Understanding Your Blood Pressure

Blood pressure is the force of your blood pushing against the walls of your arteries. Arteries are the blood vessels that carry blood from your heart to other parts of your body. High blood pressure, also known as hypertension, can lead to serious health problems like heart attack, stroke, and kidney disease if left untreated.

What Do the Numbers Mean?

Blood pressure readings are given as two numbers:

• Systolic Pressure (the top number): This measures the pressure in your arteries when your heart beats.
• Diastolic Pressure (the bottom number): This measures the pressure in your arteries when your heart rests between beats.

Both numbers are important. The unit of measurement for blood pressure is millimeters of mercury (mmHg).

Blood Pressure Categories (AHA/ACC Guidelines):

• Normal: Systolic less than 120 mmHg AND Diastolic less than 80 mmHg.
• Elevated: Systolic 120-129 mmHg AND Diastolic less than 80 mmHg.
• High Blood Pressure (Hypertension) Stage 1: Systolic 130-139 mmHg OR Diastolic 80-89 mmHg.
• High Blood Pressure (Hypertension) Stage 2: Systolic 140 mmHg or higher OR Diastolic 90 mmHg or higher.
• Hypertensive Crisis: Systolic higher than 180 mmHg AND/OR Diastolic higher than 120 mmHg. This requires immediate medical attention.

Why Monitor Your Blood Pressure?

Regularly checking your blood pressure is crucial because hypertension often has no symptoms. Many people don't know they have it until it causes serious health issues. Monitoring helps you and your doctor detect problems early and take steps to manage your blood pressure through lifestyle changes or medication.

Factors Affecting Blood Pressure:

Several factors can influence your blood pressure, including:

• Age
• Genetics
• Diet (especially sodium intake)
• Physical activity level
• Weight
• Stress
• Smoking and alcohol consumption
• Certain medical conditions and medications
