Which two diseases are classified as inflammatory bowel disease?

• A. Ulcerative colitis and Crohn's disease
• B. Irritable bowel syndrome and celiac disease
• C. Gastritis and GERD
• D. Diverticulitis and appendicitis

Answer: (A)

Inflammatory bowel disease refers to chronic inflammatory conditions of the gastrointestinal tract. The two diseases classically grouped as IBD are ulcerative colitis and Crohn's disease. Ulcerative colitis involves continuous inflammation limited to the colon and rectum, primarily affecting the mucosal lining. Crohn's disease can affect anywhere along the GI tract from mouth to anus and often features full-thickness (transmural) inflammation with skip areas where normal tissue lies between inflamed segments. Both share an autoimmune/inflammatory process and similar clinical features such as abdominal pain and diarrhea, and they may require medical therapy and, in severe cases, surgical options like ostomies to manage the disease or its complications. Other options don’t fit IBD because irritable bowel syndrome is a functional disorder without the inflammatory component; celiac disease is an autoimmune reaction to gluten affecting the small intestine but is not classified as IBD; gastritis and GERD involve inflammation of the stomach or esophagus rather than the intestinal tract; diverticulitis and appendicitis are acute inflammations of specific GI regions rather than chronic inflammatory bowel disease.
