what is the most common cause of secondary hypertension
Secondary hypertension. Secondary hypertension (or, less commonly, inessential hypertension) is a type of hypertension which by definition is caused by an identifiable underlying secondary cause. It is much less common than the other type, called essential hypertension, affecting only 5% of hypertensive patients. It has many different causes including endocrine diseases, kidney diseases, and tumors. It also can be a side effect of many medications.
In middle-aged adults, aldosteronism is the most common secondary cause of hyperten-. sion, and the recommended initial diagnostic test is an aldosterone/. renin ratio. Up to 85 percent of children with hypertension have an. identifiable cause, most often renal parenchymal disease.
