Why is Crohn's disease more likely to cause intestinal obstruction than ulcerative colitis?
Crohn's disease causes granulomas to form in the submucosal layer.
Crohn's disease is located in the small intestine.
Crohn's disease causes abdominal pain and watery diarrhea.
Crohn's disease is exacerbated by certain foods, such as spicy foods.
The Correct Answer is A
A. Crohn's disease can cause granulomatous inflammation that leads to strictures in the bowel, increasing the risk of obstruction.
B. While Crohn's disease often affects the small intestine, ulcerative colitis typically affects the colon, and both can lead to obstructions, but the nature of Crohn's lesions contributes more to this risk.
C. Abdominal pain and diarrhea are symptoms but do not specifically explain obstruction risk.
D. Dietary triggers may exacerbate symptoms but are not a primary reason for increased obstruction risk in Crohn's.
