Ulcerative colitis is an inflammatory bowel disease that affects the colon and rectum, causing the lining to become inflamed and develop ulcers. People with this condition experience symptoms like bloody diarrhea, abdominal pain, and urgency to use the bathroom—sometimes dozens of times daily. The disease typically develops in adulthood, though it can occur at any age, and symptoms may come and go over time, with periods of flare-ups and remission.
These articles explain what happens in the body during ulcerative colitis, how doctors diagnose it, and what treatment options exist—from medications that reduce inflammation to surgical approaches when needed. You'll find information about managing symptoms day-to-day, understanding how diet and stress may affect flare-ups, and what the long-term outlook looks like for people living with this condition.
