Predictors of Small Intestinal Bacterial Overgrowth in Symptomatic Patients Referred for Breath Testing.

Background: Indications for a breath test (BT) are well established in the symptomatic patient with risk factors predisposing them to small intestinal bacterial overgrowth (SIBO). Characteristics and the profile of this population are not well known. Our objective was to study the characteristics of patients undergoing a BT for SIBO and to identify factors associated with a positive BT.
