Sudden drop in blood pressure (doctors call it even arterial hypotension) is a condition in which blood pressure falls below 100/60 mm Hg. Art. in men and below 95/60 mm Hg. By man it my drop more below 105/65 mm Hg. already considered to be low.

Thus, depending on the individual low blood pressure may completely disturb. For hypotensive sensitive to pressure drop, increasing it to 130/90 mm Hg.  May be accompanied by symptoms of hypertensive crisis.

Even a healthy person during the day there are significant pressure fluctuations, but the body normally works quickly brings the pressure in the order. Not necessarily be a sign of low blood pressure of ill health. There is also a so-called physiological hypotension. In this case, against the background of low blood pressure a person feels fine, his normal performance, no complaints. Most often this occurs in athletes who trained individuals, whose bodies are used to carry heavy loads. At the same time he begins to work in a more economical mode: reduced heart rate, lowers blood pressure.

Low pressure can be hereditary feature, which is passed from parents. At the same time in many years of work in conditions of reduced pressure the body has adapted to this state, its organs and systems of work in these conditions is normal. No complaints on the health of a person do not, and he may not even suspect that he has low blood pressure.

The residents of certain geographic areas of low pressure are an adaptive response to specific climatic conditions. So, in the highlands, where the atmospheric pressure is different from the normal, the majority of local residents revealed low blood pressure. In tropical countries in hot climates, low blood pressure is a variant of the rules and ensures the normal operation of the organism.

As in the case of high blood pressure, low blood pressure may be a symptom of some other diseases. In this case, symptomatic low blood pressure may be acute or chronic.

By analogy with hypertension can be identified hypotension. Doctors refer to this group of people suffering from neuron circulatory dystonia of hypotonic type.

Risk factors for hypotension.

Often prone to low blood pressure is inherited from parents who have suffered from this disease. In most cases, this problem concerns the female sex. Tendency to low blood pressure are usually observed in childhood. These children are sluggish, lethargic, tired quickly in games with their peers.

In adolescence, when the body is exposed to the most powerful adjustment, low blood pressure occurs as an indicator of imperfect adaptation of the autonomic nervous system in conditions of hormonal changes and rapid growth of the organism teenager.

For hypotensive adults-characterized so-called asthenic constitution - high growth and low weight. Most of them are lean people with pale skin.
