Materials and Methods: The present study is a hospital-based cross-sectional study. A pre-designed, pre-tested, and semi-structured questionnaire, “MOS SF-36 v 2” was used to determine the quality of life of the study participants. Results: MALE participants had higher quality of life scores, when compared to female participants with 68.54 ± 15.41 and 53.87 ± 14.12 scores respectively. This difference was found to be statistically significant.The quality of life was higher in patients with normal BMI when compared with patients with obesity or over weight which was statistically significant. The quality of life in patients with longer duration of the diabetes was poorer when compared to the patients with shorter duration of diabetes. The quality of life in patients with comorbidities was poorer when compared to the patients with shorter duration of diabetes. Conclusions: The quality of life is compromised in the diabetics who were females and had co morbidities, with longer duration of diabetes and the patients who were overweight
