Solitary rectal ulcer syndrome is a condition in which one or more open sores, called ulcers, form in the rectum. The rectum is a muscular tube connected to the end of the colon. Stool passes through the rectum on its way out of the body.
Solitary rectal ulcer syndrome is a rare and poorly understood disorder that can happen in people with long-lasting constipation. It can cause rectal bleeding, pain and straining when passing stool. Despite the name, sometimes more than one rectal ulcer develops in solitary rectal ulcer syndrome.
Solitary rectal ulcer syndrome may improve with simple lifestyle strategies, such as changing your diet and drinking more fluids. In severe cases, however, surgery may be needed.
