Diabetes is a chronic health condition that affects how the body processes blood sugar (glucose). It is one of the most common non-communicable diseases worldwide and is a growing concern in South Africa.
If not properly managed, diabetes can lead to serious complications affecting the heart, kidneys, eyes, and nerves. However, with early detection and proper care, individuals with diabetes can live healthy and active lives.
Understanding diabetes is essential for prevention, early diagnosis, and effective management.
