This article concerns ischemia of the large bowel. See
mesenteric ischemia for ischemia of small bowel Ischemic colitis (Ischaemic Colitis - British English) is a medical condition in which inflammation and injury of the large intestine result from inadequate blood supply. Although uncommon in the general population, ischemic colitis occurs with greater frequency in the elderly, and is the most common form of bowel
ischemia. Causes of the reduced blood flow can include changes in the systemic circulation (e.g.
low blood pressure) or local factors such as
constriction of blood vessels or a
blood clot. In most cases, no specific cause can be identified.
