Diabetes is on the increase worldwide. The International Diabetes Federation estimates that there are currently 382 million persons diagnosed with diabetes. The prevalence is expected to increase to over 592 million in less than 25 years [1]. This increase is disproportional in the developing world, with 80% of those affected living in low- and middle-income countries. For example, in South and Central America, the prevalence of diabetes is estimated to increase by over 60% in the next two decades [2].
