Colitis

Ulcerative colitis is a long-term (chronic) condition affecting the colon. Symptoms of ulcerative colitis include bloody diarrhoea, abdominal pain a frequent need to go to the toilet and weight loss. The colon, also known as the large intestine, absorbs nutrients from undigested food and passes out waste products through the rectum and anus in stools (faeces). Ulcerative colitis causes the colon to become inflamed (swollen) and in severe cases, ulcers (painful sores) may form on the lining of the colon. These ulcers can bleed and produce mucus and pus.

Symptoms of ulcerative colitis can range from mild to severe, with the condition being very unpredictable. Symptoms can flare up and then disappear (go into remission) for months or even years.
