Diagnostic Criteria and Algorithm for Common Functional Gastrointestinal Disorders Associated With Abdominal Pain. This algorithm applies the Rome criteria, which are widely used in research studies. Irritable bowel syndrome is defined by abdominal pain accompanied by 2 of these 3 criteria: relief with defecation, altered stool consistency (loose or hard stools), or altered frequency (less or more frequent). The other syndromes are defined by the listed criteria. The criteria also specify the duration and frequency of symptoms, in general, a duration of 6 months and frequency of 2 days every week or more often.
