The most common cause of secondary arterial hypertension is

A. adrenal cortical tumors
B. adrenal medullary tumors
C. diffuse renal disease
D. pituitary diseases
E. liver disease


C
Even though 90% of all hypertension is idiopathic (i.e., primary), most of those classified as secondary are caused by renal disease. Renal diseases cause increased release of renin, which acts on angiotensinogen to convert it into angiotensin I and II. Angiotensin II acts on the adrenal cortex, stimulating the secretion of aldosterone, but it also causes hypertension by stimulating the contraction of arterioles.
