Having spent the past 4 weeks in hospital, I regularly went outside for a cig. On one of the occasions, my GI Doc walked passed and came over to talk to me, I threw the cig away. That was in the first week.
On the night before I was discharged, he was in one of the wards talking to a patient that my wife and I had got friendly with (Bowel Cancer). He then started a nice, friendly conversation with us.
Just before he left, he said to my wife, "get him off the cigarettes, they are very bad for his Crohn's". He has never said anything to me in the last 10 years, but he didn't target me, only my wife... Cleaver man. I've been nagged since I came home constantly.
To be honest, I have been planning to quit after Christmas for some time now, but this little episode has spurned me on.
I've always known about the link between nicotine and Cohn's, and also the link between Nicotine and Collitis (It's known to help!!!).
My advise (from a current smoker) is quit. Maybe we can help each other?
