The Basics: Overview
One in 3 American adults have high blood pressure. High blood pressure increases your risk for serious health problems, including stroke and heart attack.
Get your blood pressure checked regularly starting at age 18 – and do your best to keep track of your blood pressure numbers.
How often do I need to get my blood pressure checked?
- If you are age 40 or older, or if you are at higher risk for high blood pressure, get your blood pressure checked once a year.
- If you are age 18 to 40 and you aren’t at higher risk for high blood pressure, get your blood pressure checked every 3 to 5 years.
What puts me at higher risk for high blood pressure?
Your risk for high blood pressure goes up as you get older. You are also at higher risk for high blood pressure if you:
- Are African American
- Are overweight or obese
- Have blood pressure higher than normal
- Don’t get enough physical activity
- Drink too much alcohol
- Don’t eat a healthy diet
- Have kidney failure, diabetes, or some types of heart disease

What is blood pressure?
Blood pressure is how hard your blood pushes against the walls of your arteries when your heart pumps blood. Arteries are the tubes that carry blood away from your heart. Every time your heart beats, it pumps blood through your arteries to the rest of your body.
What is hypertension?
Hypertension (“hy-puhr-TEHN-shun”) is the medical term for high blood pressure. High blood pressure usually has no symptoms, so it’s sometimes called a “silent killer.” The only way to know if you have high blood pressure is to get tested.
The Basics: How It's Measured
What do blood pressure numbers mean?
A blood pressure test measures how hard your heart is working to pump blood through your body.
Blood pressure is measured with 2 numbers. The first number is the pressure in your arteries when your heart beats. The second number is the pressure in your arteries between beats, when your heart relaxes.
Compare your blood pressure to these numbers:
- Normal blood pressure is lower than 120/80 (said “120 over 80”).
- High blood pressure is 140/90 or higher.
- Blood pressure that’s between normal and high (for example, 130/85) is called elevated blood pressure or prehypertension (“PREE-hy-puhr-tehn-shun”).
How can I get my blood pressure checked?
To test your blood pressure, a nurse or doctor will put a cuff around your upper arm. The cuff will be pumped with air until it feels tight, then the air will be slowly let out. This won't take more than a few minutes.
The nurse or doctor can tell you what your blood pressure numbers are right after the test is over. If the test shows that your blood pressure is high, ask the doctor what to do next.
Blood pressure can go up and down, so you may need to get it checked it more than once.
Can I check my blood pressure by myself?
Yes. Many shopping malls, pharmacies, and grocery stores have blood pressure machines you can use in the store. You can also buy a home blood pressure monitor at a drug store. If the test shows that your blood pressure is high, talk to a doctor.

How can high blood pressure affect pregnancy?
High blood pressure can be dangerous for a pregnant woman and her unborn baby. If you have high blood pressure and you want to get pregnant, it’s important to take steps to lower your blood pressure first.
Sometimes, women get high blood pressure for the first time during pregnancy. This is called gestational (“jes-TAY-shon-al”) hypertension. Usually, this type of high blood pressure goes away after the baby is born.
If you have high blood pressure while you are pregnant, be sure to visit your doctor regularly.
