Understanding Blood Pressure

Blood pressure measures the force of blood pushing against your artery walls. It's recorded as two numbers:

• Systolic (top number): Pressure when your heart beats
• Diastolic (bottom number): Pressure between beats

Blood Pressure Categories

Category	Systolic	Diastolic	Action
Normal	Less than 120	Less than 80	Maintain healthy lifestyle
Elevated	120-129	Less than 80	Lifestyle changes
High (Stage 1)	130-139	80-89	Consult doctor, lifestyle changes
High (Stage 2)	140 or higher	90 or higher	Medical treatment recommended
Crisis	Higher than 180	Higher than 120	Seek immediate medical care

Risks of High Blood Pressure

Cardiovascular Risks

• Heart disease and heart attack
• Stroke
• Heart failure
• Irregular heartbeat (arrhythmia)

Organ Damage

• Kidney damage
• Vision loss
• Memory problems
• Peripheral artery disease

How to Lower Blood Pressure

Lifestyle Changes

1. Reduce sodium: Aim for under 2,300mg daily
2. Exercise regularly: 150 minutes per week
3. Maintain healthy weight: Even 10 lbs can help
4. Limit alcohol: No more than 1-2 drinks daily
5. Don't smoke: Tobacco raises BP temporarily and permanently
6. Manage stress: Practice relaxation techniques

Dietary Approaches

The DASH (Dietary Approaches to Stop Hypertension) diet emphasizes:

• Fruits, vegetables, whole grains
• Lean proteins and low-fat dairy
• Limited saturated fat and added sugars

Frequently Asked Questions

What do the two blood pressure numbers mean?

The top number (systolic) is pressure when your heart pumps blood. The bottom number (diastolic) is pressure when your heart rests between beats. Both matter for heart health.

When should I be concerned about my blood pressure?

Contact your doctor if readings are consistently 130/80 or higher. Seek immediate care for readings above 180/120 - this is a hypertensive crisis requiring emergency attention.

Can I check my blood pressure at home?

Yes! Home BP monitors are widely available. Take readings at the same time daily, sit quietly for 5 minutes before measuring, and use proper cuff size for accurate results.

Is isolated systolic hypertension dangerous?

Yes, it's the most common form of high blood pressure in older adults and increases risk of heart attack, stroke, and kidney disease. It requires treatment.
