The Basics
Starting at age 18, you should check your blood pressure at least every 2 years. It is important to check your blood pressure often, especially if you are over 40 years old.
High blood pressure has no signs or symptoms. The only way to know if you have high blood pressure is to get tested.
What Happens When you Test Your Blood Pressure?
To test your blood pressure, the doctor or machine will put a cuff over your upper arm and squeeze it. It only takes a few seconds.
