Abstract
An 85-year-old woman was admitted to our hospital because of hypoglycemia and impairment of consciousness several hours after breakfast. Because the hypoglycemia predominantly occurred 2–4 h after meals, we diagnosed reactive hypoglycemia. An oral glucose tolerance test showed prolonged hyperinsulinemia following the postprandial hyperglycemia, with a subsequent rapid decrease in blood glucose concentration. The post-stimulus plasma C-peptide concentration was relatively low compared to the plasma insulin concentration. Abdominal computed tomography revealed an intrahepatic congenital portosystemic shunt (CPSS). On the basis of these findings, we concluded that the reactive hypoglycemia was induced by the CPSS, via a reduction in hepatic insulin extraction. Treatment with an alpha-glucosidase inhibitor resolved the reactive hypoglycemia. CPSS comprises anomalous vascular connections between the portal vein and the systemic venous circulation, and reactive hypoglycemia is a rare complication of this malformation, which has most frequently been reported in children, with only a few cases reported in adults. However, this case indicates that even in adult patients, imaging studies should be conducted to rule out CPSS as the cause of the reactive hyperglycemia.
