persistent infant hyperinsulinemic hypoglycemia

Abbreviation: PHHI
The most common cause of recurring low blood glucose levels in newborns. PHHI is typically caused either by diffuse overgrowth of insulin-secreting cells (beta cells) throughout the pancreas or by a single beta cell adenoma. It is characterized by the abnormal secretion of insulin despite low blood glucose levels. Neonates affected by PHHI may suffer brain injury caused by low blood glucose levels.
Synonym: congenital hyperinsulinism
