What causes superior mesenteric artery syndrome?

A variety of factors can contribute to the development of superior mesenteric artery syndrome (SMAS), including:[1]
  • prolonged bed rest
  • rapid, severe weight loss
  • rapid growth
  • previous abdominal surgery
  • lordosis
  • use of body casts
  • loss of tone in abdominal muscles

SMAS has also been reported to occur in some people with pancreatitis, peptic ulcers, and other inflammatory conditions of the abdomen.[1] Rarely, the condition may be caused by an abnormality in the structure of the body (such as unusual position or location of the artery). Familial SMAS, recurrent SMAS, and idiopathic neonatal SMAS have also been reported.[2]
