What are the causes of Hypertension?

Primary hypertension

Primary hypertension is the basic anatomy of hypertension or high blood pressure, responsible for approximately 90% of all cases of hypertension. Inward nearly all modern societies, blood pressure rise up with aging and the risk of becoming hypertensive in later life is considerable. 

Life-style factors that bring down blood pressure include reduced dietetic salt intake, increased consumption of fruits and low fat products, exercise, weight loss and reduced alcohol consumption. Stress seems to play a bit part with particular relaxation methods not abided by the evidence. The conceivable role of additional genes such as caffeine consumption, and vitamin D inadequacy are less clear cut. Insulin resistance, which is common in obesity and is an element of  the metabolic syndrome, is also believed to lead to hypertension. Modern studies also concern the consequences in early life as risk elements for adult primary hypertension for low birth weight or maternal smoking or lack of breast feeding, although the mechanisms associating these exposures to adult hypertension remain obscure.

Secondary hypertension

Secondary hypertension consequences by a recognizable cause. Renal disease is the most common secondary cause of hypertension. Hypertension can also be caused by endocrine disciplines, such as Cushing's syndrome, hyperaldosteronism or Conn's syndrome, acromegaly, hyperthyroidism, hyperparathyroidism and pheochromocytoma. Additional causes of secondary hypertension admit obesity, pregnancy, sleep apnea, immoderate licorice consumption, coarctation of the aorta, and certain prescription medicines, herbal remedies and illegal drugs.
