Severe Hypernatremic Dehydration in an Exclusively Breastfed Neonate.

Neonatal hypernatremic dehydration is a serious condition associated with inadequate fluid intake, often due to insufficient lactation. In addition to the complications directly related to the condition itself, the re-establishment of plasma tonicity may also lead to serious consequences if done abruptly. Management involves careful fluid restoration and gradual correction of electrolyte imbalance. The increasing incidence of this clinical condition highlights the importance of raising awareness among parents and healthcare professionals for early diagnosis and prevention. We report a case of severe hypernatremic dehydration in a 16-day-old exclusively breastfed newborn, emphasizing its clinical management.
