Which condition is a chronic inflammatory disease of the intestines, potentially affecting from mouth to rectum?

• A. Gastritis
• B. Crohn's Disease
• C. Diverticulitis
• D. Tuberculosis

Answer: (B)

Crohn's disease is a chronic inflammatory bowel disease that can involve any part of the gastrointestinal tract, from the mouth to the rectum. The inflammation is often transmural, affecting the full thickness of the bowel wall, which can lead to complications like fistulas and strictures and cause persistent abdominal pain with diarrhea. This description fits a disease that can span the entire GI tract, unlike gastritis (inflammation of the stomach lining), diverticulitis (inflammation of colon diverticula, usually localized to the colon), or intestinal tuberculosis (infection rather than a chronic inflammatory bowel disease that naturally involves the entire tract).
