Physiological and metabolic responses to brief stress in non-insulin dependent diabetic and control subjects.

Eight non-insulin dependent diabetic subjects and eight controls were studied during physical and psychological stress. Physiological measures of heart rate, finger pulse amplitude and blood pressure, as well as metabolic measures of blood glucose, insulin, catecholamines and glucagon were sampled during the experiment. Results indicate substantial physiological arousal during the tasks for both groups, but no changes in blood glucose. Despite signs of mild autonomic neuropathy, the diabetic subjects showed responses similar to the controls on the stress tasks. Overall, this study suggests that diabetic instability does not necessarily follow from physiological activity and stress hormone elevations.
