About Blood Pressure
Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.
Understanding Your Results
The blood pressure categories defined by the American Heart Association are:
- Low Blood Pressure: Below 90/60 mmHg - May cause dizziness or fainting
- Normal: Below 120/80 mmHg - Ideal for cardiovascular health
- Elevated: 120-129/<80 mmHg - Increased risk of developing hypertension
- Hypertension Stage 1: 130-139/80-89 mmHg - Lifestyle changes recommended
- Hypertension Stage 2: 140+/90+ mmHg - Medical treatment usually needed
- Hypertensive Crisis: 180+/120+ mmHg - Seek immediate medical attention
Risk Factors
Several factors can increase your risk of high blood pressure, including age, family history, being overweight, lack of physical activity, tobacco use, too much salt in your diet, too little potassium, drinking too much alcohol, stress, and certain chronic conditions like kidney disease and diabetes.
Management and Prevention
Lifestyle changes can help prevent and manage high blood pressure. These include eating a healthy diet (low in salt, high in fruits and vegetables), maintaining a healthy weight, being physically active, limiting alcohol, not smoking, managing stress, and monitoring your blood pressure at home.
When to See a Doctor
If your blood pressure is consistently above normal, or if you experience symptoms like severe headaches, chest pain, difficulty breathing, nausea, vomiting, blurred vision, or confusion (signs of a hypertensive crisis), seek medical attention immediately.
