Relation of FEV1/FVC in Type 2 Diabetes Mellitus Patients

Aim and Objectives: To study the relationship of FEV1/FVC in type 2 diabetes mellitus patients by performing spirometry. Methods: Study included non - smoker, diabetic patients, who had no previous history of respiratory disease and undergone pulmonary function test by spirometry. This study included 100 such patients (50 male and 50 female). Spirovit schiller SP - 1 pneumotech flowsensor spirometer was used. FEV1/FVC was measured and analysed. It was an observational study. The study was conducted at Department of General Medicine, Shri Ram Murti Smarak Institute of Medical Sciences, Bareilly, Uttar Pradesh, India. Results: There was no significant derangement in the spirometric readings of FEV1/FVC of the diabetic patients. Only significant result was that as the duration of Diabetes mellitus increases the ratio decreases. The mean FEV1/FVC value was 73.28 % in male patients and while it was 79.46 % in female diabetic patients. In male diabetics with diabetes duration greater than5 years the mean FEV1/FVC value was 72.15 and in male diabetics with diabetes duration =/less than5 years the value was 75.27. In female diabetics with diabetes duration greater than5years the mean FEV1/FVC value was 77.98 and in female diabetics with diabetes duration =/less than5 years, the value was 81.30. p value was observed to be 0.240. In diabetics patients with diabetes duration greater than 5years, the mean FEV1/FVC value was 80.31 and in diabetics with diabetes duration=/less than5 years the value was 90.92. Conclusions: This study reveals non significant relation of FEV1/FVC with diabetic patients. There was no significant derangement in the spirometric readings of FEV1/FVC of the diabetic patients in this study in contrast to what was seen in other studies. There is a need for further study in this area, extending the study to a larger group.
