Low blood pressure: causes and causes of hypotension

What is low blood pressure? The reasons for this phenomenon lie in the characteristics of the body or hypotension appears for reasons beyond our control? Such questions arise in the head of a person who, at a doctor's appointment, hears for the first time a terrible diagnosis - hypotension. Let's try to understand.

It happens that in the morning you feel fine and ready to conquer the universe, but after a while, the whole fuse somewhere disappears, and you feel tired, feel drowsy and weak. Probably, it's all about reduced pressure, which, contrary to the general error, is just as dangerous as increased pressure.

Low pressure (the causes of this phenomenon will be described below), many doctors consider not a disease, but a feature of the body. However, such an opinion is unlikely to find support among those who have experienced all the "charms" of this state. It is noteworthy that low pressure is the privilege of the female half of humanity.

Normal pressure is considered to be 120 to 80. Moreover, it is important not so much the figures themselves as their ratio, the difference in indices should not exceed 45 units, since then it will be a matter of blood circulation disorders.

At the same time, all the indicators are purely individual, so there are people who throughout their life have a pressure of 100 to 70, but feel great. In this case, it is appropriate to talk about the individual rate. A deviation from the norm (for example, usually the pressure is 120 to 80, and recently - 100 to 70), the body reacts to specific changes and signals a malfunction. It is these phenomena that reveal the essence of the concept of lowering the pressure.

Low pressure (the causes of the phenomenon vary depending on the type) can manifest itself in such forms:

Orthostatic intolerance (OH), when the systolic (upper) and diastolic (lower) pressure are reduced by 20 and 10 units, respectively.

Reduction of this type of pressure is often observed in women under 35 years of age. As a rule, the pressure drops when the person is in the standing position. It manifests itself in dizziness, weakness, pain in the muscles, headache, palpitation, darkening in the eyes, etc.

Orthostatic hypotension (OG), when the pressure decreases by more than 20 to 10.

Reduction of pressure by type of exhaust gas is more often observed in the elderly. The dominant cause can be called a weakly functioning nervous system. When a person rises sharply, the brain lacks oxygen, causing dizziness and fog in front of the eyes.

In addition, we can talk about primary hypotension (so scientifically called reduced pressure) and secondary. The cause of primary hypotension is hereditary predisposition, the causes of the second appear in the process of life (to them can be attributed hepatitis, stomach ulcer, etc.).

The causes of low blood pressure can be much more mundane, that is, do not directly depend on the person. About them and talk.

So, low pressure. Causes

The most common reasons for pressure reduction include climate change (heat, high humidity, radiation). The organism in such periods works in a weakened mode to adapt to new conditions. As a result, the blood condenses, the pressure drops.

Quite often with a decrease in pressure, pregnant women face. The organism of the future mother is being reconstructed to bear the baby, changes in the work of some organs and systems (in particular, the circulatory system). For a child, such a phenomenon is undesirable, since this reduces access to oxygen, in connection with this, it is necessary to normalize the pressure for bearing a healthy baby.

Another reason that can cause a decrease in pressure is dehydration, emotional stress (stress). Therefore, it is reasonable to learn how to react calmly to the occurring phenomena, especially if we can not influence them.

Since the reduction in pressure is the result of a decrease in the vascular tone, one of the most obvious causes is the presence of diseases of the vegetative-vascular system. Therefore, therapists, noting the low pressure in the patient, are advised to visit a cardiologist and prescribe the appropriate treatment.

Low blood pressure is often noted in patients who underwent severe surgeries in the so-called rehabilitation period.

Thyroid hypothyroidism and severe chronic illnesses can also contribute to lowering blood pressure.

Often, women note that the pressure decreases on the eve of menstruation. This phenomenon is quite widespread and, as a rule, does not cause fear, as the pressure quickly returns to the usual indicators.

These are the main causes of low blood pressure in humans. I would like to stress that not so much dangerously low pressure, but a sharp decline in indicators. Especially it concerns the elderly. Therefore, we should not complain about the disease, but, as it is, understand the cause of the malfunction in the body and, if possible, eliminate it.
