How To Lower High Blood Pressure
What is high blood pressure?
To understand high blood pressure, you must first know what the tension or hypertension. Briefly, blood pressure is the force exerted by the blood against the artery walls, much like the water pressure in the pipes of a house. If you familiarize yourself first with the functioning of the heart, you will understand more easily the concepts of blood pressure and blood flow.
When it is too high, the blood pressure can damage the walls of arteries. This results in scarring, which can accumulate plates fats, which help narrow the arteries and in the long run to the block. To fight against the resistance created, the heart must work harder and weakens. When blood pressure is high, the blood vessels in the brain may burst, causing a stroke (CVA). Blood pressure varies throughout the day, it goes up or down, often depending on the practiced activity or lack of activity (for example, your blood pressure is usually at its lowest at night, but it rises relatively quickly in the morning at sunrise). It is normal for blood pressure rises occasion, for example, if you’re afraid of something, you are angry or you live a stress.
However, when long remains high, it is probably because you have high blood pressure. Two values are used to measure blood pressure, which can be either systolic or diastolic. Systolic blood pressure is an indication of the pressure within the arteries (the maximum value) when the left ventricle of the heart contracts. For its part, indicates the diastolic pressure in the arteries between heartbeats. Blood pressure in mmHg (millimeters of mercury) is expressed. The following values correspond to different levels of blood pressure:
Normal blood pressure = 120 mmHg or less (systolic) and 80 mmHg or lower (diastolic)
Prehypertensive = 120 -139 mmHg (systolic) or from 80 to 89 mmHg (diastolic)
- Stage 1 = 140 -159 mmHg (systolic) or 90-99 mmHg (diastolic)
- Stage 2 = 160 mmHg or higher (systolic) or 100 mmHg (diastolic)
They say that hypertension is a silent disease because it often causes no symptoms.
That is why it is important to see your doctor regularly.
You’ve probably heard that the heart works like a pump, which is the easiest way to describe this remarkable organ. Your heart is much bigger than your fist – and despite its small size, it pumps about 7,500 gallons of blood to all parts of your body and beats about 100,000 times each day. The role of blood is to transport oxygen and nutrients that the body needs to survive.
Continue our description of the heart. It is in the heart electrical system, emitting small signals brings the walls of the heart to contract. Each contraction pumps blood through the circulatory system. This system, which consists of blood vessels called arteries, capillaries and veins carrying blood to all parts of the body. Heart valves – aortic, pulmonary, mitral and tricuspid – make sure that the blood flows in the right direction. If the heart does not pump properly, blood is not flowing as it should.
The right ventricle pumps blood from the heart to the lungs. With each breath, the oxygen from the lungs into the bloodstream, where it is carried by the blood.
The blood flows through the heart of the following: inside the heart is divided into four parts. The two upper parts are called atria and their role is to collect the blood. Two lower parts, which are the ventricles pump blood away from the heart. The oxygen-rich blood is pumped by the left heart in the arteries when the oxygen is used, what are the veins that return blood to the right heart. This is an ongoing and complex system that performs the pumping and the blood circulation.
What is prehypertension?
We have seen that the characteristic values of the prehypertension range between 120 and 139 mmHg systolic or between 80 and 89 mmHg for diastolic. Instead of using the term prehypertension, some speak rather normal high blood pressure. In Canada, doctors estimate that 2.5 million the number of people who have high normal blood pressure. It is pointed out in the new guidelines for the treatment and management of hypertension up to a million people with high normal blood pressure will really high blood pressure in the next four years, which will increase significantly their risk of heart attack or stroke.
If your normal blood pressure is high, you might direct you to a situation where you need to take medication for the rest of your life. However, if you make changes to your lifestyle, you can take down your blood pressure within safe limits – and if you hold it at this level, many will refer to later risk of making the hypertension.
What are the values of your blood pressure? do not miss not to consult your doctor or pharmacist as soon as you can, in order to check your blood pressure. See other figures that led doctors to worry increasing the care and treatment of hypertension :
- 44% of people do not know the difference between a normal blood pressure and high blood pressure;
- 80% of people do not know that there is a link between high blood pressure and heart disease;
- 63% of people do not believe that hypertension is serious problem , and
- 38% of people think they can treat hypertension without a doctor.
A good way to imagine the blood pressure … When you open a tap, you can see how pressure water flows. Must maintain a certain water pressure in the pipes to prevent them from clogging. However, if the pressure is too high, the pipe can be tested and leaks or other damage may occur. This is the same for the arteries. Excessive pressure may damage them.
Hypertension affects how many people?
More than 5 million Canadians (for example) have high blood pressure.
However, as they often have no symptoms, 42% of them do not even know it. Even among people who know suffering from hypertension, less than a third receive appropriate treatment. These statistics are alarming and this is one of the reasons why it is important to measure your blood pressure regularly. Early detection allows you to get prompt treatment, which reduces the risk to your overall health.
High blood pressure is still the leading cause of death worldwide and the second leading cause of disability after malnutrition in children. In 2000, an estimated 927 million people worldwide were living with high blood pressure, and this number is expected to increase to 1.5 billion by 2025, an increase of about 60%. These figures show how this condition is a challenge, and why it is so important to prevent it, the screen, treat and control.
The increase in the number of people with high blood pressure is related to two factors:
- the aging of the population – blood pressure increases with age;
- the increasing rate of obesity, which is one of the main factors contributing to the development of hypertension and other heart diseases.
