Angiodysplasia of the colon occurs when enlarged and fragile blood vessels in the colon result in occasional bleeding in the gastrointestinal (GI) tract. If you think you may have this condition, contact your doctor immediately.
Angiodysplasia of the colon can be caused by:
- Injury to the GI tract
- Heart problems
- Kidney problems
- Lung problems
- von Willebrand's disease (a disorder of the blood)
- Blood vessel problems
- Normal contractions of the colon
A risk factor is something that increases your chance of getting a disease or condition. If you are over 60 years old, you are at increased risk of having angiodysplasia of the colon.
