Causes of Hypertension
# Primary Hypertension
About 95% of adults with high blood pressure have primary hypertension (sometimes called essential hypertension).
The cause of primary hypertension is not known,although genetic and environmental factors that affect blood pressure regulation are now being studied.
Environmental factors include excess intake of salt,obesity,and perhaps sedentary lifestyle.
Some genetically related factors could include inappropriately high activity of the renin‐angiotensin‐aldosterone system and the sympathetic nervous system and susceptibility to the effects of dietary salt on blood pressure.
Another common cause of hypertension is stiffening of the aorta with increasing age. This causes hypertension referred to as isolated or predominant systolic hypertension characterized by high systolic pressures (often with normal diastolic pressures),which are found primarily in elderly people.
# Secondary Hypertension
This pertains to the relatively small number of cases,about 5% of all hypertension,where the cause of the high blood pressure can be identified and sometimes treated.
The main types of secondary hypertension are chronic kidney disease,renal artery stenosis,excessive aldosterone secretion,pheochromocytoma,and sleep apnea.
A simple screening approach for identifying secondary hypertension is given later.","department":"
