[Hyponatremia due to prolonged excessive ingestion of water].
We report a 1.5-year-old boy admitted for restlessness and constipation. He was found to have hyponatremia caused by voluntary drinking of excessive amounts of water. Although unusual in children, intoxication by oral water is a recognized clinical syndrome in infants, 3-6 months old, fed with dilute formula. Water intoxication in older children is rare. The diagnosis was established by the water deprivation test.
