Knowing what patients with irritable bowel syndrome (IBS) want or expect from their medical care is critical in helping them manage the symptoms of this common, chronic gastrointestinal condition. Failure to identify patient expectations can lead to patient dissatisfaction with care, lack of compliance with prescribed treatments, and the inappropriate use of medical resources.

Several studies suggest that IBS patients value the relational aspects of medical care as highly as technical skills and knowledge. There seems to be a significant communication gap between health care providers and patients regarding IBS care. This article reviews what is known about IBS patients' expectations and needs.
