Irritable bowel syndrome (IBS) is characterized by recurrent abdominal pain or discomfort that has occurred at least 3 days per month in the 3 months prior to diagnosis. One of the subtypes of this disorder is IBS with constipation (IBS-C), where individuals experience hard or lumpy stools at least 25% of the time and loose or watery stools less than 25% of the time with defecation. This review addresses IBS-C, detailing the epidemiology, etiology, pathophysiology and pathogenesis, diagnosis, differential diagnosis, treatment, and prognosis. A figure shows the Bristol stool form scale. Tables list IBS subtypes, components of digital rectal examination, differential diagnoses for IBS and IBS-C, alarm features, and the American College of Gastroenterology Recommendations.
