World Hypertension Day: Why Knowing Your Numbers Could Save Your Life

Every year on 17 May, the world comes together to recognise World Hypertension Day, a global awareness initiative focused on one of the most pressing public health challenges: high blood pressure. This year’s theme, Measure Your Blood Pressure Accurately, Control It, Live Longer, places emphasis on early detection, accurate diagnosis, and better management of hypertension, which continues to affect millions of people worldwide. Despite its prevalence, many remain unaware that they have high blood pressure until it has already caused serious damage. According to the World Health Organisation (2024), the condition is often silent, but its consequences can be life-altering, including stroke, heart attack, kidney failure, and even death. 

Understanding Hypertension 

Hypertension, commonly referred to as high blood pressure, occurs when the force of the blood against the walls of the arteries remains consistently elevated. Over time, this increased pressure can damage the arteries and strain the heart, leading to a range of health complications. It is known as the “silent killer” precisely because it usually presents no obvious symptoms in its early stages. Many people may live with hypertension for years without ever knowing it, all the while their health quietly deteriorates. 

Normal blood pressure is generally considered to be around 120/80 mmHg. When readings exceed 140/90 mmHg on a consistent basis, it is classified as hypertension and requires medical attention. As Heart Foundation South Africa explains, nearly one in every three adults in South Africa is affected by high blood pressure, and the risks associated with the condition are not limited to age or gender. Anyone, regardless of background or lifestyle, can be affected. 

Why Hypertension Matters 

The danger of hypertension lies in its cumulative effects on the body. Persistently high blood pressure can harden arteries, reduce blood flow, and ultimately lead to severe complications such as cardiovascular disease, kidney failure, vision loss, and even cognitive impairment. These outcomes not only impact individual health and quality of life but also place a significant burden on families, communities, and the healthcare system as a whole. 

For many people, the diagnosis of hypertension comes after a serious event like a stroke or heart attack, outcomes that could potentially have been prevented with regular monitoring and earlier intervention. This is why initiatives such as World Hypertension Day are so vital: they shine a light on the importance of prevention, detection, and proper treatment. 

What Increases the Risk? 

Several lifestyle and genetic factors contribute to the development of hypertension. While genetics can play a role, the condition is often influenced by poor dietary habits, especially a high intake of salt, processed foods, and saturated fats. A lack of physical activity, excessive alcohol consumption, and smoking further elevate risk levels. Chronic stress, untreated mental health conditions, and being overweight also contribute to the problem. As people age, arteries naturally become stiffer, which can also contribute to higher blood pressure. 

Many of us are vulnerable to these risk factors. Urban living, demanding work schedules, and sedentary lifestyles have made it easier to fall into habits that compromise our long-term health. That’s why awareness, regular check-ups, and timely interventions are so important. 

Prevention and Management 

The good news is that hypertension is both preventable and manageable. The key to prevention is a heart-healthy lifestyle. This includes consuming a balanced diet rich in fruits, vegetables, whole grains, and lean proteins while limiting sodium, sugar, and processed foods. Regular physical activity, even just a brisk 30-minute walk five days a week, can significantly lower blood pressure and improve overall cardiovascular health. 

Stress management is equally important. Chronic stress can elevate blood pressure and lead to unhealthy coping behaviours such as overeating or smoking. Finding healthy outlets for stress, such as exercise, hobbies, or mindfulness practices, can make a meaningful difference. For those already diagnosed with hypertension, prescribed medications and consistent follow-up with healthcare professionals are essential to prevent complications. 

Routine screenings are vital to prevention, particularly for individuals with a family history of hypertension or other risk factors. Early detection can allow for prompt treatment before complications arise. World Hypertension Day is a valuable reminder to schedule that check-up and to “know your numbers” before symptoms appear. 

Planning for the Unexpected 

While managing your physical health is key, it’s also essential to plan for the unexpected. A medical emergency related to hypertension, whether it’s a hospital admission, specialist treatment, or surgery, can place considerable strain on your finances. Without adequate medical cover, the cost of care can be significant, and out-of-pocket expenses can catch families off guard. 

At Securitas Financial Group®, we believe that good health and sound financial planning go hand in hand. While medical aid covers many core services, treatment for hypertension may involve consultations, diagnostic tests, chronic medication, and emergency care — some of which may not be fully covered by your plan. This is where having medical aid and gap cover becomes critical. Gap cover bridges the difference between what your medical scheme pays and what healthcare providers charge, ensuring you don’t have to compromise on care when it matters most. 

If you’re uncertain whether your current medical cover is sufficient, it may be helpful to speak with a qualified financial advisor. With a better understanding of your healthcare needs and financial goals, our advisors can help you find a solution that provides peace of mind. You can find an advisor here to assist you with a personalised review. 

Final Thoughts 

On this World Hypertension Day, we are reminded that our health is our most valuable asset. High blood pressure might not always feel urgent, but ignoring it can lead to irreversible damage. Prevention starts with education, and lasting change begins with action. Whether it’s making small changes to your daily routine or reviewing your healthcare plan, taking proactive steps today can protect your future. 

It’s never too early, or too late, to prioritise your health. So take a moment, check your blood pressure, and start the conversation with your healthcare provider. Your heart and your future self will thank you for it.
