicrobial herbal supplements, truly eliminating and healing SIBO requires a big-picture approach. Treating and healing SIBO means creating a lifestyle that supports a balanced gut and prioritizes whole-body health such as:

• Eliminating pro-inflammatory foods that promote bacterial overgrowth: Foods that are chock-full of sugar, simple carbs, preservatives, and artificial ingredients can drive up inflammation and are like super fuel to the bacteria that are out of control. 
• Focusing on a well-rounded anti-inflammatory diet: Real, whole foods like fresh veggies and fruits, high-quality protein, and healthy fats are naturally anti-inflammatory and support the balanced growth of beneficial bacteria in your gut.
• Healing your gut: On top of a healthy diet, taking steps to heal your intestinal lining and balance your microbiome are essential. I recommend taking a daily probiotic and incorporating collagen into your daily routine. But there are some additional ways you can show your gut some love – click here to see what they are.
• Balancing your immune system: Your immune system and your gut health are intricately linked. So it’s essential to address your gut health and your immune health simultaneously. Click here to learn some effective ways to boost and support your immune health.
• Prioritizing sleep: Sleep is one of the core pillars of your health (along with diet, exercise, and mindset). So logging adequate hours of high-quality sleep is a critical component of addressing SIBO and healing your gut.
• Incorporating nutraceuticals like Antrantil: Antrantil is a nutraceutical blend of all natural botanicals specifically calibrated to relieve bloating and discomfort caused by excess gas. It addresses the excess gas at the source by specifically attacking and eliminating problem bacteria. You can grab your own bottle of Antrantil by clicking here – you can even get 10% off your first order by clicking here.

Our bodies are not compartmentalized – everything is connected. So truly healing and balancing your gut requires you to take care of your own well-being across the board.
