Question

Quizplus · Accepted Answer

Ulcerative colitis specifically affects the large bowel (colon) and rectum, which makes it more likely to result in secondary acquired lactose intolerance due to diffuse intestinal damage. Celiac disease and Crohn's disease can affect any part of the digestive tract, including the small intestine, but are not specifically associated with large bowel involvement. Peptic ulcer disease is not an IBD and does not involve the large bowel.
