Hypoinsulinemic Hypoglycemia Triggered by Liver Injury in Elderly Subjects with Low Body Weight: Case Reports

Learning Points: It is important to classify secondary hypoglycemia and hypoinsulinemic hypoglycemia.Liver injury-induced hypoglycemia is one of the causes of hypoinsulinemic hypoglycemia but rarely observed in everyday clinical practice.Herein, we reported similar 2 cases of hypoinsulinemic hypoglycemia without diabetes presumably triggered by severe liver injury.In both cases, hypoglycemia was improved by glucose infusion, although their liver injury was not improved.We should keep in mind the possibility of hypoinsulinemic hypoglycemia when we examine severe liver injury, especially in elderly subjects with low body weight.
