Is Superior Mesenteric Artery Syndrome contagious?

Superior Mesenteric Artery Syndrome is not a contagious disease and cannot be transmitted from person to person through contact, air, or bodily fluids. It is a rare anatomical condition caused by the compression of the duodenum between the aorta and the superior mesenteric artery, meaning there is zero risk to family members or caregivers.

What is the actual cause of Superior Mesenteric Artery Syndrome?

Superior Mesenteric Artery Syndrome is a mechanical, anatomical disorder rather than an infectious or genetic one. It occurs when the pad of fat that normally cushions the duodenum is depleted, causing the mesenteric artery to compress the bowel. This often follows rapid, significant weight loss, prolonged bed rest, or spinal surgery, which can reduce the angle between the aorta and the superior mesenteric artery.

Why is there no risk of contagion?

Because Superior Mesenteric Artery Syndrome is purely physical and anatomical, it lacks any infectious agent such as a virus, bacteria, or fungus. You cannot "catch" Superior Mesenteric Artery Syndrome from someone else. Living with, hugging, or sharing household items with an individual diagnosed with Superior Mesenteric Artery Syndrome poses absolutely no health risk to others.

What are the primary factors contributing to this condition?

While not contagious, the development of Superior Mesenteric Artery Syndrome is often linked to specific medical scenarios that result in the loss of mesenteric fat. Common contributing factors include:

• Rapid, unintentional weight loss due to illness or eating disorders.


• Surgical procedures that affect the alignment of the spine, such as scoliosis correction.


• Conditions that require strict, long-term immobilization or bed rest.


• Anatomical variations present from birth that predispose the vessels to narrow the arterial angle.

Addressing stigma and misconceptions

Patients with Superior Mesenteric Artery Syndrome sometimes face social isolation due to misconceptions regarding their chronic digestive symptoms. It is vital to understand that this condition is a structural mechanical problem. With over 380 members in our DiseaseMaps.org community, we emphasize that Superior Mesenteric Artery Syndrome is a medical challenge that requires specialized gastroenterological care, not social distancing or quarantine.

Next steps

• Consult a gastroenterologist or vascular surgeon to discuss imaging studies like a CT angiogram.


• Connect with the 380 community members at DiseaseMaps.org for peer support.


• Focus on nutritional management under the guidance of a registered dietitian to restore necessary body fat.
