The mechanism underlying the development of obesity associated hypertension is as follows: (1) physical compression of the kidneys by intrarenal fat and extracellular matrix; (2) impairment of pressure natriuresis; (3) renin–angiotensin system (RAS) activation; (4) increase in the activity of sympathetic nervous system; (5) insulin resistance; and (6) leptin, and other neuropeptide dysregulation [2, 3]. This evidence concerns the gene REN and Hypertension.
