The voltage blood
The blood pressure extent pressure of blood in the arteries. Two figures express. The first, highest, is called the systolic pressure and corresponds to the pressure when heart contracts, is empty and sends blood into the circuit. The second (diastolic pressure), still lower, indicating the pressure when the heart relaxes and fills with blood. Example: 12 / 8.

Hypertension (HTA) is defined from a blood pressure than 16 / 9,5. But considering the hypertension "limits" blood pressure between 14 and 16, as equally dangerous, they also reduce life expectancy. However patches are made with age: it is quite normal, from 70 years as blood pressure rises a little.

Hypertension
In 90% cases, the hypertension is called "essential", that is to say that it is permanent. Otherwise, it is of hypertension paroxysmal or outbreaks of voltage high at times. Anyway, that's not good.

Hypertension usually starts around 20 / 25 years. Its severity and frequency increases with age.

Hypertension is often ignored for a long time because it is manifested by any particular disorder and moreover, it does not hurt.

If undiagnosed and therefore untreated, pressure it has continuously on the arteries eventually deteriorate. Breathlessness, chest pain, headache, dizziness, ringing in the ears, like seeing flies fly are the consequences when alert.

Origins of Hypertension
Many factors led to the hypertension which often combine. Heredity tops. In addition, the obesity the smoking, hypercholesterolemia, hyperuricemia, the diabetes the pill, excessive salt the excessive consumption of licorice and permanent, physical inactivity, age and pregnancy.

If there is a family where the hypertension is frequent, it has an interest in curbing the salt, to endorse the mediterranean diet, not gain weight not to smoke and have a lifestyle with impeccable regular physical activity in order to prevent this disease.
