Diagnosis and management of irritable bowel syndrome: a guide for the generalist

Abstract

Irritable bowel syndrome (IBS) and other functional gastrointestinal disorders (FGIDs) are so prevalent they cannot reasonably have their diagnoses and management based within specialty care. However, delayed diagnosis, lengthy wait times for specialist review, overinvestigation and lack of clear diagnostic communication are common. The intrusive symptoms of IBS and other FGIDs impair patient functioning and reduce quality of life, and come with significant costs to individual patients and the health care system, which could be reduced with timely diagnosis and effective management. IBS, in particular, is no longer a diagnosis of exclusion, and there are now effective dietary and psychological therapies that may be accessed without specialist referral.The faecal calprotectin test is widely available, yet not on the Medical Benefits Schedule, and a normal test result reliably discriminates between people with IBS and patients who warrant specialist referral.
