**Abstract**

Responsibility for the dysfunction of the autonomic nervous system in the genesis or aggravation of cardiovascular and/or metabolic disorders is currently held. Indeed, a significant correlation between sympathetic overactivity and the pathophysiological mechanisms responsible for type 2 diabetes has been proven. Therefore, the treatment of this dysautonomia could improve the management of type 2 diabetes.
