(Ischemic Colitis)

Definition

Ischemic bowel disease results from inadequate flow of oxygenated blood to the intestines. The extent of ischemic bowel disease can range from mild to severe based on the amount of damage from lack of oxygenated blood. This is a potentially serious condition and immediate medical care.
