The small intestinal bacterial overgrowth (SIBO) hydrogen breath test has had positive results in 84% of patients with irritable bowel syndrome versus 20 % of controls. This research group hypothesized that SIBO would be more prevalent in patients with symptoms consistent with irritable bowel syndrome who have undergone previous abdominal surgery. The group enrolled 77 patients in the study. The conclusion supported the hypothesis and the researchers advised physicians to consider SIBO with patients having GI complaints who have undergone abdominal surgery.
