Pulmonary function test in patients of type 2 diabetes mellitus

ABSTRACT

Background: We are today witnessing a pandemic of diabetes mellitus (DM), globally and nationally. DM and its complications have become the most important contemporary and challenging health problems. Diabetes is not associated with any specific pulmonary symptom and hence periodic screening for lung disease is not done in diabetic patients. However, an extensive microvascular circulation and an abundant connective tissue in the lung raise the possibility that the lung may also be a target organ in diabetic patients. The aim and objectives were to study the pulmonary function of individual with type 2 diabetes mellitus patients by performing spirometry.Methods: Study included non-smoker diabetic patients, who had no history of respiratory disease, were selected for this study and undergone pulmonary function test by spirometry. The study was conducted at department of General Medicine Shri Ram Murti Smarak Institute of Medical Sciences, Bareilly, Uttar Pradesh, India.Results: Present study, author found that there was significant derangement in the spirometric readings in the diabetic patients. The FEV1/FVC values further declines as the duration of diabetes increased.Conclusions: Spirometric values (FVC, FEV1, FEV1/FVC) were consistently lower in subjects with type 2 diabetes mellitus. The effect on FVC predicted % was found to be more pronounced in subjects whose duration of DM was more than 5 years.
