Diabetes mellitus is the most common chronic disease in the industrialized world. In North America and Europe the prevalence in adults is 7–8% and it is estimated that there are more than 100 million cases worldwide. With the increasing prevalence of non-insulin-dependent diabetes mellitus (NIDDM) this figure continues to rise. The World Health Organization predicts that the number of patients with diabetes will rise from 130 million to over 300 million over the next 25 years. Diabetes affects 1 in 30 people living in England and Wales and accounts for more than £2 billion of hospital costs annually. The number of diabetic patients in the UK is predicted to double to 3 million by the year 2010.
