Hyponatremia (Low Sodium) (cont.)
IN THIS ARTICLE
Studies have suggested that long distance runners develop hyponatremia not infrequently after prolonged exercise and should drink adequate amounts of fluid to match their thirst requirements as well as replace sodium along with water during prolonged or extreme exercise. Ideally, a person should not lose more than 2% of their body weight during exercise in order to prevent dehydration and electrolyte abnormalities.
People who exercise and consume too much water, on the other hand, are at risk for water intoxication and low blood sodium levels. One should take care not to not gain weight due to water consumption during exercise.
Infants should not be fed plain water because their kidneys are not able to adequately concentrate urine, therefore leading to hyponatremia and other electrolyte disturbances.
