Acute mental status changes following an ultramarathon
from British Paramedic Journal
Exercise-associated hyponatremia is an abnormally low blood sodium concentration occurring during or up to 24 hours after physical activity. It is relatively common in some activities, and has been the cause of death across a wide array of activities. Exercise-associated hyponatremia is recognisable through patient presentation and a history consistent with excessive fluid intake, and may even occur with considerable sodium intake during the exercise or sporting event.
