Mesenteric ischemia is a condition that occurs when blood flow to the intestines is reduced, leading to insufficient oxygen and nutrients for the intestinal tissues. This can happen due to blockages in the blood vessels, often caused by atherosclerosis, blood clots, or other vascular issues. Symptoms may include abdominal pain, nausea, and changes in bowel habits. If left untreated, mesenteric ischemia can result in serious complications, such as intestinal tissue death or peritonitis. Diagnosis typically involves imaging tests like CT scans or ultrasound, and treatment may include medications, surgery, or procedures to restore blood flow.
