β-Endorphin release in response to recurrent hypoglycemia is implicated in the pathogenesis of hypoglycemia-associated autonomic failure. We hypothesized that exercise-induced β-endorphin release will also result in the deterioration of subsequent hypoglycemia counterregulation and that the counterregulatory response will negatively correlate with the degree of antecedent β-endorphin elevation. Sixteen healthy subjects ...
