Rome IV Diagnostic Criteria for Functional Abdominal Bloating/Distension

Description

Evaluates the Rome IV criteria for diagnosing Functional Abdominal Bloating/Distension. Diagnosis requires recurrent bloating and/or distension occurring at least 1 day/week, which predominates over other symptoms, in the absence of criteria for IBS, functional constipation, functional diarrhea, or postprandial distress syndrome. Symptoms must have started at least 6 months ago and been active for the last 3 months.
