Background: Diabetes is a chornic disease that affects 463 million people world wide over the age of 20 years and is expected to affect more than 570 million by 2030. Like other organs, lung is also affected in diabetes mellitus due to the presence of extensive microvasculature and abundant connective tissue. (1) The prevalence of defective pulmonary function in asymptomatic diabetic patients is more than generally thought, involving 60% of adult cases. Early detection of pulmonary changes in diabetic patients through routine Pulmonary function testing (PFT) check-up may help in planning strategies to delay the progression of cardio-respiratory complications Hence the present study was planned to assess the pulmonary functions in the Pre-diabetes. Aim: This study was conducted to determine the pulmonary function test parameters like FVC, FEV1 in Pre-diabetes. Materials and Methods: This study was conducted in the teaching hospital of Adichunchanagiri Institute of Medical Sciences (AIMS), B.G. Nagara, Mandya after the institutional ethical clearance and written consent from each participant. The present study was a case control study consisting of 30  cases and 30 controls in the age group of 20-40 years. FVC and FEV1was recorded. Results: The parameters thus recorded was analyzed for statistical significance using Students‘t’ test and p <0.05 was considered the level of significance. FVC and FEV1 were significantly decreased at (p < 0.001**) in the the Pre-diabetes. Conclusions:  The results of this study indicate that pulmonary function test is  decreased in the Pre-diabetes stage itself
