Blood Pressure FAQs
Common questions about blood pressure and cardiovascular health
What is considered normal blood pressure?▼
Normal blood pressure is less than 120/80 mmHg. The first number (systolic) measures pressure when your heart beats, and the second number (diastolic) measures pressure when your heart rests between beats.
How often should I check my blood pressure?▼
Adults should have their blood pressure checked at least once every two years if it's normal. If you have high blood pressure or other risk factors, your doctor may recommend more frequent monitoring.
What causes high blood pressure?▼
High blood pressure can be caused by various factors including genetics, age, diet (especially high sodium), lack of exercise, obesity, smoking, excessive alcohol consumption, stress, and certain medical conditions.
Can lifestyle changes lower blood pressure?▼
Yes! Lifestyle changes can significantly lower blood pressure. These include maintaining a healthy weight, eating a balanced diet low in sodium, exercising regularly, limiting alcohol, not smoking, and managing stress.
When should I see a doctor about my blood pressure?▼
See a doctor if your blood pressure is consistently 130/80 mmHg or higher, if you have symptoms like severe headaches, chest pain, or shortness of breath, or if you have risk factors for cardiovascular disease.
What is white coat hypertension?▼
White coat hypertension occurs when blood pressure readings are higher in a medical setting than at home, often due to anxiety or stress. Home monitoring can help identify this condition and provide more accurate readings.
