Cape Town: City observed World Hypertension Day, which is commemorated on May 17 every year. The theme for this year was ‘Controlling Hypertension Together: check your blood pressure regularly, defeat the silent killer’. Hypertension, or high blood pressure, does not necessarily present with symptoms, which is why it is called the silent killer.
Reportedly, City Health data shows that the public is responding to calls to be screened for the disease known as ‘the silent killer’. While the number of cases too is on the rise, it means that treatment can begin to mitigate the impacts.
During the 2024-25 financial year, City clinics conducted 683,638 blood pressure screenings, while 4,486 residents were newly diagnosed with hypertension. Screenings increased significantly compared to the previous year, and so too did diagnoses. It highlighted both growing awareness and the continued risk posed by the condition.
Of concern is that over 2200 residents aged 18 to 44 were newly diagnosed during the year. They reinforced that hypertension is not only a condition affecting older persons. Left undiagnosed and uncontrolled, it can lead to serious complications including stroke, heart disease, kidney failure and vision loss.
Considering this, Member of the Mayoral Committee for Community Services and Health – Councillor Francine Higham stated that high blood pressure often develops without symptoms, which is why regular screening matters, even if you feel healthy. While hypertension is more common in older persons, they are also seeing younger residents affected by it, which is a reminder that no one should assume they are too young to get checked.
The good news is that screening is quick, free and available at all City clinics, including through the City’s youth-friendly services, which are designed to make health care accessible and welcoming for young adults. A few minutes spent to check your blood pressure today could prevent serious health complications in the future.
Notably, all City clinics offer routine blood pressure screening during visits. While residents can also make use of the City of Cape Town’s Healthcare Appointments System to book clinic visits in advance and improve convenience.
Residents are also encouraged to adopt practical, everyday habits to reduce their risk of developing hypertension and other non-communicable diseases (NCDs). This includes limiting salt intake, particularly from processed and fast foods such as chips, processed meats, instant meals and takeaway options.
Being physically active for at least 30 minutes most days of the week and choosing more fresh foods like fruit and vegetables where possible. Reducing or avoiding tobacco use and limiting alcohol consumption are also key steps in protecting long-term health.
For those diagnosed with hypertension, adherence to prescribed treatment and regular follow-up visits are essential. Early detection saves lives and knowing your numbers could make all the difference. Residents can visit their nearest public healthcare facility for free blood pressure screening and health advice.
