Hypernatremic dehydration in breast-fed infants

Wis Med J. 1995;94(3):143-5.


Three cases highlight the association between elevated breast milk sodium and hypernatremic dehydration in the infant. All three mothers, breast-feeding exclusively, had sodium levels in breast milk elevated significantly above normal. Severe hypernatremic dehydration in otherwise normal infants who are exclusively breast fed can be due to elevated sodium levels in breast milk.
