The number of people with prediabetes is increasing worldwide. In 2010, the prevalence of prediabetes was estimated to be 344 million adults. This figure is expected to rise to 472 million by 2030.1 In 2009, there were over seven million UK adults with prediabetes, and the number of people diagnosed continues to increase.
Prediabetes, also known as impaired glucose regulation, is a precursor condition for type 2 diabetes. Although in many cases it is reversible, prediabetes frequently remains undiagnosed and therefore increases the risk of developing type 2 diabetes. In fact, people with prediabetes are up to 15 times more likely to develop type 2 diabetes.2
By 2025, it is estimated that five million people will have diabetes in the UK, which, apart from personal costs, places a huge financial burden on the NHS. Currently, people with diabetes require at least two to three times the healthcare resources of people who do not have diabetes, and diabetes care accounts for up to 10 per cent of hospital budgets.3, 4
Furthermore, as an increasing number of people in younger age groups are affected, with type 2 diabetes being diagnosed in children and adolescents, most experts agree that diabetes is one of the biggest health challenges currently facing the UK.5
