There is hyperinsulinism as a result of islet cell tumor of the pancreas, the hypoglycemia due to Simmonds' disease of the pituitary, and hypoglycemia due to myxedematous condition of the thyroid. In addition, we have the hypoglycemia due to liver dysfunction, and the functional hypoglycemia which is considered to be on an emotional basis.

In all the previous mentioned hypoglycemias we start with a normal or below-normal fasting blood sugar. The glucose tolerance curve is either flat or below normal with one exception—the glucose tolerance curve of liver dysfunction. In that condition the curve bears a resemblance to a diabetic curve in certain features, but
