Blood Pressure Guide
Blood Pressure Guide
Understand normal blood pressure range, systolic and diastolic numbers, low BP, high BP, and when to consult a doctor.
1. What is Blood Pressure?
Blood pressure is the force of blood pushing against the walls of your arteries. It is measured using two numbers: systolic pressure and diastolic pressure.
- Systolic pressure: The top number, measured when the heart beats.
- Diastolic pressure: The bottom number, measured when the heart rests between beats.
2. Normal Blood Pressure Range
A normal adult blood pressure reading is usually considered around 120/80 mmHg. Blood pressure may vary depending on age, activity, stress, sleep, and health condition.
| Category | Systolic | Diastolic |
|---|---|---|
| Normal | Less than 120 | Less than 80 |
| Elevated | 120–129 | Less than 80 |
| High BP Stage 1 | 130–139 | 80–89 |
| High BP Stage 2 | 140 or higher | 90 or higher |
3. Blood Pressure Chart by Age
Blood pressure can change with age. The values below are general reference ranges and should not replace medical advice.
| Age Group | Typical BP Range |
|---|---|
| Children | Varies by age, height, and gender |
| Adults | Around 120/80 mmHg |
