In most people, the specific cause or causes of high blood pressure are not known. This is called primary or essential hypertension. In other people, high blood pressure is the result of another medical problem or medicine. When the cause of high blood pressure is known, this is called secondary high blood pressure or secondary hypertension.
If a person is diagnosed with high blood pressure, it doesn't mean that he or she is "too nervous," overanxious, or obsessive. This is a popular myth. High blood pressure is not nervous tension. In fact, many people who are perfectly calm have high blood pressure.
In addition to lifestyle changes, some people need blood pressure medication to improve their condition. There are many varieties of blood pressure medication; each one works in a slightly different way. People react to medication in different ways, so it's possible that your healthcare provider will need to try a few different types of blood pressure medication to find the one that's best for you.
Hypertension can cause heart attack, stroke or kidney failure
