OBJECTIVE: The pathophysiology and symptomatology of the superior mesenteric artery syndrome (SMA syndrome) is discussed. METHOD: A review of much of the available literature concerning the SMA syndrome and the associated condition acute gastric dilatation is offered. RESULTS: Two new cases of acute gastric dilatation in patients with eating disorders, one of whom was diagnosed with SMA syndrome, are presented, along with a discussion of these conditions in reference to the eating disorders. CONCLUSION: The SMA syndrome and gastric dilatation are rare but potentially a very serious complication of eating disorders, and clinicians who work with these patients should be aware of such problems.
