Low-solute hyponatremia is a relatively uncommon entity of euvolemic hyponatremia. Classic cases were described in alcoholics as beer potomania, which is characterized by hyponatremia in the setting of low-solute intake due to heavy beer drinking. We report a case of low-solute hyponatremia in a nonalcoholic person who was given a solute load, and, subsequently, had excessive diuresis with the resultant rapid increase in serum sodium concentration.
