Type 2 diabetes is currently the fourth main cause of death in developing countries, with the number of people with this condition growing at a faster rate than ever before. With its more prominent and severe symptoms, it is far easier to detect type 1 diabetes, while type 2 diabetes can remain undetected for more than a decade (Diabetes UK 2008). It is therefore very difficult to estimate the number of people worldwide that currently have type 2. As an example, the number of cases in 1985 was estimated to be 30 million and by the year 2000, this estimate had risen to over 150 million; by 2011, the estimated number of type 2 diagnoses worldwide had risen to in excess of 312 million people—12 million more than the estimates up to the year 2025 had predicted (World Health Organisation 2011).
