What causes ischemic colitis and how do u treat it?

Rx the cause: Marathon runners may develop ischemic colitis with bloody diarrhea simply from the blood supply being diverted during exercise. This self-heals. More often, vascular disease of the superior and inferior mesenteric arterial system, such as atherosclerosis, underlies this problem. Your physician can tell you the likely cause, which perhaps is treatable. Good luck.

Low flow: This can result when the flow of blood and nutrients to the intestines is less than what is needed. This can occur when the intestines have higher than usual needs as with infections often associated with diarhea. This can also occur when the flow is low from an arterial blockage or from dehydration or low blood pressure. Initial treatment is bowel rest, if severe surgery may be needed.
