Superior Mesenteric Artery Syndrome (SMAS)

Superior Mesenteric Artery Syndrome is a rare medical condition that occurs when the first part of your small intestine is compressed between the aorta and the superior mesenteric artery. This blockage causes issues when it comes to food trying to travel through the duodenum and leads to bowel obstruction within the small intestine.

The symptoms of SMAS vary, but they may include:

  • Feeling full quickly when eating
  • Bloating after meals
  • Belching
  • Nausea and vomiting of partially digested food or bile-like liquid
  • Small bowel obstruction
  • Weight loss
  • Mid-abdominal “crampy” pain that may be relieved by the prone or knee-chest position or by lying on the left side
