It tough for me to answer because I have gone through different stages with having this disease over the last 20 years. I will try however.
I used to be flaring all the time although I didn't know it. This was before I was officially diagnosed with UC. I had gone to the doctors and tried to explain my symptoms but they didn't put it together until I was just gushing blood and mucus. Then for years I was taking Asacol with on and off again prednisone but I was still flaring 5-6 times a year.
The duration of each flare lasted about a few weeks to a few months with very little time for remission making it feel like one long flare. This went on for about 10 years.
I would have to say I tried to stay on the ASA meds but my colits got worse over the years and eventually I had to switch to Imuran which put an end to my ulcerative colitis. So my colitis got worse but I feel it got worse because I wasn't taking the right medication for it. Once I got on the Imuran my UC has basically dissapeared. I only go for a BM once a day, almost same time every day, no urgency, no blood or mucus, just normal. My last colonscopy was basically completely normal. So for now at least I got a grip on it. Again, things may change in the future but it sure is nice to live a normal life never thinking about a toilet.
