Risk factors for ischemic colitis include:

  • Age. The condition occurs mostly frequently in adults older than age 60. Ischemic colitis that occurs in a young adult may be a sign of a blood-clotting abnormality or inflammation of the blood vessels (vasculitis).
  • Clotting abnormalities. Conditions that affect the way the blood clots, such as Factor V Leiden, may increase the risk of ischemic colitis.
  • High cholesterol, which can lead to atherosclerosis.
  • Reduced blood flow, due to heart failure, low blood pressure and shock.
  • Previous abdominal surgery. Scar tissue that forms after surgery may cause reduced blood flow.
  • Heavy exercise, such as marathon running, which can lead to reduced blood flow to the colon.
  • Surgery involving the large artery (aorta) that pumps blood from your heart to the rest of your body.
