About a year ago, after a year of chronic diarrhea, I had my first colonoscopy. The diagnosis was lymphocytic colitis. I've been on uceris for about a year. It works well, but, I'd like to learn more about LC. So far I've researched that it APPEARS to be an autoimmune disease. Steriods daily keep the diarrhea at bay. There appears to be a link to sulfa drugs, but nobody really knows. I had been taking celebrex, and on agreement with my Primary Care Doc, stopped taking it. I'm going to be going to an allergist soon. To see if I can find out if I'm allergic to sulfa type drugs. Sigh. ???
