Mastering Your Blood Pressure: Essential Knowledge for Everyone

What is Blood Pressure?

Blood pressure is the force exerted by your blood as it is pumped through your arteries. This pressure is closely linked to your heartbeats, as the heart is responsible for pumping blood into the arteries that distribute it throughout your body.

Blood carries vital components such as antibodies and white blood cells that protect your organs, as well as clotting platelets that prevent blood loss after an injury.

This process occurs 60 to 100 times per minute, 24 hours a day. Arteries deliver oxygen and nutrients to your entire body, while veins return blood to your heart.

Why Your Blood Pressure Changes

Many factors can influence blood pressure, including lifestyle, diet, and genetics. Other factors like ageing, medication, lack of exercise, and stress can also cause fluctuations. Both high and low blood pressure can be detrimental, and we'll delve into the specifics as we go on.

Why You Should Manage Your Blood Pressure

Blood pressure is highest as it leaves the heart and enters the arteries and gradually decreases as it moves through the arterial branches to other parts of the body.

The elasticity of artery walls helps maintain blood flow pressure from the heart and prevents it from dropping sharply. This ensures effective blood flow throughout the body. However, certain conditions can affect artery walls, causing them to narrow or become blocked, reducing blood flow and leading to health issues such as high blood pressure, stroke, cardiovascular disease, kidney disease, and more.

Measuring Your Blood Pressure

A sphygmomanometer, commonly known as a blood pressure cuff, is used to measure blood pressure. The cuff is wrapped around your upper arm and inflated to temporarily stop blood flow in your artery. Blood pressure readings have two numbers: the systolic pressure (the top number) and the diastolic pressure (the bottom number). For example, a reading might be 140/90 mm Hg.

The systolic pressure indicates the pressure during the heart's contraction, while the diastolic pressure measures the pressure in the arteries during the resting period between heartbeats.

Factors Affecting Your Blood Pressure

According to the National Institutes of Health and the American Heart Association (AHA), typical blood pressure is below 120/80 mm Hg. Since 2017, the AHA recommends treatment for blood pressure at or above 130/80 mm Hg. Low blood pressure, or hypotension, is indicated by readings below 90/60 mm Hg and can be as dangerous as hypertension (high blood pressure).

Doctors classify high blood pressure into four categories: elevated, hypertension stage 1, hypertension stage 2, and hypertensive crisis.

Risks of High Blood Pressure

Several factors increase the risk of high blood pressure, including:

• Family history of hypertension, cardiovascular disease, or diabetes

• Belonging to the Black community

• Being 60 years old or older

• High cholesterol levels

• Use of oral contraceptives

• Obesity

• Diabetes or high blood sugar levels

• Use of tobacco products

• Lack of exercise

• High-salt diet

Procedures for Accurate Blood Pressure Readings

To ensure accurate blood pressure measurements:

1. Avoid tobacco, food, drinks, exercise, and caffeine 30 minutes before measurement.

2. Use the bathroom to empty your bladder.

3. Rest for five minutes in a chair with your feet flat on the floor.

4. Sit up straight with your arm at heart level, relaxed on a table.

5. Use the correct cuff size, placing it on your bare upper arm.

For automatic readings, press the button to inflate the cuff. For manual readings, inflate the cuff with a pump and release air slowly while using a stethoscope to listen to your brachial artery. Repeat the measurement 2-3 times for accuracy.

Analyzing Your Blood Pressure Results

The systolic number indicates the pressure in your arteries during a heartbeat, while the diastolic number indicates the pressure when your heart rests between beats. Record these as two numbers separated by a slash, such as 120/80 mm Hg.

Blood pressure levels are categorized as follows:

• Normal: 120/80 mm Hg or lower

• Elevated: 120-129/80 mm Hg or lower

• Stage 1 High Blood Pressure: 130-139/80-89 mm Hg

• Stage 2 High Blood Pressure: 140/90 mm Hg or higher

• Hypertensive Crisis: Higher than 180/120 mm Hg

Blood pressure goals can vary based on age and health conditions, so work with your healthcare provider to determine your target range. If your readings are abnormal, seek medical advice for appropriate treatment.

Managing Your Blood Pressure

To manage your blood pressure, consider these measures:

• Maintain a healthy weight.

• Exercise for at least 150 minutes per week.

• Consume less than 1,500 mg of salt daily.

• Eat plenty of whole grains, fruits, and vegetables, and limit saturated fats.

• Avoid tobacco products.

• Limit alcohol intake to one or two drinks per day.

• Stay active.

• Reduce stress.

Recognizing Symptoms of Low Blood Pressure

Symptoms of low blood pressure include:

• Blurred vision

• Dizziness or lightheadedness

• Fainting

• Fatigue

• Trouble concentrating

• Upset stomach

A sudden drop in blood pressure can be dangerous, potentially leading to shock. Symptoms of shock include confusion, cold and clammy skin, pallor, rapid shallow breathing, and a weak rapid pulse.

Recognizing Symptoms of High Blood Pressure

If you get a high reading, recheck it. Consistently high readings require medical attention. Seek immediate help if you experience symptoms like:

• Shortness of breath

• Chest pain

• Back pain

• Vision changes

• Trouble speaking

• Numbness

• Headache

Regular check-ups with your doctor are crucial to managing blood pressure and preventing complications that could endanger your health.

Conclusion

Understanding and managing your blood pressure is vital for maintaining overall health and preventing serious conditions like heart disease, stroke, and kidney disease. By monitoring your blood pressure regularly, adopting a healthy lifestyle, and seeking medical advice when necessary, you can take control of your cardiovascular health.
