When is diabetes really diabetes?

In Australia, 7.5% of the adult population has diabetes, and for every one person diagnosed with diabetes there is another undiagnosed.1 The prevalence of the most common form of diabetes, type 2, is increasing worldwide because of changing lifestyle, especially increasing weight caused by nutritional excess and decreasing physical activity. Many people with type 2 diabetes have cardiovascular and renal complications on diagnosis, and early detection of diabetes is an important strategy for reducing morbidity and premature mortality.2
