N2 - A 9-day-old infant girl presented with diarrhea and weight loss of 19% since birth. She was born via spontaneous vaginal delivery at 39 weeks' gestation to a mother positive for group B Streptococcus who received adequate intrapartum prophylaxis. The infant was formula-fed every 2 to 3 hours with no reported issues with feeding or swallowing. The infant had nonmucoid watery stools ∼5 to 15 times per day. Her family history was significant for hypertrophic cardiomyopathy in several of her family members. Her initial vital signs and physical examination were normal. Laboratory data on hospital admission showed a normal complete blood cell count, but her chemistry analysis revealed significant hypernatremia, hyperkalemia, metabolic acidosis, and acute kidney injury. Her hypernatremia was resistant to fluid management. In this article, we discuss the infant's hospital course, our clinical thought process, and how we arrived at our final diagnosis.
