Why Many People Are Dying Young Without Knowing They Were Sick

Across Africa, an alarming number of young people are dying suddenly, often without prior knowledge of any underlying illness. These unexpected deaths raise serious concerns about undiagnosed diseases, poor access to healthcare, and a lack of awareness about preventive health measures.

The Silent Epidemic of Undiagnosed Diseases in Africa

Non-communicable diseases (NCDs) like heart disease, diabetes, high blood pressure, and chronic kidney disease are now leading causes of death in Africa. According to the World Health Organization (WHO), NCDs account for nearly 37% of all deaths in sub-Saharan Africa, many of which are in young adults who had no idea they were sick.

A 2022 report by the African Centre for Disease Control (Africa CDC) found that over 50% of hypertension and diabetes cases in Africa go undiagnosed. Many people only discover their condition when it is too late—often after suffering a heart attack, stroke, or organ failure.

Common Undiagnosed Conditions Leading to Sudden Death

1. Hypertension (High Blood Pressure)
   • Often called the “silent killer,” hypertension has no obvious symptoms until it leads to a stroke or heart attack.
   • A study in Nigeria revealed that 76.2% of people with high blood pressure were unaware of their condition.
2. Diabetes
   • More than 24 million Africans have diabetes, yet over 60% are undiagnosed, according to the International Diabetes Federation.
   • Many people only discover they have diabetes when complications like kidney failure, blindness, or limb amputation occur.
3. Heart Disease
   • Cardiovascular diseases now cause over 1 million deaths annually in Africa, and most victims had no idea they were at risk.
   • A Ghanaian study found that 1 in 5 sudden cardiac deaths occurred in young people under 40.
4. Kidney Disease
   • Chronic kidney disease (CKD) affects 15% of Africans, yet most cases go undetected until they reach end-stage renal failure.
   • The Kenya Renal Association reports that over 80% of CKD patients in Kenya are diagnosed too late to receive life-saving treatment.
5. Cancer
   • Cancer cases are rising in Africa, with many detected at terminal stages.
   • The WHO estimates that 70% of cancer cases in Africa are diagnosed too late, reducing survival chances.

Why Are These Diseases Going Undetected?

1. Lack of Regular Health Checkups
   • Many Africans only visit hospitals when they feel very sick, rather than for routine checkups.
   • Preventive screenings for blood pressure, blood sugar, and cholesterol are not a priority in many health systems.
2. Poor Access to Healthcare
   • WHO states that over 50% of Africans lack access to essential healthcare.
   • In rural areas, many people rely on herbal remedies instead of modern medical care.
3. Low Health Awareness
   • Many symptoms like fatigue, headaches, or weight loss are ignored until they worsen.
   • People mistake early disease signs for stress or minor infections.
4. Cost of Medical Tests
   • Many life-saving tests, like blood tests, ECGs, and CT scans, are too expensive for the average African.
   • A survey in Uganda found that over 70% of people skip medical tests due to cost.

How Can We Prevent These Silent Deaths?

1. Promote Regular Health Screenings
   • Governments and healthcare organizations must create free or subsidized screening programs.
   • Workplaces and schools should introduce mandatory annual health checks.
2. Increase Public Awareness
   • Media campaigns should educate people on early warning signs of diseases.
   • Community outreach programs should encourage people to seek medical help earlier.
3. Improve Healthcare Access
   • Governments should invest in affordable healthcare services to ensure early disease detection.
   • Mobile health clinics can help bring diagnostic services to remote areas.
4. Encourage a Healthy Lifestyle
   • Healthy eating, regular exercise, and stress management can prevent many lifestyle-related diseases.
   • Reducing alcohol intake, quitting smoking, and maintaining a balanced diet are crucial.

The sudden deaths of young people due to undiagnosed diseases highlight a critical failure in healthcare awareness and accessibility. By increasing routine medical checkups, public health education, and affordable healthcare services, Africa can prevent many of these tragic losses. No one should die without knowing they were sick—early detection can save countless lives.
