Symptoms and UC vs. Crohn's
Hallmarks are bloody diarrhea, mucus in stool, urgency, and a feeling you haven't fully emptied. Inflammation starts in the rectum and extends upward without gaps, staying in the inner lining; Crohn's is patchy and full-thickness. Rectal bleeding is easy to blame on hemorrhoids, so weeks of bloody diarrhea deserve a workup.
Treatment and long-term care
Mild to moderate UC is treated with mesalamine by mouth or as suppositories or enemas. Flares may need steroids, and harder cases use immunomodulators, biologics, or JAK inhibitors. Long-standing colitis raises colon cancer risk, so surveillance colonoscopy usually starts about 8 years after diagnosis (see colon polyps). Stopping meds on your own often triggers relapse.
