Understanding Your Blood Pressure
Blood pressure is one of the most important vital signs. It measures the force of blood against your artery walls and is recorded as two numbers: systolic (pressure when the heart beats) over diastolic (pressure when the heart rests).
What each category means
- Normal (<120/80): Your heart and blood vessels are working efficiently. Continue healthy habits like regular exercise and a balanced diet.
- Elevated (120-129/<80): You are at risk of developing high blood pressure. Focus on reducing sodium, increasing physical activity, and managing stress.
- Stage 1 Hypertension (130-139/80-89): Your doctor may recommend lifestyle changes and consider medication depending on your cardiovascular risk.
- Stage 2 Hypertension (≥140/≥90): Most doctors will prescribe a combination of medications and lifestyle changes at this stage.
- Hypertensive Crisis (>180/>120): This requires immediate medical attention. If accompanied by symptoms such as chest pain, shortness of breath, or vision changes, call emergency services.
Lifestyle tips
- Aim for at least 150 minutes of moderate-intensity exercise per week.
- Limit sodium intake to less than 2,300 mg per day (ideally 1,500 mg).
- Eat potassium-rich foods like bananas, spinach, and sweet potatoes.
- Maintain a healthy weight — even a 5 kg loss can lower BP significantly.
- Limit alcohol to no more than one drink per day for women, two for men.
- Manage stress through meditation, deep breathing, or regular relaxation.
Frequently Asked Questions
What is blood pressure?+
Blood pressure is the force of blood pushing against the walls of your arteries as your heart pumps. It is measured in millimeters of mercury (mmHg) with two numbers: systolic (when the heart beats) over diastolic (when the heart rests between beats).
How often should I check my blood pressure?+
The AHA recommends adults with normal BP check at least once a year. If you have elevated or high readings, your doctor may suggest checking more frequently — sometimes daily at home with a validated monitor.
What is a normal blood pressure for my age?+
For most adults, a normal blood pressure is below 120/80 mmHg regardless of age. However, blood pressure tends to rise with age due to arterial stiffness. Children and teens have different normal ranges. Consult your doctor for age-specific guidance.
Can lifestyle changes help lower blood pressure?+
Yes. Regular exercise, reducing sodium intake, maintaining a healthy weight, limiting alcohol, managing stress, and eating a diet rich in fruits, vegetables, and whole grains (like the DASH diet) can all significantly lower blood pressure.
