Ischemic colitis is a condition that happens when a portion of the large intestine loses, or has restricted blood flow. This condition is usually caused by blood vessels that have narrowed or become blocked. The reduced blood flow does not allow enough oxygen into the intestines to keep the tissue of the digestive system alive.
Ischemic colitis can affect any part of the colon. However, it is most commonly found in the large intestine. The condition is easy to misdiagnose because it mimics many other digestive issues. The condition has been known to heal on its own in the majority of cases. However, some people need medication in order to treat the disorder and prevent infection from the reduced blood flow to tissues. If the colon has been damaged, it is possible that surgery may be required.
The symptoms of ischemic colitis can be easy to overlook or dismiss as a digestive upset or other condition of the digestive system.
There are risks of complications developing due to lack of blood flow. However, people who suffer from symptoms on the right side of the stomach have more of a risk of developing complications. This is because the arteries that are on the right side of the belly supply oxygen to the small intestine, and these arteries can become blocked too. The pain is also known to be worse if the small intestine suffers from reduced blood flow.
When the small intestine is involved, the blockage is more capable of causing tissue death. Tissue death in the small intestines can lead to a condition known as sepsis, or a full body infection. This quickly becomes a life threatening situation and surgery is needed to remove the damaged part of the intestine, as well as restore blood flow to the remaining portion.
The treatment for ischemic colitis will depend on how severe you condition is, and the portion of the intestine that is suffering from reduced blood flow, or total loss of blood flow. The symptoms of a mild case of ischemic colitis diminish after a few days.
Even though most cases of ischemic colitis resolve on their own, cases where severe symptoms are present may not. If your doctor has determined that there is damaged tissue, you may need to have surgery.
If you have an underlying heart condition, or low blood pressure, you are more likely to require surgery to repair a damaged portion of your colon, or restore blood flow to the affected area.
