Abstract
This article presents the case of a 52-year-old woman who developed exercise-associated hyponatremia (EAH) complicated by non-cardiogenic pulmonary edema after a marathon run. The condition of EAH is a potentially life-threatening complication of endurance exercise. The main cause seems to be inadequate intake of free water during or following exercise with enduring antidiuresis due to nonosmotic stimulation of ADH secretion. Known risk factors are female gender, slow running pace and lack of weight loss. Emergency therapy is fluid restriction and bolus infusion of 3% NaCl solution to rapidly reduce brain edema.
