These gases diffuse into the bloodstream and are exhaled through the lungs. The patient then continues collecting breath samples at timed intervals for the test duration, lasting 2-3 hours.īacteria and archaea in the gastrointestinal (GI) tract ferment carbohydrates, producing hydrogen, methane, and hydrogen sulfide gases. The test begins with the patient collecting a baseline breath sample and drinking a water mixture containing either glucose or lactulose. A SIBO breath test is performed the morning after a patient follows a restrictive preparatory diet and overnight fast. ![]() SIBO breath testing is a noninvasive testing alternative to small intestinal culture to diagnose SIBO and IMO. This article will discuss the SIBO breath tests available to order through Rupa Health. Hydrogen sulfide gas also contributes to SIBO, and recent advancements in testing now allow us to diagnose hydrogen sulfide-SIBO. SIBO breath tests aid in diagnosing and treating SIBO and IMO by measuring hydrogen and methane gases produced by intestinal microorganisms over 2-3 hours. IMO, previously called methane-SIBO, is the overgrowth of methane-producing microorganisms (archaea) in the small or large intestines. ![]() Small intestinal bacterial overgrowth ( SIBO), often used as a blanket term for SIBO and intestinal methanogen overgrowth (IMO), is the accumulation of bacteria in the small intestine.
