This World Diabetes Day, we’re shining a light on one of the most important health challenges of our time, diabetes, and what we can all do to prevent it.
Diabetes occurs when the body either doesn’t produce enough insulin, or can’t use it effectively, leading to elevated blood sugar levels. Over time, this can damage the heart, blood vessels, kidneys, eyes and nerves.
🔹Type 1 Diabetes: an autoimmune condition where the body stops producing insulin.
🔹Type 2 Diabetes: far more common, and often linked to lifestyle, metabolic health and genetics.
Global & South African Stats:
🌐 Globally: 589 million adults (20–79 yrs) are living with diabetes - that is about 1 in 10 adults worldwide.
🇿🇦 South Africa: Around 2.3 million adults are estimated to have diabetes (7.2 % prevalence), though other studies suggest up to 4.2 million adults, roughly 1 in 9, may be affected.
Alarmingly, many South Africans remain undiagnosed or undertreated, making early detection and education vital.

Before Type 2 Diabetes develops, many people experience insulin resistance, when the body’s cells stop responding properly to insulin. The pancreas works overtime to produce more insulin, but eventually can’t keep up and blood glucose begins to rise.
This often coincides with metabolic syndrome - a cluster of risk factors that include:
➡️ Abdominal fat (especially around the waist)
➡️ High blood pressure
➡️ Elevated fasting glucose
➡️ Low HDL (“good”) cholesterol
➡️ High triglycerides
Together, these signal metabolic imbalance and a higher risk of Type 2 Diabetes and heart disease. The good news? With the right lifestyle changes, healthy nutrition, regular movement, good sleep and stress management, insulin sensitivity can often be restored, and long-term risk reduced dramatically.
What You Can Do:
1. Know your risk: Family history, age (45+), excess weight, inactivity, high blood pressure or cholesterol all increase your risk.
2. Get screened: If you have risk factors or symptoms (thirst, frequent urination, fatigue, blurred vision), talk to your healthcare provider.
3. Prioritise a healthy lifestyle:
✅ Eat whole, unprocessed foods
✅ Move your body regularly
✅ Manage stress
✅ Avoid smoking and limit alcohol
4. If diagnosed: Monitor blood sugar, work closely with your healthcare team, attend regular check-ups and follow your treatment plan.
5. Support mental wellbeing: Living with a chronic condition can be challenging; reach out, talk openly and find support.
At Innersight, our mission is to help you live not just longer, but better. Diabetes and metabolic dysfunction accelerate ageing and disease risk, but early action, awareness and lifestyle choices can truly change your future health trajectory.
Let’s use World Diabetes Day as a moment to check in with our health, our habits and each other.
