Current approach to hyponatremia

Abstract

Hyponatremia is the most common electrolyte disorder. Hyponatremia may appear with a great variety of clinical findings depending on the underlying cause and way of onset. Thus, management of hyponatremia varies according to each patient. While acute onset hyponatremia requires emergent therapy since it may cause brain edema, chronic hyponatremia may cause a severe neurological condition named osmotic demyelination syndrome if treated aggressively. This review explains the current approach to hyponatremia with case reports.
