A silent pandemic known as diabetes mellitus (DM) is fast spreading around the world, adding significantly to the burden of non-communicable diseases that are mostly supported by immobile lifestyles, ageing populations, urbanisation, and rising obesity rates. It is understood that the prevalence of diabetes has increased as a result of economic development, modern lifestyles, and more urbanised civilizations. In the twenty-first century, both industrialised and developing countries have come to view diabetes mellitus as a persistent health burden that is causing havoc and concern among health specialists. It is a global problem with devastating effects on people, society, and the economy that affects almost 300 million people globally. International Diabetes Federation (IDF) collects and analyses data on the occurrence and prevalence of diabetes from important studies conducted all over the world, which are then published in the International Diabetes Federation twice a year.
