Objective: To study the prevalence of spirometric abnormalities and effects of age of onset, duration of disease, compliance and sex on spirometric parameters in diabetic patients. Methods: The present study was a hospital based cross sectional study. Patients selected were those attending medical OPD or admitted in medical wards. 100 patients who were known case of DM with duration more than 5 years were selected. Results: The mean FVC %, FEV1 % and FEV1 / FVC % was abnormal for age & sex insignificant percentage of cases. Study of spirometric values of patients with different age of onset and duration of disease did not revealed any decline in pulmonary function and their mean value of FVC%, FEV1% and FEV1 / FVC % were normal for age and sex. Also, there was no decline in pulmonary function in patients with relation of their sex. It was found that there was no decline in PFT in patients who were non-compliant & was not having good glycemic control. No decline in PFT was observed in patients who were obese and had BMI > 25 kg/m2 Conclusion: Routine screening for detection of PFT, which was found in few patients, could be because of ethnic factor or presence of early emphysematous change or due to diabetes incluced reduction in lung compliance and/ or reduced respiratory effort due to diabetes.
