Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) that affects the inner lining of the large intestine (colon) and rectum. Unlike Crohn’s disease, which can affect any part of the gastrointestinal tract and penetrate deeper tissue layers, ulcerative colitis typically only affects the colon and rectum, and inflammation is usually limited to the innermost mucosal layer. The condition often begins gradually and can worsen over time, leading to symptoms that may interfere with daily life.
Ulcerative colitis is considered an autoimmune condition, where the immune system mistakenly attacks the cells lining the colon, leading to persistent inflammation and the formation of ulcers. The exact cause is unknown, but it’s believed to involve a combination of genetic, environmental, and immune-related factors. The disease often follows a pattern of flare-ups and remission, which can make it unpredictable and emotionally challenging for those living with it.
Ulcerative colitis can cause long-term inflammation and ulcers in the colon. When not managed properly, it can lead to complications such as severe bleeding, perforated colon, and an increased risk of colon cancer. Early diagnosis and proper management can significantly reduce complications and improve quality of life.
