The credibility of the authors is impeccable. Dr. Drossman’s entire career, often mediated via his efforts through the Rome Foundation, has been devoted to providing the research and conceptual basis for a remarkable evolution in U.S. medicine: DGBI are the most completely described biopsychosocial disorders. This not only helps patients and practitioners but also guides the remainder of medicine in this new direction. Just as compelling is Ms. Ruddy’s personal story as a patient with IBS and how she suffered profoundly until treated by someone who understood the biopsychosocial model.
