- Low blood pressure - can it be considered normal?
- The rate of blood pressure
The rate of blood pressure
Blood pressure is directly related to the vital signs such as heart rate, respiratory rate and heart rate, body temperature. Therefore it is necessary to monitor the magnitude of the pressure, because the deviation from the norm could mean disruption of vital organs. Most high blood pressure is observed at the time of the ejection of blood into the aorta; min - when the blood reaches the vena cava. There are upper (systolic) and lower (diastolic) blood pressure. For example, if the pressures are 120/80, "120" - is the upper systolic pressure, and "80" - the lower the diastolic pressure.
Systolic pressure represents the pressure that occurs when the blood passes through the arteries from the heart to other organs and parts of the body (heart muscles contract). Diastolic blood pressure represents the pressure in the arteries in between heartbeats (cardiac muscle relaxed).
It is considered that the normal pressure is 120/80, but many experts believe that the optimal pressure is 115/75. Overall, realize what is the optimal pressure for a specific person, rather difficult.
Nevertheless, the pressure is below 90 (systolic) and 60 (diastolic) is considered to be low. The pressure may be considered low or even lower if only one parameter is underestimated, i.e. systolic or diastolic. Therefore, the pressure of 115/50 is considered to be low.
Types of low blood pressure
Orthostatic hypotension: a sudden sharp decrease in blood pressure in people who rise sharply after prolonged sitting or lying down. The fact is that when you get up abruptly, the blood rushes to the extremities, resulting heartbeat quickens. However, this compensation mechanism does not work in humans with orthostatic low pressure. They are getting up after a sudden sharp drop in blood pressure, leading to dizziness, loss of coordination and even loss of consciousness.
- Causes of orthostatic hypotension: dehydration, a long stay in lying position (for example, in the treatment of bed rest), pregnancy, burns, diabetes, fever, varicose veins and some neurological diseases. The most common orthostatic hypotension in people older than 65 years, but for young people it is also found.
- Multiple system atrophy with orthostatic hypotension: sometimes low blood pressure caused by the violation of the nervous system. This disease is known as Shy-Drager syndrome (or hereditary mieloentsefalopatiya), developed by the collapse of the autonomous (vegetative) nervous system. Multiple system atrophy untreatable and leads to death of the patient within 7-10 years after diagnosis.
- Postprandial hypotension: In rare cases, a sharp decrease in blood pressure occurs after a meal (by gravity blood rushes to the feet). Our body is "programmed" so that the effect of gravity must be compensated palpitations and vasoconstriction. People with Parkinson's disease often develops postprandial hypotension.
- Vegetovascular hypotension (dystonia): in this case, a sharp drop in pressure occurs after long standing, especially in hot weather. It is caused by a violation of communication between the brain and the heart. When you stand for a long time, the blood rushes to your legs, but the body compensates for this by normalizing blood pressure. But in people suffering from vascular dystonia, the nerves of the left ventricle of the heart sends the brain a signal that the blood pressure is not reduced, but increased. As a result, the heartbeat slows and the pressure is reduced further. This disease is most common in young people.
So if you have low blood pressure and accelerated heart rate, you are in danger. The fact that the tachycardia pumping blood through the vessels more difficult, resulting in reduced blood flow to organs and body parts. When the heart rate exceeds 83 beats per second, you should immediately consult a doctor. But remember that after exercise heart rate increases, and that's fine.
The dangerously low blood pressure
Low blood pressure (hypotension) is often considered the norm, especially when you consider that high blood pressure (hypertension) is more harmful to the heart and circulatory system. Low pressure reduces the likelihood of developing kidney disease and stroke
Stroke - a serious brain injury
Nevertheless, low blood pressure is also associated with certain health risks. By lowering the pressure passage of blood through the blood vessels decreasing blood flow to certain vital organs such as the brain and heart, resulting in dizziness
Dizziness - if the ground is slipping from under his feet
and loss of consciousness.
Age is directly related to blood pressure.
Older people who rise sharply after meals, postprandial hypotension develops. Children and young people often develop vascular dystonia.
The likelihood of hypotension is increased in people with cardiovascular disease and Parkinson's disease

Low blood pressure and pregnancy
Pregnancy often causes a temporary decrease in blood pressure during pregnancy as the circulatory system of women is growing rapidly. According to doctors, in the first 24 weeks of pregnancy, the systolic blood pressure may fall to 5-10 units, and diastolic - 10 - 15 units. As a result, pregnant women often feel dizzy or even faint. By themselves, these displays low pressure has not dangerous but they can cause a drop that already carries the risk for the fetus.
According to some doctors, dehydration can also lead to low blood pressure in pregnant women, therefore, recommended during pregnancy increase the intake of liquids (water or juice).
Treatment of low blood pressure
Low blood pressure usually does not require treatment, especially when it comes to asymptomatic hypotension. Treatment of symptomatic hypotension usually assigned depending on its cause.
To normalize the pressure is often recommended to change the diet, in particular, increase the intake of sodium.
Here are some non-pharmacological means of normalizing blood pressure:
- Limit your caffeine intake
- Increase your fluid intake
- Exercise regularly (to improve blood flow)
- Carefully stand up and lie down on the bed to keep from falling. When you get up, sit down on the bed first, and only then get up on his feet.
- Do not take hot baths. Long-spa treatments are also contraindicated.
