SIBO Testing

Small Intestinal Bacterial Overgrowth (SIBO) occurs when there is too much bacteria in the small intestine. It is a common underlying cause of Irritable Bowel Syndrome (IBS). Most of our gut bacteria reside in the large intestine and it performs a variety of important roles. A much lower number of bacteria are found in the small intestine. When there is an overgrowth of bacteria in the small intestine, it can interfere with digestion and absorption. As a result, gases such as hydrogen and methane are produced when the bacteria breakdown food entering the intestine from the stomach. This may lead to gastrointestinal symptoms and impaired nutritional uptake. 


The Hydrogen and Methane breath test is used to detect Small Intestinal Bacterial Overgrowth (SIBO). This is a simple and non-invasive investigation. A baseline breath sample is measured by blowing directly into the analyser. Following this, you will be given a testing solution to consume. You will then be called into the clinic room at regular intervals to repeat the breath samples.
All tests are performed with our medical collaborators at The Gastrolife Clinic
