Hypertension is one of the widespread diseases of the cardiovascular system and it is expressed in chronic increase of the arterial pressure. This disease is met in more than 50% of cases in people at the age of over 40 years and it affects not only cardiovascular system but also other organs.

Causes of hypertension:
- genetic predisposition
- frequent prolonged stresses
- neuropsychic loads
- age change in the body
- high activity of liver, dysfunction of the bile passages
- unhealthy diet and passive way of life

The symptoms of hypertension have rather acute character and may cause a complete inability of a human being. The most common symptoms of the arterial hypertension are high arterial pressure, poor memory, sleep disorder, high fatigability, apathy, heart pain, rapid heartbeat, and severe edemas on the body.
During this disease pressure drops may be very fast and strong, and therefore a human body does not stand such drops and may lose consciousness.
The treatment of hypertension bears an individual character and depends on the cause of the disease, its character and presence of other dysfunctions of the body.
A non-drug treatment includes diets, physical exercises, and reduction of stresses. However the use of the drugs is the most effective which contain antiedemic action and lower the pressure.
