AbstractDiabetes mellitus has reached epidemic proportions worldwide as we enter the new millennium. The World Health Organization (WHO) has commented there is 'an apparent epidemic of diabetes which is strongly related to lifestyle and economic change'. Over the next decade the projected number will exceed 200 million, possibly reaching 250 million persons. Most will have type 2 diabetes and all are at risk of the development of complications. Better education, improved nutrition, more exercise, early diagnosis and prompt treatment are imperative. Diabetes is a serious disease, subject to the development of many complications affecting large vessels (heart, cerebral and peripheral), small vessels (kidney and retina), nerves and other organs. In type 2 diabetes these complications may precede diagnosis of the disease by many years. The process continues inexorably, with premature mortality and morbidity mainly from the development of vascular disease. Data from the WHO confirm the principal role of non-communicable disease on mortality in developed countries, while mortality in developing countries is rising rapidly, now often exceeding communicable disease. The non-communicable diseases are divided into cancer and degenerative diseases. In the developed world, degenerative diseases are grouped to include ischaemic heart disease, stroke, renal failure, hypertension and other macro- and microvascular diseases. The major complications of diabetes encountered most frequently and with the greatest impact are: 1. Neuropathy, both peripheral and autonomic, with principal manifestations in the lower limbs 2. Microvascular disease, mainly affecting the retina and kidney, resulting in blindness and renal failure 3. Macrovascular disease, presenting with atherosclerosis in the coronary arteries causing ischaemic heart disease, cerebrovascular disease causing stroke and peripheral vascular disease contributing to diabetic gangrene.
