Diabetes is the singlemost important metabolic disease which can affect nearly every organ system in the body. It has been projected that 300 million individuals would be affected with diabetes by the year 2025. In India it is estimated that presently 19.4 million individuals are affected by this deadly disease, which is likely to go up to 57.2 million by the year 2025. The reasons for this escalation are due to changes in lifestyle, people living longer than before (ageing) and low birth weight could lead to diabetes during adulthood. Diabetes related complications are coronary artery disease, peripheral vascular disease, neuropathy, retinopathy, nephropathy, etc. People with diabetes are 25 times more likely to develop blindness, 17 times more likely to develop kidney disease, 30-40 times more likely to undergo amputation, two to four times more likely to develop myocardial infarction and twice as likely to suffer a stroke than non-diabetics. Lifestyle modifications, inclusive of dietary modification, regular physical activity and weight reduction are indicated for prevention of diabetes.
