The initial laboratory test revealed hyponatremia and hypoglycemia (Table 1), and low plasma ACTH and serum cortisol levels at 08:00 AM (ACTH < 1.5 pg/ml, reference range 8.7–61.5 pg/ml; cortisol 1.6 μg/dl, reference range 7.07–19.6 μg/dl at 06:00–10:00 AM), suggesting secondary adrenocortical deficiency. Here, POMC is linked to Hypoglycemia.
