What is ulcerative colitis?
Ulcerative colitis is a superficial inflammation of the large intestine, not caused by bacteria, which results in ulceration and bleeding.
The patient typically experiences alternating periods with no or few symptoms, and periods with frequent stomach pains and diarrhoea that is mixed with pus, blood, and mucus.
It’s rare in the UK, with one new case per 10,000 people per year. Currently, there are approximately 146,000 patients with ulcerative colitis and usually they are diagnosed between the ages of 15 and 25-years-old, with a smaller peak between 55 and 65 years old.
People of Asian origin are less likely to be affected, and men and women are equally affected.
