Blood pressure is measured in two numbers:
|
|
= The force of blood when the heart beats (systolic)
= The force of blood when the heart relaxes (diastolic) |
|
(Your doctor will say “120 over 80.”)
|
Both numbers are important. But, as you get older, the top number becomes more important. Treatment usually focuses on lowering the top number.
Getting both numbers down and under control will greatly reduce your risk for problems from high blood pressure. Some of these are:
- Heart attacks
- Strokes
- Kidney disease
- Blindness
Know what each number means. Work with your doctor to reach your target goal.
Normal blood pressure is less than 120/80. Blood pressure of 140/90 and above is high. You have high blood pressure if it measures at least 140/90 in two readings taken at two or more office visits.
About prehypertension
What if your blood pressure is between 120/80 and 139/89? Doctors used to think these numbers weren’t a health risk. They may have called this “borderline hypertension.” But guidelines now call this range “prehypertension.”
If you have prehypertension, you’re AT RISK for having high blood pressure in the future. It means you need to make some lifestyle changes to keep your blood pressure from getting worse.
If you have high blood pressure, your doctor will probably tell you to make lifestyle changes AND take medicine to keep your blood pressure under control.
Different people, different goals
Blood pressure goals tell us what the ideal blood pressure is for most people. But they may not be right for everyone. Your doctor will work with you to set your blood pressure goal.
“White-coat” hypertension
Some people get very nervous at the doctor’s office. This can cause blood pressure to go up for a short time. This is sometimes called “white-coat hypertension.” That’s because doctors often wear white coats.
If your blood pressure is high when it’s checked and you think it’s because you’re nervous, ask to have it checked again after you sit for a few minutes. If going to the doctor makes you nervous, take someone with you for support.
Your doctor or nurse may suggest that you buy a blood pressure monitor and take readings yourself. If you have “white-coat hypertension,” taking your blood pressure at home may solve the problem.
