LOPEZ DE FEZ, C.M.; GAZTELU, M.T.; RUBIO, T.  e  CASTANO, A.. Mechanisms of hypertension in obesity. Anales Sis San Navarra [online]. 2004, vol.27, n.2, pp.211-219. ISSN 1137-6627.

Obesity is a chronic disease, considered to be an important risk factor in the development of coronary disease, hypertension, renal insufficiency and failure. Obesity contributes to hypertension by mechanisms such as: insulinic resistance and hyperinsulinaemia, increase of adrenergic activity and of concentrations of aldosterone, retention of sodium and water and increase of cardiac wear, alteration of the endothelial function, through molecules such as leptin and adiponectin and genetic factors. Many paths of research remain open. The angiotensin-converting-enzyme inhibitors (ACEI) and/or the angiotensin II receptor antagonists (ARA II) are first choice medicines because of their beneficial effect on insulinic resistance and sympathetic activity.
