Since 1835, St Mark’s Hospital has improved the survival and health-related quality of life of people with complex and rare bowel diseases. Over 50,000 patients are cared for at St Mark’s and, as a tertiary referral centre, 60% of our patients are referred from other UK hospitals to receive specialist care. Our clinical teams are experts when it comes to anything related to gastrointestinal diseases; in 2022, St Mark’s was recognised by Newsweek Magazine as one of the world’s leading specialist hospitals for gastroenterology.
