Diabetes is a group of disorders characterized by high glucose levels that cause unique eye, kidney, and nerve complications and an increased risk for cardiovascular disease. These factors contribute to an increased risk of illness and death which places a significant burden on health care system. A prospective observational study was carried out for a period of three years with the aim to determine prevalence of diabetic complications. A total of 400 patients were enrolled in the study with the inclusion criteria of patients with past history of diabetes as well as newly diagnosed cases. The study showed that diabetes is more prevalent in females than males and also found a higher prevalence of the disease among elderly patients. The study revealed the presence of more macrovascular complications like hypertension, IHD, dyslipidaemia and stroke. Adequate metabolic control may help to reduce the risks of complications over the long term. This also improves the quality of life with diabetes and reduces the burden on health care systems.
