Current evidence strongly indicates that EAH is a dilutional hyponatremia, caused by an increase in total body water relative to the amount of total body exchangeable Na+ (1,4,21-23,26-30,33,35,36,39,46,48,53,55).
Excessive Na+ loss has not been demonstrated to be a primary causative factor in the pathogenesis of EAH.
There is no currently available evidence to support the suggestion that Na+ supplementation prevents the development of EAH (66,76) nor is there any evidence that consumption of electrolyte-containing hypotonic fluids (ie, sports drinks) can prevent the development of EAH in athletes who drink to excess (20,67).
