Diabetes mellitus is a chronic metabolic disorder of carbohydrate, protein and fat metabolism affecting all the systems in our body. Present study is designed to reveal the effects of diabetes mellitus on the pulmonary functions. Spirometry is a feasible tool to detect pulmonary function abnormalities at very early stage. The aim of present study is to record and compare pulmonary function tests in Type-2 Diabetes mellitus patients and apparently healthy control group. 60 cases of diabetics who had history of Diabetes mellitus for 5 years were enrolled for the study. In this study, there were a larger number of females than males (66.2% vs. 33.8%). The probable cause for this discrepancy was the fact that many males were excluded on account of their smoking history, alcohol intake, irresponsible behavior, busy working schedule while female diabetics were mostly eligible on account of their being non-smokers and other favoring factors. 60 age and sex matched healthy subjects served as controls. Forced expiratory spirograms were recorded by RMS medspiror. Lung function parameters such as forced vital capacity (FVC), forced expiratory volume in 1st second (FEV1), the ratio of FEV1/FVC, forced expiratory flow in the middle half of FVC (FEF 25-75%), peak expiratory flow rate (PEFR) were studied in both cases and controls. Student’s unpaired t-test was used to analyze the results obtained. Diabetic patients showed greater decline in FVC, FEV1, FEF 25-75%, PEFR and increase in FEV1/FVC ratio which is statistically significant, suggesting restrictive lung disorder.
