Companies such as Commonwealth Diagnostics International, Inc. This excessive build-up of bacteria or archaea is often diagnosed as SIBO or IMO. After ingesting a substrate solution, the patient collects breath samples every 15 minutes over a 2-hour and 15-minute (135 minutes) period.ĭuring the hydrogen and methane breath test for SIBO, the presence of elevated levels of hydrogen or methane gas, or both, identified within 90 minutes of ingesting the substrate solution provides evidence of bacteria or archaea in the upper region of the digestive tract (i.e. In a healthy individual, one would not expect to see any hydrogen or methane in the breath samples for approximately 90 minutes – 2 hours, the approximate time it would take for the substrate to travel to the small intestine to the colon where, in a healthy system, the substrate would be fed upon by bacteria, thus releasing the hydrogen and methane gas. The patient will collect a baseline sample, and after drinking the substrate solution, the patient will continue to collect a series of breath samples by simply breathing into a test tube using a straw. Patients are given a substrate solution to drink (lactulose or glucose), which is a mixture of water and a carbohydrate substrate. The hydrogen and methane breath test for SIBO/IMO is a non-invasive diagnostic tool to identify SIBO and can be administered in the comfort of a patient’s own home. In the U.S., some research studies have demonstrated that up to 84% of the IBS population, or 36 million individuals, suffer from SIBO. ![]() Any condition which impairs the normal transit or motion of the small intestine can increase the likelihood of getting SIBO, including lack of adequate stomach acid, damage to the intestine by toxins, or a decrease in the speed at which the small intestine transfers waste to the colon. While bacterium naturally exists throughout the digestive tract, with the highest concentrations of bacteria in the colon, a healthy individual should have relatively low levels of bacteria present in the small intestine. SIBO is the accumulation of an excessive amount of gut bacteria in the small intestine (at least 100,000 bacteria per ml of fluid). However, new guidelines outlining the distinction between each classification have led to the reclassification of methane-related SIBO as Intestinal Methanogen Overgrowth (IMO), since methane in the gastrointestinal tract is produced by archaea, which is not bacteria. SIBO has historically been diagnosed via a hydrogen and methane breath test and either classified as hydrogen-related SIBO or methane-related SIBO. When a patient has SIBO, the digestive system may produce excessive hydrogen and/or methane gas, which can cause many gastrointestinal symptoms such as bloating, diarrhea, cramping, and/or constipation. SIBO is diagnosed when there is an excessive amount of bacteria within the small intestine. In a healthy digestive system, the amount of gut bacteria found within the small intestine is quite low. ![]() ![]() SIBO is an acronym for small intestinal bacterial overgrowth.
