Dilutional hyponatremia in preeclampsia with and without nephrotic syndrome

This report includes cases of hyponatremia in preeclampsia. Two patients were identified with preeclampsia complicated by hyponatremia, one with and the other without nephrotic syndrome. Together with 3 cases of hyponatremia recently reported, these additional cases from the same geographic area suggest that hyponatremia is not a rare complication of preeclampsia.
