SIBO Breath Testing

What is SIBO breath testing?

Small intestinal bacterial overgrowth (SIBO) happens when too many bacteria grow in the small intestine. It can cause bloating, gas, abdominal discomfort, or diarrhea. A breath test is a simple, painless way to check for it. After you drink a special sugar solution, you breathe into a collection device at set times over a few hours. Bacteria that ferment the sugar release gases such as hydrogen and methane, which show up in your breath. Your doctor uses the results, along with your symptoms, to decide on treatment. There are no needles, and you can usually return to your normal activities afterward.
