I was in a situation like that... a flare that just didn't want to end. Landed me in the ER, from there to the hospital (again). To make matters worse, at the time the docs couldn't decide if I had UC, CC or CD (or a rare combo of them all). I eventually wound up in a ward with other patients who were long timers when it came to IBD (one fellow was there for his 2nd or 3rd resection). Anyway, nothing was working to stop the flaring/bleeding, and I was getting ... well, scared for one... pissed off because the "EXPERTS" didn't seem able to do anything, when a couple of the veterans told me that if I started smoking, it would stop. I didn't believe them at first. They said to ask the next doctor I saw. I did. He said no, but something about the way he said it made me .. I dunno.. suspicious. So, I kept asking every doc, intern, out-turn, resident, GI, GP or other doctor I ran into the same question. One doctor reluctantly admitted that smoking was the 'old' cure for UC. Then a 2nd, equally reluctantly, confirmed that. It is not something doctors will admit, talk about, discuss, etc., unless they're pressured. So, to make a long story short, I got my hands on some cigarettes, and within 24 hours my uncontrolled bleeding slowed to a trickle, and stopped altogether within 48 hours. No bull. Now, heres the catch. If your UC should turn out to be CC or CD, then smoking CAN affect whether your meds will work. Smoking can actually make those forms of IBD a lot worse. Go figure. Anyway, fast forward... I go on LDN, my Crohns comes under control, stays that way for a year, and I figure... OK, this would be a great time to quit smoking. My GI thought it was worth a try, and the plan involved nicotine replacement therapy, (which is what the docs thought was the part of smoking that kept UC bleeds under control).. I went to see specialists at Smoking Cessation clinics, and they were very guarded about the outcome of this little experiment. Within 6 weeks of quitting, the bleeding started again. I became enemic, and that took nearly a year to set right. Again, within 24 hours of resuming smoking, the bleeding abruptly stopped. End of story.
Tobacco is poison. It will kill. But, in the overall scheme of things, many IBD meds may do the very same. My take on fighting whichever form of IBD a person has remains the same... you find something that works, stick with it, worry about the consequences IF or WHEN they arise. As 'patients' (I don't like to think of myself or anyone else with this illness a 'victim') I don't think ANYONE should expect us to 'cure ourselves' or defend the choices that we make (many of which are forced upon us) until that glorious day when the "EXPERTS" find a cure.
