A test frequently ordered by physicians is the hydrogen breath test for small intestinal bacterial overgrowth (SIBO.) Researchers studying digestive disorders have determined that a large number of patients suffering from abdominal pain, bloating, diarrhea, etc., were found to have this disorder. Bacteria that are normally found in the large intestine had migrated into the small intestine. There appears to be a strong correlation between SIBO and IBS. Once diagnosed, and treated with an appropriate protocol of antibiotics, these patients have experienced welcome relief from their symptoms. Similarly, accurate diagnosis of one or more of the sugar intolerances by using one of our breath test kits, can lead to development of a treatment plan that can greatly diminish painful digestive reactions to lactose, fructose, or sucrose.
