Ischemic colitis is a sudden swelling (inflammation) of part of the large intestine (colon) that occurs when there is a temporary loss of, or reduction in, blood flow to the colon.
Causes, incidence, and risk factors
Ischemic colitis mainly affects people over 50. Many of them have a history of peripheral vascular disease.
Other risk factors include:
Signs and tests
Treatment for mild ischemic colitis often involves:
- Liquid diet at first
- Fluids through a vein (by IV)
- Pain medications
Severe ischemic colitis that leads to gangrene is treated with:
- Replacement of blood volume
- Surgery to remove the affected bowel area
Most cases of ischemic colitis are mild and will improve on their own. They do not need surgical treatment.
The death rate is high when gangrene occurs because there is not enough blood supply.
- Gangrene of the bowel
- Hole in the intestine (perforation)
- Inflammation of the lining of the abdomen (peritonitis)
Calling your health care provider
Call your health care provider if you develop symptoms of ischemic colitis.
Being aware of your risk may allow early diagnosis and treatment. Absolute prevention may not be possible.
