Know Your Numbers: Understanding BloodPressure

Blood pressure is one of the most important numbers to know about your health. High blood pressure often causes no symptoms, yet over time it can damage the heart, blood vessels, kidneys, brain, and other organs.

Understanding Your Blood Pressure Numbers

A blood pressure reading has two numbers. The systolic pressure, or top number, measures pressure in the arteries when the heart contracts. The diastolic pressure, or bottom number, measures pressure when the heart relaxes between beats.

Current adult blood pressure categories are:

• Normal: less than 120 systolic AND less than 80 diastolic.

• Elevated: 120–129 systolic AND less than 80 diastolic.

• Stage 1 hypertension: 130–139 systolic OR 80–89 diastolic.

• Stage 2 hypertension: 140 or higher systolic OR 90 or higher diastolic.

A single elevated reading does not necessarily establish a diagnosis. Blood pressure should be measured accurately and interpreted in the context of repeated readings and your overall health.

What You Can Do Today

• Know your numbers and have your blood pressure checked regularly.

• If you monitor at home, use a validated upper-arm cuff that fits properly.

• Sit quietly before measuring, keep both feet on the floor, support your back, and keep your arm supported at heart level.

• Maintain a healthy weight and stay physically active.

• Choose a heart-healthy eating pattern and reduce excess sodium.

• Take prescribed blood pressure medications consistently and discuss concerns with your healthcare provider rather than stopping them on your own.

When Should You Seek Medical Attention?

If your blood pressure is higher than 180/120 mm Hg and you have symptoms such as chest pain, shortness of breath, weakness, numbness, vision changes, difficulty speaking, or other concerning symptoms, seek emergency medical care.

Blood pressure is more than a number on a chart. Knowing your usual readings and making small, consistent lifestyle changes can help you recognize problems earlier and protect your long-term health.
