Bariatric surgery is the most effective treatment for severe obesity. After surgery, patients may complain of gastrointestinal symptoms but their altered anatomy can make investigations difficult to perform or interpret. In particular, the Roux-en-Y gastric bypass (RYGBP) creates an excluded segment that is not easily accessible. We present a case illustrating some of the difficulties encountered when investigating the RYGBP patient complaining of nonspecific GI symptoms. Options are discussed for examining the excluded segment, and the diagnosis and significance of small intestine bacterial overgrowth in the RYGBP patient is reviewed.
