Beer potomania: a case report


A syndrome of hyponatraemia associated with excessive beer drinking was first recognised in 1971. This syndrome has been referred to as beer potomania. Dilutional hyponatraemia occurs due to excessive consumption of an exclusive beer diet which is poor in salt and protein. We report a case of beer potomania who improved dramatically with introduction of solute load, with no subsequent neurological sequelae.
