Understanding Blood Pressure
What Do the Numbers Mean?
Blood pressure is measured in millimeters of mercury (mmHg) and recorded as two numbers:
- Systolic Pressure (top number): Pressure when your heart beats and pumps blood
- Diastolic Pressure (bottom number): Pressure when your heart rests between beats
Blood Pressure Categories (AHA Guidelines)
Normal: Less than 120/80 mmHg
Maintain heart-healthy habits like following a balanced diet and getting regular exercise.
Elevated: 120-129 systolic and less than 80 diastolic
Take action to control this condition through lifestyle changes to prevent progression to high blood pressure.
Stage 1 Hypertension: 130-139 systolic or 80-89 diastolic
Doctors may prescribe lifestyle changes and may consider adding blood pressure medication.
Stage 2 Hypertension: 140/90 mmHg or higher
Doctors will likely prescribe a combination of blood pressure medications and lifestyle changes.
Hypertensive Crisis: Higher than 180 systolic and/or higher than 120 diastolic
This requires immediate medical attention. If symptoms are present, call emergency services.
Risk Factors for High Blood Pressure
Modifiable Risk Factors
- Diet: High sodium, low potassium intake
- Physical Inactivity: Sedentary lifestyle
- Obesity: BMI ≥30 kg/m²
- Smoking: Tobacco use and secondhand smoke
- Alcohol: Excessive alcohol consumption
- Stress: Chronic psychological stress
- Sleep: Poor sleep quality or sleep apnea
Non-Modifiable Risk Factors

- Family History: Genetic predisposition
- Race: Higher prevalence in certain ethnic groups
Complications of High Blood Pressure
- Heart Disease: Coronary artery disease, heart failure
- Stroke: Brain damage due to blocked or burst blood vessels
- Kidney Disease: Chronic kidney disease and kidney failure
- Eye Problems: Retinopathy and vision loss
- Peripheral Artery Disease: Reduced blood flow to limbs
- Aneurysms: Dangerous bulging of blood vessels
The DASH Diet for Blood Pressure
Dietary Approaches to Stop Hypertension (DASH) diet has been proven to lower blood pressure:
- Fruits and Vegetables: 8-10 servings per day
- Whole Grains: 6-8 servings per day
- Lean Protein: Fish, poultry, beans, nuts
- Low-fat Dairy: 2-3 servings per day
- Limited Sodium: Less than 2,300mg per day (ideally 1,500mg)
- Limited Saturated Fat: Less than 7% of calories
Home Blood Pressure Monitoring
- Best Times: Morning and evening, same times daily
- Preparation: Sit quietly for 5 minutes before measuring
- Position: Feet flat on floor, arm at heart level
- Cuff Size: Proper cuff size is crucial for accuracy
- Multiple Readings: Take 2-3 readings 1 minute apart
- Record Keeping: Log readings with date and time
