Hyperinsulinism-Hypoglycemia in the Postgastrectomy Patient

Abstract

Patients who had undergone gastric resection were studied with blood glucose and serum insulin levels during oral glucose tolerance testing. The symptoms which appear two to three hours after a glucose load follow a marked rise in serum insulin and are accompanied by hypoglycemia. By appropriate elevation of the blood glucose, high seruminsulin levels and a similar secondary hypoglycemic syndrome can be produced in normal individuals.
