Recently, I have to urinate much more frequently. At night, I used to have to get up only once, but, in the last few months, I have to get up 2-3 times. During the day, I used to have to pee only once, but, again, lately, it's 2-3 times a day, and sometimes 4. I do not see any blood in the bowl. I have had diagnosed ulcerative colitis since 1976 and have been on sulfasalizine ever since. I have colonoscopies at least every five years and had the last one last spring. The issue is not with #2 but rather #1. I belong to Kaiser and will see my GI doc this Friday, and I'm curious as to what might be going on. Gall bladder?
