Management of irritable bowel syndrome (IBS) in adults: conventional and complementary/alternative approaches.

Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder with a range of symptoms that significantly affect quality of life for patients. The difficulty of differential diagnosis and its treatment may significantly delay initiation of optimal therapy. Hence, persons with IBS often self-treat symptoms with non-prescribed pharmacological regimens and/or complementary and alternative medicines (CAM) and by modifying diet and daily activities.
