Asymptomatic hypoglycemia in IDDM patients seems to be more frequent during the night than during the day, with reported frequencies as high as 56%. Hormonal counterregulation to diurnal and nocturnal hypoglycemia was studied in 10 insulin-dependent diabetic patients without diabetic complications in order to test whether hormonal responses were lower at night than during daytime. A lower catecholamine response might imply less marked symptoms and therefore one reason why patients are not awakened by hypoglycemia. Blood glucose was stabilized to around 6 mmol/1 by iv insulin infusion and hypoglycemia was induced by increasing the insulin infusion rate—in the night studies at 01.30, in the day studies at 08.00. Blood glucose nadirs were 1.5±0.4 (1.2–1.9) mmol/1 at night and 1.9±0.3 (1.3–2.2) mmol/l during the day; in three patients the nadirs were identical during both the night and day. One patient had no adrenaline response to daytime hypoglycemia. In general, nocturnal hypoglycemia elicited greater catecholamine responses correlated to the duration of hypoglycemia. Glucagon responses showed a great heterogeneity independently of diabetes duration and hypoglycemic level. Growth hormone secretion was reduced during the night study; however, no refractory periods were found after sleep-related growth hormone secretion. In conclusion: counter-regulatory hormonal responses tend to be greater at night than during the day and do not explain why patients are not awakened by nocturnal hypoglycemia.

ABSTRACT The effect of insulin therapy on growth hormone secretion was studied in five newly diagnosed young insulin-dependent diabetic men. All showed a markedly abnormal pattern of secretion immediately prior to insulin therapy and following "normalization" of the blood glucose there was a significant fall in plasma growth hormone levels after a period of one to two months though these were still considerably elevated above the normal control range. These findings lend support to the view that the abnormal growth hormone secretion observed in diabetes may be the consequence rather than the cause of the disordered carbohydrate metabolism.
