According to the latest figures from the International Diabetes Federation (IDF), about 19 million people in Africa have diabetes. By 2045, this number will increase to about 47 million. The IDF reports that the prevalence of diabetes in South African adults is around 12.8%. T2DM accounts for over 90% of diabetes. What is worrying is that almost half of people with diabetes (49.7%) are undiagnosed. Diabetes often affect people of productive age, slows economic growth, reduces life-expectancy in the elderly, causes increasing healthcare expenditure.
