Ulcerative colitis & smoking
Ulcerative colitis is one of the few diseases for which smoking has some benefits.
Smoking reduces the risk of getting ulcerative colitis.
In addition, when people with ulcerative colitis quit smoking, the disease can flare up.
Experts thought that nicotine might explain the effects of smoking on ulcerative colitis. Now they aren’t sure. When nicotine chewing gum and transdermal patches have been tested in clinical trials, they haven’t produce much benefit.
