1. What is Blood Pressure?

Definition: Blood pressure is the force of circulating blood on the walls of the arteries, measured in millimeters of mercury (mmHg).

Components:

• Systolic BP (SBP): The pressure when the heart beats (higher number)
• Diastolic BP (DBP): The pressure when the heart rests between beats (lower number)

2. Blood Pressure Categories

The American Heart Association defines these categories:

Category	SBP (mmHg)	DBP (mmHg)
Low BP	<90	<60
Normal	<120	<80
Elevated	120-129	<80
Stage 1 Hypertension	130-139	80-89
Stage 2 Hypertension	≥140	≥90
Hypertensive Crisis	≥180	≥120

3. Importance of Blood Pressure Monitoring

Details: Regular monitoring helps detect hypertension early, reducing risks of heart disease, stroke, and kidney problems.

4. Using the Calculator

Tips: Enter your systolic and diastolic blood pressure numbers to determine your category. For accurate results, measure after resting for 5 minutes.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal blood pressure?
A: Normal blood pressure is below 120/80 mmHg.

Q2: When should I see a doctor about my blood pressure?
A: Consult a doctor if your reading is consistently 130/80 or higher, or if you experience symptoms like headaches or dizziness.

Q3: How often should I check my blood pressure?
A: Adults should check at least once a year, more frequently if you have risk factors for hypertension.

Q4: Can stress affect my blood pressure?
A: Yes, stress can temporarily increase blood pressure. Take multiple readings at different times for accuracy.

Q5: What should I do if my blood pressure is high?
A: Lifestyle changes like reducing salt, exercising, and weight management can help. Consult a doctor for persistent high readings.
