Abstract
An inhibitor of glucose utilization, 2-deoxy-D-glucose (2-DG) was employed to study the hypothermia of hypoglycemia. After 2-DG infusions, rectal temperatures in normal human subjects fell to nadir levels averaging 1.1°C below base-line values in two to 2.5 hours coincident with maximal increases of plasma growth hormone. Temperatures remained below basal values for six hours in the face of increases in plasma glucose and insulin, and urinary catecholamines. The findings indicate that the hypothermia is conditioned by intracellular glucopenia rather than the availability of circulating glucose or glucoregulatory hormones.
