The superior mesenteric artery syndrome (SMA) is a result of compression of the third part of the duodenum between the aorta and the vertebral column behind and the nerves and vessels of the superior mesenteric bundle in front.

This is thought to occur when the cushion of fat protecting the bundle is lost. The superior mesenteric artery and the duodenum are always side by side.

Why does the SMA syndrome occur in anorexia nervosa? There is a fatty tissue (adipose tissue) that provides padding to many of the organs in the abdomen, including the space between the SMA and the duodenum.

With the serve malnutrition, all the fat on the body decreases as it is used for energy. SMA syndrome may induce remarkable weight loss secondary to recurrent vomiting. The patients assume a typical position when eating: they bend forward.

Symptoms may go undiagnosed for years until they escalate but may also develop acutely or sub acutely, particularly after rapid weight loss.
