Apparent hypocortisolism in an infant with prolonged hyperinsulinism.

ABSTRACT

We report a case of transient hyperinsulinism with hypocortisolemia in a preterm small for date neonate with recurrent hypoglycemia and perinatal stress. Investigation revealed increased Insulin level with subnormal cortisol level even during hypoglycemia. Hypoglycemia resolved by its own by 22nd day of life with normal insulin and cortisol level thereafter.
