Ian,
I can only speak from my own experience here. I was diagnosed with UC in 1998. Had to be hospitalized at that time for eight days. Suffered with the flare about two months and then enjoyed two years of remission. Unfortunately, since I was feeling so well and NOT much of a pill consumer, I took myself off the Asacol. Well, back in a flare in 2000, back on the prednisone and Asacol. Stayed with the Asacol but in 2002, another flare. This time the doctor switched me from Asacol to Colazal because my UC is in the rectum. Flare lasted two months again. In fall of 2003, another flare, this one lasted five months. Then the doctor put me on the 6MP, which I was very hesitant to start, but hey, if it would help. Remission lasted about a year and a half. Sorry to say the 6MP has not kept me in remission and now, more or less, I have become prednisone dependant. I suffer a flare every year and this last one landed me in the hospital in May for ten days. The two times since May I was weened off the pred, boom, more D, blood and urgency. Now back on the pred, 40 mgm to jump start again and then slow ween.
about the surgery. I saw a colorectal surgeon in August. He is supposed to be one of the top ten colorectal surgeons in the country. He said I am NOT a candidate for surgery...yet. He thought my condition mild to moderate. Severe seems to be going in upwards of 20 times a day, with bleeding, anemia and loss of considerable amount of weight. So there you have it. I do bleed but do not have anemia, loss 19 lbs...do NOT want to lose anymore. I am also 62 yrs old, so quite old considering most of you in this forum. Hope this helps.
