Small Intestinal Bacterial Overgrowth (SIBO)

This is a condition in which an abnormally large number of bacteria are present in the small intestine, and the types of bacteria present in the small intestine more closely resemble the bacteria of the colon.


The colon (or large intestine) is rich with bacteria, however, the small intestine generally contains a lot less bacteria comparatively, and there are also different types of bacteria in the small and large intestine.


Ordinarily bacteria travel out of the small intestine with faecal matter into the large intestine. If there are disruptions in intestinal motility or physical disturbance, bacteria begin to accumulate in the small intestine.


SIBO is associated with Irritable Bowel Syndrome and Chronic Fatigue Syndrome. Bacteria overgrowth may break down bile acids, necessary for absorption of fats, thus reducing fat and fat-soluble vitamins (A,D and E) absorption. In severe cases, bacteria may damage the small intestinal wall, which leads to impaired carbohydrate and protein absorption, resulting in malnutrition. Anaemia may also develop when bacteria interfere with B12 absorption.


People with SIBO typically develop symptoms including nausea, bloating and diarrhoea.
