The exact cause of irritable bowel syndrome (IBS) is not known. Multiple factors, like genetic, gut motility, visceral hypersensitivity, psychosocial factors and immune-mediated factors, are thought to contribute to the symptom complex of IBS. Till date an 'IBS gene' has not been defined, and there is a need for further studies. The concept that IBS as a diagnosis of exclusion is not acceptable any more. The treatment of IBS is targeted at the management of constipation, diarrhoea and abdominal pain and includes pharmacotherapy with tegaserod, alosetron and lubiprostone. Cognitive behavioral therapy is very beneficial.
