Case in brief

A 7-day-old girl was hospitalized for excessive weight loss. Initial testing showed hyponatremia and hyperkalemia, prompting evaluation for endocrine, renal, and metabolic causes. Supportive interventions were provided, and her weight and electrolyte abnormalities gradually improved during hospitalization. Imaging and genetic testing were also undertaken to clarify the underlying cause; the abstract does not specify the final diagnosis or test results.

Diagnostic / clinical pearl

In a neonate with excessive weight loss and hyponatremia with hyperkalemia, assess endocrine, renal, and metabolic causes while providing supportive care; imaging and genetic testing may contribute to clarifying the etiology.
