South Africa has many serious health problems, and some can be deadly if not treated early. Diseases like tuberculosis, diabetes, heart disease, and HIV affect millions of people. Many of us ignore small health problems until they get worse, but knowing when to see a doctor can save your life.
Tuberculosis (TB)
TB is a dangerous lung disease that spreads when a sick person coughs or sneezes. It is very common in KwaZulu-Natal, Gauteng, and the Western Cape.
See a doctor if you have:
A cough lasting more than four weeks
Night sweats, fever, or weight loss
Coughing up blood
TB can be cured with medicine, but you must take it for six months. The sooner you get treatment, the better. Learn more about TB treatment: Department of Health South Africa
Diabetes
Diabetes happens when your body cannot control sugar properly. More than 4.5 million people in South Africa have this disease. Eating too much sugar and not exercising can make it worse.
See a doctor if you have:
Constant thirst and frequent urination
Unexplained weight loss or tiredness
Slow-healing wounds
Early treatment helps manage the condition and prevent complications. Diabetes awareness and support: Diabetes South Africa
Heart Disease and Stroke: The Silent Killers
Every day, more than 200 people in South Africa die from heart problems or strokes. Many people do not know they have high blood pressure until it is too late.
See a doctor if you have:
Chest pain or shortness of breath
Dizziness or difficulty speaking
Severe headache with blurry vision
You can lower your risk by eating healthy food, exercising, and managing stress. Doctors can also give medicine to help. Heart health tips: Heart & Stroke Foundation South Africa
HIV & AIDS: The Ongoing Fight
South Africa has the highest number of people living with HIV in the world—over 8.2 million. If not treated, HIV can weaken your body, making you very sick.
See a doctor if you have:
Constant fatigue and unexplained weight loss
Frequent infections and skin rashes
HIV can be managed with antiretroviral (ARV) treatment. Get tested early. Free HIV testing & treatment info: South African National AIDS Council (SANAC)
