Frequently Asked Questions
- What do the systolic and diastolic numbers mean?
The systolic number (the upper number) represents the pressure in your arteries when your heart beats. The diastolic number (the lower number) represents the pressure in your arteries when your heart rests between beats. Blood pressure is measured in millimeters of mercury (mmHg) and written as systolic over diastolic (e.g., 120/80 mmHg).
- How often should I check my blood pressure?
If your blood pressure is normal (less than 120/80 mmHg), get it checked at least once every 1-2 years. If you have elevated blood pressure or other risk factors, your doctor may recommend more frequent measurements. For those with hypertension, home monitoring is often recommended, with frequency determined by your healthcare provider.
- What causes high blood pressure?
High blood pressure can be caused by various factors including: genetics and family history, age (risk increases as you get older), unhealthy diet (especially high sodium), physical inactivity, obesity, excessive alcohol consumption, tobacco use, stress, certain chronic conditions (kidney disease, diabetes), and some medications. In most cases, the exact cause is unknown, which is called essential hypertension.
- Can I lower my blood pressure without medication?
Yes, many people can lower their blood pressure through lifestyle changes, especially those with elevated or Stage 1 hypertension. Effective strategies include: following the DASH diet (rich in fruits, vegetables, whole grains, and low-fat dairy), reducing sodium intake, regular physical activity, maintaining a healthy weight, limiting alcohol, quitting smoking, and managing stress. However, some people may still need medication despite these efforts.
- What is a hypertensive crisis and what should I do?
A hypertensive crisis is a severe increase in blood pressure (above 180/120 mmHg) that can lead to organ damage. It's a medical emergency. If you have these readings along with symptoms like severe headache, shortness of breath, nosebleeds, or severe anxiety, call emergency services (911) or go to the nearest emergency room immediately. Do not try to lower your blood pressure on your own in this situation.
