Small Intestinal Bacterial Overgrowth (SIBO) is a serious digestive disturbance which can be treated effectively, but only if it is accurately diagnosed. Typically, small amounts of bacteria are found in the small intestine. Occasionally, additional bacteria migrate from the large intestine or the stomach into the small intestine, creating symptoms such as abdominal pain, bloating, gas, and diarrhea. As the symptoms are very similar to those associated with IBS (Irritable Bowel Syndrome), data from this test may assist physicians in evaluating IBS cases.
Small Intestinal Bacterial Overgrowth can easily be diagnosed by testing patients’ breathsamples for levels of hydrogen, methane, or both. After ingesting a lactulose solution, the patient produces breath samples every 20 minutes over a 3-hour period. Samples are then mailed to the laboratory. Analysis of the samples yields data on production of the targeted gases as the digestive process proceeds. The graph produced using this data provides key indicators of the existence/ extent of SIBO. The graph is a clear and understandable tool that physicians may share with patients in reviewing their test results.
