Diverticular Disease: Severe Bleeding
Severe bleeding (diverticular hemorrhage) is a separate problem from diverticulitis. Severe bleeding occurs in less than 5% of people with bleeding from diverticula in the colon. Bleeding stops on its own in about 75% of cases.1 But sometimes, bleeding may be severe enough that a blood transfusion is needed.
Imaging tests including angiography (also known as arteriography) may be used to find the location of persistent bleeding. Angiography also can be used to deliver medicines to the site to help stop the bleeding. Doctors also may use colonoscopy to apply medicines or instruments to try to stop bleeding.
If these methods do not work, surgery may be necessary to prevent repeated problems with bleeding.
