Check your blood pressure category based on AHA guidelines
Blood pressure is measured in millimeters of mercury (mmHg) and recorded as two numbers: systolic pressure (when the heart beats) over diastolic pressure (when the heart rests). The calculator compares your readings against established medical guidelines from the American Heart Association.
High blood pressure (hypertension) is a major risk factor for heart disease, stroke, and kidney problems. Regular monitoring helps detect issues early and track the effectiveness of lifestyle changes or medications. Normal blood pressure is essential for overall cardiovascular health.
Normal: Less than 120/80 mmHg - maintain healthy habits. Elevated: 120-129 systolic and less than 80 diastolic - risk of developing hypertension. Stage 1: 130-139 systolic or 80-89 diastolic - lifestyle changes recommended. Stage 2: 140+ systolic or 90+ diastolic - medical treatment likely needed. Crisis: Over 180/120 - seek immediate medical attention.
Rest for 5 minutes before measuring. Sit with your back supported and feet flat on the floor. Keep your arm at heart level. Use the correct cuff size. Avoid caffeine, exercise, and smoking for 30 minutes prior. Take multiple readings and average them. Measure at the same time daily for consistency.
A normal blood pressure reading is less than 120/80 mmHg, according to the American Heart Association. The top number (systolic) measures pressure when your heart beats, and the bottom number (diastolic) measures pressure when your heart rests between beats. Readings between 120-129 systolic and less than 80 diastolic are considered elevated.
If your blood pressure is normal (under 120/80), checking once a year at your annual physical is generally sufficient. If you have elevated or high blood pressure, your doctor may recommend checking it at home daily or several times a week. For best accuracy, measure at the same time each day, take two or three readings one minute apart, and record the results.
Yes, several lifestyle changes can help lower blood pressure naturally. These include reducing sodium intake to under 2,300 mg per day, exercising regularly (at least 150 minutes of moderate activity per week), maintaining a healthy weight, limiting alcohol consumption, managing stress, and eating a diet rich in fruits, vegetables, and whole grains (such as the DASH diet). However, always consult your doctor before making changes to any prescribed treatment plan.
