SIBO is a condition in which there is an excess number of bacteria in the small intestine. Usually, the stomach and proximal small bowel contain fairly few bacteria because of the results of the acidity of gastric contents and peristalsis activities. In most cases, SIBO occurs when harmful bacteria migrates from the large intestine to the small intestine and successfully thrives there. Our gut bacteria is responsible for many functions including producing 60 – 80 % of our immune system. Therefore, GI imbalance not only makes ourselves more prone to diseases, but also is linked to more than 40 chronic diseases!
Most common signs and symptoms of SIBO
Symptoms of SIBO include bloating, uncomfortable feeling of fullness, abdominal pain, nausea, diarrhea, malnutrition, fatigue, joint pain, rash, eczema, anxiety, depression, belching, increased gas, constipation, heartburn, and nutritional deficiencies such as B12 and iron. SIBO leads to compromised digestion and absorption of essential nutrients.
SIBO Breath Test
As an example, here we have the results of the SIBO breath test from one of my clients, who I suspected to have SIBO:
Testing for SIBO
Collecting an aspiration sample of small bowel fluid (followed by culture and bacterial count) is considered to be the current gold standard for diagnosis of SIBO; however, it is not routinely performed because it requires a complex, invasive technique, and is costly. As a result, in Functional Medicine, the most accepted test to diagnose SIBO is the SIBO Breath Test.
Treating SIBO
SIBO is not very easy to treat and treatment needs to be targeted to address the root cause of the problem. One of the treatments available include antibiotic combination use. Rifaximin in addition to either Neomycin or Metronidazole, depending upon if SIBO test results show an increase of Hydrogen or Methane would be used. Another option would be Herbal Antibiotics, the most used ones are a combination of garlic, oregano, and berberine for 4-6 weeks. We also recommend that our clients take specific supplements for GI support, in addition to following a Low-FODMAP diet.
Re-testing should be done within 2-3 weeks after completing the treatment. In case of recurrence, another round of antibiotics/herbal antibiotics should be completed. For stubborn cases, after multiple unsuccessful treatments, the Elemental Diet might be an option.
