Hi, some heart conditions, like atrial fibrillation can throw out emboli which can get lodged in blood vessels of the colon and cause ischemia. So, it depends on the heart condition. The other common cause are atherosclerosis and it can also occur due to certain medications like chemotherapy. Ischemic colitis may heal on its own and it can recur. But you may need medication to treat or prevent infection, or surgery if your colon has been damaged. Please discuss this with your doctor am sure he will provide further assistance. Regards.
Hi, do you have heart failure now? as this can diminish the blood flow to the colon. Besides this hypovolemia, hypotension and blood clots can aggravate ischemic colitis.

Please discuss this with your doctor am sure he will provide further assistance. Regards.
