Effect of an extra intake of carbohydrate at dinner on morning after fasting plasma glucose values in types I and II diabetes

Abstract

After a largely enriched meal containing a considerable amount of carbohydrate taken at 1900 the fasting plasma glucose concentration at 0800 the next day was slightly but significantly higher in patients with type I diabetes but not in those with type II disease. The deterioration in type I was not accompanied by symptoms and in most cases was of little importance. Though such an extra load of carbohydrate may have a deleterious effect on postprandial blood glucose control in patients with type II or type I diabetes, and therefore should be avoided (unless they are lean and adjust their insulin accordingly), the excess cannot be detected from the fasting blood glucose value next morning.
