What is (are) High Blood Pressure ?
High blood pressure is a common disease in which blood flows through blood vessels (arteries) at higher than normal pressures. There are two main types of high blood pressure: primary and secondary high blood pressure. Primary, or essential, high blood pressure is the most common type of high blood pressure. This type of high blood pressure tends to develop over years as a person ages. Secondary high blood pressure is caused by another medical condition or use of certain medicines. This type usually resolves after the cause is treated or removed.
