title: Hyperinsulinemic hypoglycemia precipitated by weight loss.
abstract: OBJECTIVE
  To describe a case of hyperinsulinemic hypoglycemia precipitated by weight loss.
  
  
  METHODS
  We present a detailed case report and results of a related literature search on hyperinsulinemic hypoglycemia precipitated by weight loss.
  
  
  RESULTS
  The presence of an insulinoma was unveiled by voluntary weight loss and reduction of insulin resistance. Hypoglycemia occurred during the postprandial period and not at night. The diagnostic workup was accomplished without hospital admission.
  
  
  CONCLUSIONS
  Classically, insulinomas present with weight gain and fasting hypoglycemia but may present with postprandial hypoglycemia and weight loss. Voluntary weight loss, by lowering insulin resistance, accelerates the time to clinical presentation of an asymptomatic insulinoma.
