Ischemic colitis

Ischemic colitis 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. Causes of the reduced blood flow can include changes in the systemic circulation, such as 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.
