SIBO Test

Doctors commonly use breath testing, such as the glucose breath test or methane-based breath testing, to diagnose SIBO. These tests measure levels of hydrogen, methane, or hydrogen sulfide gas in the breath after the patient consumes a specific sugar solution.

Early signs of SIBO include abdominal pain or discomfort, bloating, gas, diarrhea, and constipation. Some individuals may also experience weight loss and malnutrition.

While professional diagnosis is recommended, a home version of the SIBO breath test is available. It involves drinking a glucose solution and measuring breath gas levels over a few hours, similar to clinical breath tests. Being able to do SIBO breath tests at home allows for easier management of recurring cases.
