If the measurement of your blood pressure indicates high blood pressure, it means that your heart is making more effort than it should to pump blood and your arteries are under pressure.
This situation is dangerous.
In fact, if you do nothing to lower blood pressure, increases the risk of stroke, heart attack , kidney disease and other deadly diseases.
Half the people who suffer from high blood pressure do not know they resent.
An examination of the blood pressure is a great protective and preventive measures that we can do to our body, in fact allows for the immediate control of the circulatory system.
Many fear that high blood pressure prelude to disability and premature death.
In the circulatory system, the heart and arteries need to maintain a given pressure to push blood through the vessels that go hand in hand shrinking: from the arteries to arterioles and capillaries from these.
Without that blood pressure could not feed the billions of hungry cells of the body.
Dozens of times a day the pressure is subject to large fluctuations to meet the needs of the organism.
Generally, for the blood pressure monitor: inflating the cuff, the doctor pressed against the main artery of the arm bone, to stop the circulation of blood when listening with the stethoscope, hear the heartbeat stop, it begins to deflate slowly the sleeve.
If they finds blood pressure at the instant when the pulse starts to pulsate.
This is the systolic pressure, ie the maximum pressure in the arteries when the heart contracts.By continuing to deflate the cuff, the doctor makes a second reading when the pulse disappears again when the heart, for a small fraction of the time, rest.This is the diastolic pressure, ie the minimum pressure in the arteries between beats and the other of the heart.
Few doctors trust a single test.
Many factors can lead to incorrect index of high pressure, even the anxiety caused from the examination itself.
Usually we tend to do several tests, taking into account the lower figures.
It 's the lower pressure, diastolic blood pressure that can probably affect more than the systolic.
In fact reveals the effort which is subject to the heart between beats and the other, when it should take that rest is vital.
In a sense you can think of diastolic blood pressure as a measure of quality of rest that is given to the heart.
In moments of anger, adrenaline contracts the arteries, causing increased pressure, as in a those when it is pressing in this way the body receives a fresh supply of energy to meet a critical condition.
Another controller is the carotid sinus in the neck, a slight swelling main artery that carries blood to the head.
When this small bag inflates too much blood, his nerves send a message to the brain, which responds by ordering the muscles of the walls of the arteries to relax and the heart to slow down, thus lowering the pressure.
| Blood pressure (mm Hg) | Normal values | Limit values | High Blood Pressure |
| systolic = higher value | up to 140 | 141-160 | over 160 |
| diastolic = lower value | up to 90 | 91-95 | over 95 |
In 'essential hypertension blood pressure is too high.
Some symptoms of hypertension include: chronic headaches, palpitations, shortness of breath, fatigue, nosebleeds, blurred vision, flushed face, frequent urination, ringing in the ears.
Tension and various efforts, constant anxiety and fatigue can contract the artery walls and to increase the pressure, if the force or tension persists, the pressure is maintained at a high level, imposing a burden on the heart and arteries.
Often the heart expands to cope with more work.
The arteries lose their normal elasticity and harden.
If nothing is done, the heart may fail by excessive work, can form a clot that blocks blood or corroded artery can rupture in the brain.
Hypertension, if not corrected, increases the thickness of the heart muscle at risk of heart failure.
Hypertension upsets the structure of the arteries of the heart (with risk of angina and myocardial infarction), brain (risk of stroke), retinal (reduction of vision), kidney (renal failure).
Sometimes the examination of blood pressure gives lower figures than usual.
People often complain of fatigue that are affected but the low blood pressure predisposes to a long and healthy life.
No one should fear the cuff to measure pressure, we can even say that is one of our best friends.
There is a curious German research published in the Journal of the American Medical Association which states that the polyphenols in chocolate (dark) help dilate blood vessels.
A little more than 6g a day in 4 months have reduced the pressure so that 18% of patients did not suffer more hypertension.
By controlling the pressure levels reduces the risk of suffering from arrhythmia.
An alarm signal for this kind of problem is the sharp drop in resistance during cardiovascular workouts.
