smoking in UC

 Q: 37 years old male is admitted to ICU with lower gastrointestinal (GI) bleed. Workup led to diagnosis of ulcerative colitis (UC). Patient recently quit his smoking habit. UC is relatively hard to treat in this patient.

A) True

B) False


Answer: A

Cigarette smoking has a protective tendency in UC. Interestingly, patients who develop UC after quitting tobacco are relatively hard to treat. On the same token, disease severity may improve at the resumption of cigarette smoking. 

In contrast, smoking increases the risk of Crohn's disease (CD) and may make CD symptoms worse.
