What is low blood pressure?The causes of 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 feeland are ready to conquer the universe, but after a while, the whole fuse 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 bedescribed below), many physicians 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 "delights" of this state. It is noteworthy that low pressure is the privilege of the female half of humanity.
The normal pressure is 120 to 80.Moreover, it is important not so much the figures themselves as their ratio, the difference in indicators should not exceed 45 units, since then it will be a matter of blood circulation disorders.
At the same time, all indicators are strictly 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 responds 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 pressure of this type is often observed inwomen who are under 35 years of age. As a rule, the pressure drops when the person is in a 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 is reduced by more than 20 to 10.
Reduction of pressure by type of exhaust gas is more often observed inold people. 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 vital activity (to them can be attributed hepatitis, stomach ulcer, etc.).
The causes of low blood pressure can be much more mundane, that is, not directly dependent on a person. About them and talk.
So, low pressure. Causes
The most common reasons for the declinepressure can be attributed to the change in climatic conditions (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 they collide with a decrease in pressurepregnant women. 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 decreasepressure - it's dehydration, emotional stress (stress). Therefore, it is reasonable to learn how to react calmly to occurring phenomena, especially if we can not influence them.
Since the decrease in pressure is the result of a decreasethe tone of the vessels, then one of the most obvious reasons is the presence of diseases of the vegetative-vascular system. Therefore, therapists, noting the low pressure in the patient, are advised to visit the cardiologist and prescribe the appropriate treatment.
Low blood pressure is often noted in patients undergoing heavy surgery 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 decreasesin anticipation 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 pressure inrights. I would like to emphasize that not so much dangerously low pressure, but a sharp decline in indicators. This is especially true of older people. Therefore, you should not complain about the disease, but, if it is, understand the cause of the malfunction in the body and, if possible, eliminate it.
