Diabetes in South Africa: Prevention and Early Signs
The Diabetes Epidemic in South Africa
Diabetes is one of the fastest-growing chronic conditions in South Africa, with over 4.5 million people currently affected and many more undiagnosed. Type 2 diabetes accounts for roughly 90% of all cases and is largely preventable through lifestyle modifications and early detection.
Early Warning Signs
Understanding the early warning signs is crucial. Common symptoms include:
- Excessive thirst and frequent urination (especially at night)
- Unexplained fatigue
- Blurred vision
- Slow-healing wounds or frequent infections
- Tingling or numbness in the hands and feet
- Unexplained weight loss
Many people dismiss these symptoms as stress or ageing, which delays diagnosis and increases the risk of serious complications.
Risk Factors
You may be at higher risk if you have:
- A family history of diabetes
- Are overweight or obese (particularly abdominal weight)
- Lead a sedentary lifestyle
- Follow a diet high in refined carbohydrates and sugars
- Are over the age of 45
South Africa's high rates of obesity and urbanisation contribute significantly to the diabetes epidemic.
Screening and Early Detection
A simple fasting blood glucose test or HbA1c test can identify diabetes or pre-diabetes before symptoms become severe.
At NeoHealth, we recommend annual screening for:
- All adults over 40
- Anyone with risk factors (at any age)
Prevention
Prevention centres on sustainable lifestyle changes:
- Maintain a healthy weight
- Exercise at least 150 minutes per week
- Choose whole grains over refined carbohydrates
- Increase vegetable and fibre intake
- Limit sugary drinks
If you have been diagnosed with pre-diabetes, these changes can significantly reduce your risk of progressing to full diabetes. Book a screening at NeoHealth to know your numbers.
