Diabetes is one of the most common non-communicable diseases worldwide. It is no longer a disease of the ageing population in developed countries. Diabetes or pre-diabetes is increasingly being diagnosed in the younger population everywhere and most markedly in developing countries. Diabetes has reached epidemic proportions worldwide and this disease is at the forefront of public health challenges the world faces this century. The number of people around the world living with diabetes has skyrocketed in the last few decades and 422 million people were diagnosed with diabetes in 2014.
