High blood pressure involves a great many older people. It is believed that 15 to 20 percent of all deaths in the United States in people over fifty years of age are due to high blood pressure! First of all, what is blood pressure? It is the amount of pressure exerted on the blood by the heart and the arteries. When the left ventricle of the heart contracts, it forces blood out into the arteries. The major arteries then have to expand to receive the blood. But the muscular lining of the arteries resists this pressure, so the blood is squeezed out into the smaller blood vessels of the body. So blood pressure is the amount of pressure the blood is under as a result of the pumping of the heart and the resistance of the walls of the arteries.
There is a way of measuring this, and a certain amount is considered normal for a person’s age. But in some people, this pressure becomes greater than normal, and it is then called “hypertension ”, or high blood pressure.
It can be caused by many things, such as nervous tension and disturbances of glands or the kidneys. Usually, it is difficult to know all the reasons. And in most cases, a person can have it without any unpleasant symptoms. In some cases, the condition quickly becomes worse.
What is happening is that the smaller blood vessels of the circulatory system are resisting the flow of blood. Then certain symptoms may appear. There could be heart palpitations, headaches, dizziness, and a feeling of being tired.
Medicine has many ways of treating this condition, depending on the specific case. This ranges from rest, change of job, diet to lose weight, low salt diet, surgery, and so on.
