SIBO is increasingly recognised as a major cause of IBS. In fact studies have shown that the incidence of SIBO in IBS sufferers could be as high as 84%. But the symptoms are quite similar to other gut disorders. So a SIBO test can be a very reliable way to start to address the condition.
SIBO is caused by an overgrowth of commensal bacteria, which are regular inhabitants of the gut.
Tests for SIBO examine the gases that the small intestine produces to determine if overgrowth is a problem.
