title: The neurologic complications of bariatric surgery.
abstract: Bariatric surgery has been increasingly employed to manage morbid obesity. Approximately 150000 bariatric procedures are performed in the US annually. Neurologic complications arise in as many as 5% of individuals having this surgery. Although the etiology of some of these complications remains obscure, the majority are the consequence of vitamin (most commonly thiamine and vitamin B12) or mineral (most commonly copper) deficiency and familiarity with these disorders is essential. Their rapid diagnosis and appropriate treatment is essential to avoid long-term, irreversible consequences including, in some instances, death.
