title: Metformin-induced lactic acidosis with emphasis on the anion gap.
abstract: The presence of an anion gap in a diabetic patient, especially if associated with evidence of compromised renal function, should prompt clinicians to consider metformin as a contributing factor. This consideration is especially important in patients with severe anion gaps associated with lactic acidosis out of proportion to the patient's clinical presentation.
