Blood pressure is basically a measurement of how hard our hearts have to work to pump blood around our bodies to keep us alive. High blood pressure can have a variety of causes, although there are several that are more prominent and consistent with the condition. Very high blood pressure is known medically as hypertension and will mean a lifetime prescription in most cases to artificially lower the pressure, which will cut the risk of heart attacks and strokes. Anticoagulants are what is usually prescribed unless surgery is required, which mean drugs that thin out the blood making it easier to pump. The doctors will also of course recommend a course of life changes including more exercise and a low sodium (salt) diet, as well as weight loss in most cases.
High blood pressure is very often caused by being overweight or obese, meaning it is more likely that you will have high cholesterol as well which can encrust the arteries, meaning the pressure to pump the same amount of blood is raised. If the arteries become too clogged then surgery is often required where the section is removed and replaced by a section of large vein from the leg. Having high blood pressure can put you at higher risk of heart disease, heart attacks and strokes, as well as dizziness and fainting.
There are some genetic predispositions that can make it more likely that you will suffer from hypertension and high blood pressure however. There is a high instance of hypertension in men from the afro-Caribbean countries, even though they may not be overweight or seemingly have any other conditions which are predispositions to hypertension. It is also hereditary to a degree, meaning that if there is a story of high blood pressure and or heart attacks in the family, then it is quite likely that you will suffer as well. Being diabetic and having high stress levels are also both triggers in a lot of cases.
Although potentially deadly and often undetectable unless tested for because if has no outward symptoms, there are ways to combat high blood pressure and hypertension. The best way is to try to lead a more healthy lifestyle and lose weight, as well as eating a diet containing less sodium and cholesterol and getting more exercise. Medications such as warferin are also used, and believe it or not common aspirin is another of these type of drugs, albeit a weaker one, which is why it is recommended that older people take one per day to help cut the risk of heart attacks and strokes.
