A Rare Etiology of Hyponatremia: Beer Potomania

Electrolyte abnormalities can be observed in chronic alcoholic patients. Hyponatremia is one of them. Beer potomania is an unusual cause of hyponatremia and was first described by Gwinup et all. in 1972. Patients usually have a history of binge beer drinking and poor solute intake. We present here a 48-year-old male patient who had hyponatremia secondary to binge beer drinking.
