The incidence and factors associated with dysnatremia in children with acute gastritis/gastroenteritis.

Dysnatremia was common in children with acute gastritis/gastroenteritis. Moderate to severe dehydration and the presence of vomiting and diarrhea simultanously were significantly associated with dysnatremia at presentation. Furthermore, presenting with vomiting and diarrhea silmutaneously was associated with hyponatremia at presentation. Serum electrolytes should be monitored in patients with those conditions.
