I have Crohn's disease and I heard that smoking was bad for a Crohn's patient, however, for a patient with colitis ulcer, "nicotine" could have a positive effect on the colitis ulcer. Can you confirm this, and explain this please? Thank you for your answer. I like the MedicineNet a lot and have been using it to learn more about my own disease. We do not have anything like this here in Denmark.
It has been reported in many studies that cigarette smoking causes Crohn's disease to become worse yet causes ulcerative colitis to become better. The reason for this is unknown. One must also keep in mind that although smoking may be slightly beneficial for ulcerative colitis, it increases the risk of lung and cardio-vascular disease for both the individuals who smoke and others around him or her.
