Blood pressure is the pressure that blood exerts on the walls of blood vessels. The magnitude of blood pressure depends on the resistance of the walls of blood vessels, the contraction force of the heart, the amount of blood. The pressure deviation from the norm, more or less, some do not consider the disease, if all the other organs and functions in the body are working normally. But some experts think that low blood pressure may even in some cases be a threat to human life.
Usually if you have low blood pressure felt nausea, dizziness, loss of coordination, balance, pallor, frequent palpitations, shortness of breath.
Normal blood pressure
Blood pressure is an indicator that you need to constantly monitor. As it depends on the frequency of respiration, pulse and heartbeat, abnormalities indicate malfunction of vital organs. The blood pressure is not constant. Distinguish between upper (systolic) pressure is the pressure that occurs when the ejection of blood into the aorta, and the lower (diastolic) is the pressure at a time when the blood reaches the veins cava.
Systolic pressure is the pressure of blood in its passage through the arteries from the heart to other organs (heart beats). Diastolic pressure – the pressure of blood when heart is relaxed, i.e. in the intervals between heartbeats.
It is usually assumed that the normal pressure is 120/80, although some experts argue that the most comfortable pressure 115/75. Actually normal pressure for each person individually and it is difficult to determine with great precision.
However, the pressure 90/60 is considered low. Moreover, a reduced pressure is considered, even if not understated both indicators (upper and lower), and at least one. Therefore, the testimony 110/50 also considered reduced.
Symptoms of blood pressure 100/50
- Lethargy, drowsiness, fatigue, passing in the destruction. Even minor physical or mental work leads to exhaustion, and relief does not bring rest, sleep;
- Headache; headache under reduced pressure usually covers the temporal and occipital parts. By its characteristics headache under reduced pressure similar to migraines. The pain may be dull, monotonous or pulsed. Often accompanied by nausea and vomiting
- Dizziness that can cause gait changes, cause of syncope.
- Irritability, tearfulness.
Symptoms at low pressure is the body’s inability to adapt to changing environmental conditions. Usually hypotonic crisis (a sharp decrease in pressure) can cause finding in a hot, stuffy environment; when alcohol.
Types of low blood pressure
Orthostatic hypotension – a sudden drop in blood pressure when sudden getting up after lying or sitting. When the man abruptly stands up, the blood rushes to the extremities. Normal this should increase the heartbeat. However, in people with orthostatic low blood pressure this does not occur, whereby the pressure is dramatically reduced and can cause sudden bouts of dizziness, weakness, loss of coordination, and even consciousness. This condition can be caused by pregnancy, diabetes, burns, prolonged bed regime, dehydration, neurological diseases. Most often orthostatic hypotension is common in older people over 65 years of age, but sometimes she can be and young people.
Postprandial hypotension – decreased pressure after eating. Thanks to gravity, the blood rushes to the feet. This is supposed to increase the heart rate and constricts blood vessels to compensate for the effects of gravity.
Vegetative-vascular hypotension (dystonia) — pressure reduction after long standing, often in hot weather. Occurs because of disturbances of the connections between the brain and the heart. If the person is a long time, the blood rushes to the feet, and normal, to compensate, blood pressure normalizes. However, people who suffer from vascular dystonia, from the heart to the brain the signal that the pressure is not reduced, but rather increased. This slows the heartbeat, and even less pressure. This disease often occurs in young people.
If the pulse is frequent, and the pressure is low, this is a dangerous condition. Because when the frequency of the pulse pumping of blood through the vessels is impeded, and this leads to the fact that decreases blood flow to organs and body parts. If the pulse exceeds 83 beats per minute, and you have not experienced increased physical activity is the reason for going to the doctor.
Low lower blood pressure
The lower the pressure that fixes the tonometer, is manifested in the time of relaxation of the heart muscle. Harmonious is this lower pressure, when its performance is less than the upper 60-70 mmHg. In other words, if the optimal upper blood pressure is the number of 120 mmHg, the bottom should be — 80 mmHg. If the latter figure is much less, talk about low pressure.
Its symptoms often are lethargy, drowsiness, weakness, dizziness, nausea, irritability, or tearfulness.
The reasons for such a state of lower pressure can be:
- Renal or heart failure, is recognized as the most common cause of low low pressure;
- Cardio-vascular dystonia;
- Overactive thyroid glands.
To increase excessively low bottom pressure, you need by cause of the disease, to eliminate it.
In addition, normalization of lower pressure should lead a healthy way of life, spending more time in the fresh air, giving the body the moderate exercise. Don’t forget that to change the situation required an 8 – hour night sleep. If possible, make yourself a small Siesta.
Many are beginning to use sedatives, but you should do so only on doctor’s prescription. This treatment is suitable only for people suffering from lower low and a little high top pressure.
Low top blood pressure
The upper pressure is the force that acts on the vascular wall at the moment of tension of the heart muscle. Upper pressure helps to determine the force with which the heart pumps blood. Traditionally, the norm is the indicator of the upper pressure 110 — 120 mm. Hg.
The top reasons for low pressure can be:
- Bradycardia, that is, acceleration of heart rate;
- malfunctioning heart valve
- Pregnancy. Usually in the first trimester, there is a low upper pressure;
If one of the indicators (upper or lower pressure) below the norm, it is considered that the person suffers from hypotension, meaning low blood pressure. However, the alarm must cause a decrease systematic, distracting. Isolated cases of pressure reduction can be caused by changes in climatic conditions, mental or physical stress.
What is dangerous blood pressure 100 / 50
Generally low pressure less dangerous than high. At low pressure reduces the risk of stroke and kidney disease. However, low blood pressure is dangerous because it decreases the blood flow to the brain and heart, and this can lead to dizziness and loss of consciousness.
At different ages often have different types of hypotension. In the elderly, with a sharp rise after eating develops postprandial hypotension. Youth and children may develop vegetative-vascular dystonia.
Greater risk of developing hypotension-prone people suffering from Parkinson’s and cardiovascular diseases.
Low blood pressure and pregnancy
During pregnancy low blood pressure is caused when the circulatory system of a pregnant woman is growing rapidly. Therefore, in the first 24 weeks of pregnancy top sometimes reduced pressure by 5-10 units, and the lower by 10-15 units. By itself, this reduction is not dangerous, but may experience loss of consciousness, and this can lead to a drop that is dangerous to the fetus. One of the reasons for lowering the pressure in pregnant women dehydration. Therefore, when pregnancy is recommended to drink plenty of liquids.
Treatment of low blood pressure
Usually, asymptomatic hypotension is not treated. Symptomatic hypotension is treated depending on what the causes are caused.
The pressure returned to normal, you can change the diet, to increase the content of dietary sodium, reduce your caffeine intake, increase your fluid intake. Do not allow sharp stevani. To get out of bed, first sit down, and then gently climb. Get regular exercise to improve blood flow. Do not take a long Spa treatments and hot tubs.
