Linking to SIBO. SIBO, or hydrogen disulfide, is a common digestive disorder that can cause a range of digestive symptoms. There are two common bacteria that can induce SIBO: hydrogen-producing bacteria and hydrogen sulfide (H2S)-producing bacteria. A different organism called archaea can create a third type of gas, methane (CH4), which causes a condition called intestinal methenogen overgrowth (IMO).
In a healthy state, the small intestine is a relatively "clean" environment without bacterial colonization. Various protective mechanisms, such as stomach acidity and intestinal motility, help maintain a balanced environment in the small intestine. SIBO occurs when the body's innate protective mechanisms malfunction or when certain medical conditions predispose individuals to bacterial overgrowth in the small intestine.
When SIBO occurs, the bacteria can interfere with normal digestion and absorption and contribute to inflammation of the small intestine lining. The resulting maldigestion, malabsorption, and increased permeability of the small intestine can contribute to the symptoms associated with SIBO.
Hydrogen-predominant SIBO is the overgrowth of bacteria in the small intestine, identified when excessive levels of hydrogen are measured in a diagnostic breath test. Numerous bacteria have been associated with SIBO, including Enterococcus, Escherichia coli, and Klebsiella. Hydrogen-predominant SIBO shares many symptoms with irritable bowel syndrome (IBS).
Hydrogen SIBO occurs when carbohydrate-fermenting bacteria proliferate in the small intestine and generate hydrogen during digestion. Treatment typically includes antibiotics (rifaximin), diet, and sometimes probiotics or supplements. Below is a summary of which foods, probiotics, and supplements have the most scientific evidence.
DETAILED DESCRIPTION OF THE THREE TYPES OF SIBO: HYDROGEN, METHANE, AND HYDROGEN SULFIDE.
https://www.rupahealth.com/post/an-in-depth-overview-of-the-three-types-of-sibo-hydrogen-methane-hydrogen-sulfide (2026).--
1. Recommended Diet for Hydrogen SIBO
Low-FODMAP Diet (most commonly used). FODMAPs are fermentable carbohydrates that feed gut bacteria. Reducing them decreases gas and hydrogen production.
Fermentable carbohydrates increase hydrogen production in the gut, so restricting them can reduce symptoms such as bloating and pain.
Elemental Diet (when SIBO is severe). Predigested nutritional formulas. Used for 2-3 weeks under medical supervision. It has been shown to eradicate SIBO in some patients.

2. Probiotics with evidence.
The use of probiotics in SIBO is controversial. Some studies show improvement, but the evidence is still limited. Strains with more studies:
---Saccharomyces boulardii. Reduces intestinal inflammation. It is not a bacterium (it is yeast), so it does not increase bacterial overgrowth.
----Lactobacillus rhamnosus. May reduce hydrogen in respiratory tests.
----Lactobacillus reuteri
----Bifidobacterium lactis
Some experts recommend against using probiotics during the acute phase because they may worsen symptoms in certain patients.

3. Supplements that may help
---Berberine. Natural antimicrobial. Reduces pathogenic intestinal bacteria. Frequently used as an alternative or complement to antibiotics.
---Oregano oil. Powerful antibacterial.
---Garlic extract (allicin). Especially used in SIBO (Small Intestinal Bacterial Overgrowth).
---Ginger. Improves intestinal motility.
---Digestive enzymes. Help reduce carbohydrate fermentation.
---Betaine HCl. In patients with low gastric acidity, it may reduce bacterial colonization.

https://pmc.ncbi.nlm.nih.gov/articles/PMC11013329/?utm_source=chatgpt.com (2024).-- Integrative protocol used in studies
Phase 1 (4-6 weeks). Low FODMAP diet. Antimicrobials (rifaximin or herbal)
Phase 2. Restore microbiota (selective probiotics)
Phase 3. Improve intestinal motility
Phase 4. Gradually introduce more foods according to tolerance
