Blood pressure 120/80 is the ideal average for a person. Many are faced with the problem of deviating pressure from the norm. Its increase is called hypertension, with indicators below the norm, they speak of hypotension.

The pressure of circulating blood on the vascular walls is called arterial. Distinguish between systolic and diastolic pressure. Systolic pressure on the walls of the artery is created when the heart contracts, and diastolic pressure at the time of the expansion of the heart when blood enters it.

Systolic pressure is also called upper, and diastolic pressure is called lower.

Normally, a healthy adult has an upper pressure of 120 mm Hg. Art., 80 - lower. The difference between them is called pulse pressure. It makes blood circulate throughout the body. If a person has pressure deviations from the norm, then this may indicate the presence of certain diseases.

Symptoms and causes of hypertension

Hypertension is a pathological condition. It is caused by high blood pressure.

During hypertension, vasoconstriction is observed, which leads to difficulty in blood flow, the heart has to expend enormous resources in order to push it through. This increases the pressure on the vessel walls.

With an easy stage of the disease, the pressure fluctuates between 160/190. This stage is characterized by a periodic increase in blood pressure to a given level.

The moderate (second) stage is characterized by a persistent, long-term pressure increase up to 180/100.

And the most dangerous third stage is characterized by constant pressure over 180/100. The pressure does not fall below this threshold.

Stress of varying intensity, malnutrition, insufficient fluid intake, physical inactivity, hereditary predisposition, diabetes, diselementosis (washing out of potassium and magnesium with increased use of table salt) can lead to the occurrence of a state of hypertension.

Symptoms and causes of hypotension

The main signs of the disease include a permanent or temporary drop in blood pressure. The patient may experience: decreased memory and performance, mood swings, irritability, decreased concentration, distraction, withdrawal, poor sleep, nausea, dizziness, digestive disorders, shortness of breath, decreased sexual activity in men, in women - early onset of menopause.

Hypotension can be caused by neuroses, constant fatigue, periodic lack of sleep, depression, psychological trauma. In childhood and adolescence, this condition may be a sign of vegetative-vascular dystonia.
