Understanding Blood Pressure Readings
Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure. Our Blood Pressure Category Checker helps you interpret these two numbers instantly.
The American Heart Association (AHA) and the American College of Cardiology updated their guidelines in 2017 to help people identify high blood pressure earlier. High blood pressure, or hypertension, is known as the "silent killer" because it typically has no obvious symptoms while it causes damage to your heart and circulatory system.
AHA Blood Pressure Categories
| Category | Systolic (mm Hg) | Diastolic (mm Hg) |
|---|---|---|
| Normal | Less than 120 | AND Less than 80 |
| Elevated | 120–129 | AND Less than 80 |
| Hypertension Stage 1 | 130–139 | OR 80–89 |
| Hypertension Stage 2 | 140 or higher | OR 90 or higher |
| Hypertensive Crisis | Higher than 180 | AND/OR Higher than 120 |
Why High Blood Pressure is Dangerous
When your blood pressure is high, your heart has to work harder to pump blood. This can lead to the hardening of the arteries (atherosclerosis) and increase the risk of serious health conditions such as heart attacks, kidney disease, and strokes. Using our BP checker regularly, especially if you have a family history of hypertension, can provide a clear picture of your cardiovascular trend over time.
Managing Your Numbers
The DASH Diet
Dietary Approaches to Stop Hypertension (DASH) is a flexible and balanced eating plan that helps create a heart-healthy eating style for life.
Physical Activity
Aim for at least 150 minutes of moderate-intensity aerobic activity per week to naturally lower blood pressure levels.
