The physical and psychological burden of these chronic relapsing diseases and their devastating effects imposed on affected children and teenagers may be considerable. Crohn disease and ulcerative colitis are grouped together in view of many similarities in their epidemiologic, genetic, immunologic, and clinical features. Diagnostic approaches are similar, but treatment approaches and prognosis differ.
