ABSTRACT
Introduction: The Pulmonary function tests in subjects withnormal BMI and with obese individuals were done andcorrelated with the severity of obesity. Considering the PFTchanges, normal study was present in 17%. But, remainingindividuals showed proportionate decrease in both FEV1 andFVC values. These changes were independent of age, sex andblood pressure.Methods and Results: Selection of the Subjects Obeseindividuals of about 30 people with BMI >30 of both sexes ofage group between 30 -45 years were included in this study.The healthy volunteers, visitors or relatives of patients visitingS. P. Medical College Hospital, Bikaner Rajasthan were takenas subjects. So, the PFT changes are more of restrictive thanobstructive pattern which can leads to decreased chest walland lung compliance, respiratory muscle strength andendurance which ultimately ends in poor pulmonary ventilation.Hence, this non-invasive procedure may be utilized as aroutine screening test for obese people for better medical care.Conclusion: Thus, obesity is associated with a wide variety ofPFT abnormalities, many of which can be corrected by weightloss
