Understanding Blood Pressure
What is Blood Pressure?
Blood pressure is the force of blood pushing against the walls of your arteries as your heart pumps blood.
Two Numbers
Systolic (top number) measures pressure when heart beats. Diastolic (bottom number) measures pressure between beats.
Why It Matters
High blood pressure increases risk of heart disease, stroke, and kidney problems without showing symptoms.
Blood Pressure FAQs
What is a normal blood pressure reading?
A normal blood pressure reading is typically less than 120/80 mm Hg. The systolic (top number) should be under 120 and diastolic (bottom number) under 80.
How often should I check my blood pressure?
If you have normal blood pressure, check it at least once a year. If you have high blood pressure or risk factors, your doctor may recommend more frequent monitoring.
What factors affect blood pressure?
Diet (especially salt intake), physical activity, stress, alcohol consumption, smoking, age, genetics, and certain medications can all affect blood pressure.
When should I see a doctor about my blood pressure?
Consult a doctor if your readings are consistently 130/80 or higher, or if you experience symptoms like severe headaches, chest pain, or vision problems.
Can I lower my blood pressure naturally?
Yes, through lifestyle changes like reducing sodium intake, exercising regularly, maintaining a healthy weight, limiting alcohol, and managing stress.
