description: "Diazoxide-resistant focal hyperinsulism (DRFH) is a form of diazoxide-resistant hyperinsulinism characterized by recurrent episodes of profound hypoglycemia caused by an excessive/ uncontrolled insulin secretion (inappropriate for the level of glycemia) due to a focal adenomatous hyperplasia of pancreas, that is unresponsive to medical treatment with diazoxide, necessitating complete excision of the focal lesion."
