SIBO Breath Test

Small intestinal bacterial overgrowth (SIBO) is due to an overgrowth of bacteria not typically found in the small intestine. With SIBO, stagnant food becomes a breeding ground for bacteria, which may produce toxins and interfere with the absorption of nutrients. It is commonly associated with symptoms of abdominal pain/distention, diarrhea, and flatulence. The test for SIBO is a non-invasive breath test that captures exhaled hydrogen (H2) and methane (CH4) gases following ingestion of a lactulose solution to evaluate bacterial overgrowth of the small intestine.
