Background: Pulmonary function impairment among diabetic patients has rarely been studied. Hence, the present study was undertaken to analyze the impact of diabetes and glycemic control on pulmonary function tests (PFT). Materials and methods: A total of 120 patients were included in a cross-sectional study conducted at a tertiary care center in India. Formerly diagnosed diabetic patients with alteration in blood sugar levels were included. According to the duration of diabetes, there were three groups. Among all the patients, PFT was performed and correlated with the duration of the diabetic condition and glycated hemoglobin (HbA1c). Results: Significant decrease was observed in the mean value of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and peak expiratory flow rate (PEFR) in relation to their predicted values with preserved FEV1/FVC ratio, which is indicative of a restrictive pattern of ventilatory dysfunction. A significant negative correlation was found between the duration of diabetes, glycemic control, and PFT impairment. Conclusion: Long-term diabetes worsens pulmonary function impairment and poor glycemic control. Hence early screening of the respiratory system and strict glycemic control may help to prevent the progression of pulmonary dysfunctions among individuals with diabetes mellitus (DM).
