Understanding Diabetes: Types and Global Context
Diabetes is one of the most prevalent chronic conditions worldwide, and more than a half a billion people received diabetes diagnosis. Read more epidemiological information below.
Diabetes Facts and Figures
According to the International Diabetes Federation (IDF), 1 in 9 people are living with diabetes worldwide. 589 mln adults (20-79) are living with diabetes.
Another 252 million individuals (≈43%) are undiagnosed, with nearly 90% of these cases in low- and middle-income countries IDF’s Diabetes Atlas.
These numbers are projected to rise to 643 million by 2030 and 784 million by 2045. Roughly 1.8 million children and young adults under 20 live with type 1 diabetes, and many more people over 20 are living with type 1 diabetes, however, the accurate numbers are lacking.
Types of Diabetes
Type 1 diabetes is an autoimmune condition where the pancreas produces little to no insulin. It is typically diagnosed in children and young adults, but can be diagnosed at any stage of life (over 50 as well). See more information about type 1 diabetes here: Type 1 diabetes.
Type 2 diabetes is a metabolic condition characterised by insulin resistance and eventual pancreatic beta-cell dysfunction. It is more common in adults and is often, but not always, associated with lifestyle factors. See more information about type 2 diabetes here: Type 2 diabetes.
Other types of diabetes – e.g. MODY or gestational diabetes contribute to the overall numbers, but the accurate data evidence is lacking. Read here about other types of diabetes.
Global diabetes-related healthcare costs exceeded US $1 trillion in 2024—a 338% increase over 17 years.
Summary:
- Diabetes is a global pandemic
- Undiagnosed cases remain a massive blind spot, especially in developing countries.
- The economic cost of diabetes is very high, with healthcare costs now exceeding $1 trillion annually. Mostly, the cost of diabetes complications contributes to these costs
- Age, urbanization, socio-economic status and region continue shaping the diabetes burden; older adults and urban residents are disproportionately affected.
- Expected increasing prevalence is a continuous challenge for healthcare systems worldwide.
