🔍 What causes it
Autoimmune inflammation of the large intestine's inner lining (colon). Genetics + immune response to gut bacteria. A form of inflammatory bowel disease (IBD) — related to but different from Crohn's.
⚠️ Key symptoms
- Frequent, urgent diarrhea with blood/mucus
- Abdominal cramps
- Weight loss and fatigue
- Flare-ups and remissions
💊 Treatment
Anti-inflammatory medicines (5-ASAs), steroids for flares, immunosuppressants/biologics for moderate-severe. Diet and stress management help. Some need surgery (colectomy) if medicine fails. See a gastroenterologist.
🛡️ Prevention
Not preventable, but staying on maintenance treatment prevents flares; avoid NSAIDs which can worsen it.
🚨 See a doctor / red flags: See a doctor promptly if symptoms are severe, do not improve, or get worse — especially for children, older adults, pregnant women, or anyone with a chronic condition.
