Intestinal ischemia occurs when blood flow to the intestines is reduced, leading to a lack of oxygen and nutrients. This condition can result from various factors, including blood clots, narrowed blood vessels, or low blood pressure. Symptoms may include abdominal pain, nausea, and changes in bowel habits. If left untreated, intestinal ischemia can cause serious complications, such as tissue death or perforation of the intestines. Diagnosis typically involves imaging tests like CT scans or ultrasound, and treatment may include medications, surgery, or procedures to restore blood flow. Early intervention is crucial for better outcomes.
