How might superior mesenteric artery syndrome be treated? 

Treatment for superior mesenteric artery syndrome typically focuses on addressing the underlying cause of the condition.[1] For example, symptoms often improve after lost weight is restored or a body cast is removed.[2] Nasogastric decompression (a tube passed through the nose into the stomach) and proper positioning after eating (such as lying prone and knee-to-chest position) may be recommended to alleviate symptoms.[1]

In severe cases, intravenous (IV) nutritional support and/or a feeding tube may be needed to provide enough calories. Affected people can usually then be started on oral liquids, followed by slow and gradual introduction of small and frequent soft meals as tolerated. Then, regular solid foods may be introduced. Metoclopramide treatment may be beneficial for some people.[1]

Surgery may be needed if other treatment strategies do not work. However, other treatment options should usually be tried for at least 4-6 weeks before considering surgery.[1]
