Small Intestinal Bacterial Overgrowth (“SIBO”) is caused by an overgrowth of the bacteria that we normally see in the large intestine. The problem begins when the small intestine, which normally has very few bacteria, becomes overgrown with gut bacteria. When food passes from the stomach into the small intestine, the bacteria start to quickly ferment the food and produce gas, instead of the normal process of our own enzymes breaking down and absorbing the nutrients.

This gas causes discomfort and damages the lining of the gut, leading to pain and stomach problems.

We have more detailed information on SIBO here…

How do we test?

We test using a three hour breath test analysed by Genova Diagnostics. The test involves drinking a sugary solution then the collection of breath samples to measure both hydrogen and methane. Tests for hydrogen sulphide are not yet available.

Results are reviewed by a Doctor and the appropriate treatment is recommended.

Retesting is essential

Two thirds of SIBO will re-occur if not treated properly and followed up by good maintenance.

It is important to ascertain and address the root cause of the SIBO.

SIBO causes inflammation in the gut, affecting absorption, and sometimes causing leaky gut

Long-term SIBO can cause leaky gut and allow the absorption of unwanted lipopolysaccharides (“LPS”) from gram-negative bacteria.

LPS causes a strong immune reaction and can cause inflammation.

Healing the gut means that nutrients are absorbed properly and LPS is not absorbed.
