Blood Pressure Awareness Week: Know Your Numbers

4 Sep 2023 | Advice

Blood Pressure Awareness Week is an annual event highlighting cardiovascular health’s importance. High blood pressure affects millions worldwide, straining healthcare systems and causing preventable health issues. Awareness is crucial because it empowers people to recognise the signs of hypertension and take timely action. 

This year’s theme, “Know Your Numbers,” calls for individuals to be aware of their blood pressure levels, a critical step towards ensuring overall well-being. This blog post aims to highlight the importance of blood pressure awareness and provide valuable insights into this important aspect of health management.

Understanding Blood Pressure

High blood pressure, or hypertension, might be referred to as the “silent killer,” but its effects on health are far from quiet. Understanding how it can impact the body is essential in recognising its severity and the importance of managing it.

Cardiovascular Health

Elevated blood pressure puts excessive strain on the arteries and heart. Over time, this strain can lead to the development of various cardiovascular diseases, including coronary artery disease, heart attacks, and stroke. The forceful blood flow damages the inner lining of arteries, creating opportunities for plaque buildup, which can narrow the arteries and hinder blood flow.

Kidney Damage

The kidneys play a significant role in regulating blood pressure. High blood pressure can damage the blood vessels in the kidneys, impairing their ability to filter waste from the blood effectively. This can lead to kidney disease or even kidney failure.

Brain Health

The brain relies on a steady supply of oxygen-rich blood. High blood pressure can weaken blood vessels in the brain, increasing the risk of cognitive decline, vascular dementia, and strokes. Uncontrolled hypertension is a significant risk factor for both ischemic and hemorrhagic strokes.

Eye Complications

The tiny blood vessels in the eyes are also vulnerable to damage from high blood pressure. This can result in vision problems and, in severe cases, even blindness.

Peripheral Artery Disease

High blood pressure can cause arteries in the legs and other extremities to narrow and harden, reducing blood flow. This condition, known as peripheral artery disease, can lead to pain, infections, and tissue damage.

Health Conditions Frequently Related To High Blood Pressure

Coronary Artery Disease (CAD)

CAD occurs when the arteries that supply blood to the heart muscle become narrowed or blocked due to plaque buildup. Hypertension significantly increases the risk of developing CAD, as the heart has to work harder to pump blood against elevated pressure.

Heart Failure

Over time, the heart’s constant struggle against high blood pressure can lead to an enlarged heart and weakened muscles. This increases the likelihood of heart failure, a condition in which the heart can’t pump blood effectively to meet the body’s needs.


High blood pressure is a significant risk factor for stroke. When a blood vessel in the brain becomes blocked or bursts, it can result in brain damage or death. Managing blood pressure is crucial for reducing the risk of stroke.

Chronic Kidney Disease

Hypertension damages the blood vessels in the kidneys, reducing their ability to filter blood effectively. This can lead to chronic kidney disease, which may progress to kidney failure over time.

Vision Issues

Damage to the blood vessels in the eyes can cause various eye problems, including retinopathy and vision loss.

High Blood Pressure typically doesn’t cause noticeable symptoms in its early stages. However, as it progresses and remains uncontrolled, it can lead to serious health issues. Some people with high blood pressure may experience symptoms, but these symptoms are usually non-specific and can overlap with other conditions. 

Here are some potential signs and symptoms of high blood pressure:

Headaches: Some people with high blood pressure might experience headaches, especially in the morning. However, headaches are not a reliable indicator of high blood pressure, as various factors can cause them.

Nosebleeds: Occasional nosebleeds can occur in individuals with high blood pressure, but they are not definitive symptoms and can have other causes.

Shortness of Breath: Uncontrolled high blood pressure can lead to fluid buildup in the lungs, causing difficulty breathing and shortness of breath.

Dizziness or Lightheadedness: In some cases, high blood pressure can cause dizziness or lightheadedness. This can occur if blood pressure spikes suddenly.

Chest Pain: Chest pain is a potential symptom of high blood pressure-related heart problems, but it’s also associated with many other heart conditions.

The Know Your Numbers Campaign

Since high blood pressure often doesn’t present obvious symptoms, regular blood pressure checks are crucial, especially if you have risk factors such as a family history of hypertension, obesity, sedentary lifestyle, smoking, excessive alcohol consumption, or a diet high in sodium. 

Routine check-ups and screenings are essential for early detection and management of high blood pressure to prevent its potential complications. The “Know Your Numbers” campaign during Blood Pressure Awareness Week encourages individuals to monitor their blood pressure regularly through healthcare providers, free check-up events, or at-home blood pressure monitors.
