title: [Endothelial function].
abstract: It is well known that diabetes mellitus often combines with hypertension. Diabetes mellitus is associated with endothelial dysfunction. An imbalance of reduced production of nitric oxide or increased production of reactive oxygen species, mainly superoxide, may promote endothelial dysfunction. One mechanism by which endothelium-dependent vasodilation is impaired is an increase in the oxidative stress that inactivates nitric oxide. Both high glucose and insulin resistance reduce the bioavailability of nitric oxide through an increase in oxidative stress. It is unclear that endothelial dysfunction is a cause or consequence of hypertension. In this review, we present the possibility that endothelial dysfunction causes hypertension in diabetes mellitus.
