One of the most prevalent non-communicable illnesses in the world is diabetes mellitus. Diabetes management in India confronts a number of difficulties, including increasing incidence in both urban and rural regions, a lack of public knowledge of the illness, inadequate health-care facilities, high treatment costs, poor glycaemic control, and a rising frequency of diabetic complications. Insulin treatment for diabetes is usually administered via subcutaneous injections four times a day. Patient compliance has been hampered by long-term insulin treatment, which is exacerbated by the intrusive nature of its delivery. This has influenced patient outcomes. Although Type 1 Diabetes is becoming increasingly common, the primary cause of the diabetic pandemic is type 2 diabetes mellitus that contributes for even more than 90% of all diabetes occurrences. Type 2 Diabetes is a severe and prevalent chronic illness caused by a complex interplay of genes and environment, as well as additional risk factors including obesity and a sedentary lifestyle.
