Superior Mesenteric Artery Syndrome (SMAS) is a rare condition that occurs when the superior mesenteric artery (SMA) compresses the third part of the duodenum, the small intestine's first section. This compression can cause severe abdominal pain, nausea, vomiting, and difficulty eating. It is most commonly seen in people who have lost a significant amount of weight, such as those with anorexia nervosa. Treatment typically involves dietary changes and medications to reduce the pressure on the duodenum. In some cases, surgery may be necessary to relieve the compression.
