General Principles

Heat exhaustion often results from a combination of water and sodium depletion. Water depletion is the result of either overwhelming losses, such as profuse sweating or vomiting, or inadequate replacement. Persons at risk include the elderly, patients taking diuretics, and those working in hot environments with limited water replacement. Salt depletion occurs in unacclimatized individuals who replace fluid losses with large amounts of hypotonic solution.
