Core tip: Irritable bowel syndrome (IBS) remains a clinical challenge in the 21st century. Various mechanisms and theories have been proposed about its etiology, but the biopsychosocial model is the most currently accepted. Today the Rome Criteria are the current gold-standard for the diagnoses of IBS. Traditional management of IBS has been symptom based and several drugs have been used. However, the cornerstone of its therapy is a solid patient physician relationship. This review will provide a summary of pathophysiology, diagnostic criteria and current and emerging therapies for IBS.
