[Comment] Staging prediabetes and type 2 diabetes: the time to start is now

Impaired glucose tolerance and impaired fasting glucose have long been recognised as risk factors for type 2 diabetes development. The term prediabetes was introduced by the American Diabetes Association (ADA)1 in 2011, with the intention to recognise intermediate glucose values between normal and diabetes as a risk factor for development of type 2 diabetes and to encourage clinicians to recommend lifestyle modifications to delay progression to type 2 diabetes. Over the past decade, strong associations have been shown between prediabetes and risk for cardiovascular diseases, chronic kidney disease, early-onset dementia, and some cancers, such as colorectal, breast, and pancreatic cancer,2,3 suggesting that prediabetes is a disease with broader implications on health.
