As these events have become more popular the incidence of serious hyponatremia has increased and associated fatalities have occurred. In most cases exercise-induced hyponatremia is attributable to excess free water intake which fails to replete the some-times massive sodium losses that result from sweatingThe risk of hyponatremia can be lowered by. Exercise-associated hyponatremia EAH is defined by a below-normal serum sodium concentration 135 mmolL during or up to 24 hours after physical activity.

Hyponatremia is due to a combination of excessive water or hypotonic fluid intake as well as high levels of arginine vasopressin. Disorders of serum sodium concentration occur commonly in athletes participating in endurance sports. The pathogenesis of EAH is best described as a spectrum ranging between profound polydipsia to modest sweat sodium losses with hypovolemia and relative dilution.

Exercise-associated hyponatremia EAH is the development of a low serum sodium in association with endurance exercise of any type.

16 EAH is dichotomized into asymptomatic and symptomatic cohorts. The influence of pre-exercise carbohydrate status combined with high volume fluid intake on sodium concentrations and fluid balance. While hypernatremia is the most commonly seen disorder hyponatremia can occur in 2 to 7 of participants.

EAH has been reported in nearly every form of endurance activity and has a common pathogenic feature of excessive water intake which is usually coupled with elevated vasopressin. Exercise-induced hyponatremia is most commonly associated with prolonged exertion during sustained high-intensity endurance activities such as marathons or triathlons.
