Deficient liver function has been assumed in certain cases of spontaneous hypoglycemia, but no proved examples of hepatic origin comparable with those apparently due to hyperinsulinism have been reported. The liver appears to be able to maintain an adequate blood sugar level in spite of widespread injury. Although complete removal is followed experimentally by a progressive fall in blood sugar, no marked change in carbohydrate metabolism has been observed after partial removal.
