As World Hypertension Day approaches on May 17, St. George’s University (SGU) School of Medicine is calling attention to the growing public health crisis of hypertension in Africa — a continent where urbanization and lifestyle changes are fueling a silent epidemic of high blood pressure.
Often dubbed the "silent killer," hypertension is the most prevalent cardiovascular condition worldwide and a major contributor to heart attacks, strokes, and kidney disease. According to the National Library of Medicine, it accounts for approximately 9.4 million deaths annually — nearly half of all cardiovascular fatalities. In Africa alone, the estimated prevalence of hypertension stands at 30.8%, with nearly half of adults aged 25 and over affected, as reported by the *Journal of Human Hypertension*.
SGU’s School of Medicine warns that the rapid shift in dietary habits and increasingly stressful urban environments are compounding the risks. Traditional meals are being replaced by processed foods, fast food, and red meat-heavy diets, while the average adult in Africa consumes up to 11.3 grams of salt daily — more than double the World Health Organization’s recommended limit of 5 grams.
“Hypertension isn’t just a result of poor diet — it’s also deeply linked to stress,” noted SGU. “With rising living costs, long work hours, digital overload, and daily traffic congestion, many Africans are living under chronic pressure that directly impacts cardiovascular health.”
One of the most alarming aspects of hypertension is its asymptomatic nature. Many individuals live with dangerously high blood pressure without any visible signs, only recognizing the issue when complications like headaches, vision problems, or strokes occur. SGU emphasizes that early detection through routine check-ups can be lifesaving — especially as more young adults in their mid-20s are being diagnosed due to obesity, smoking, and stress.
In response to the crisis, SGU recommends a three-pronged approach:
- Public Awareness:Campaigns must be more culturally tailored and far-reaching to educate populations on hypertension prevention.
- Early Detection: Encouraging routine blood pressure screenings, particularly through mobile clinics, digital tools, and workplace wellness initiatives, can help identify at-risk individuals early.
- Lifestyle Changes:Simple adjustments such as reducing salt and red meat intake, increasing physical activity, staying hydrated, and managing stress through mindfulness can have a profound impact.
