Abstract

In India, in recent decades there has been a simultaneous increase in the incidence of obesity and
pulmonary disorders. This study has therefore been carried out to reassess the pulmonary function values in
normal and obese Indian population and to check their variation in various pulmonary disorders. Forced
spirometry is one of the ways, which provides a written record of FVC, FEV1 and FEV1/FVC. In addition
to these parameters, BMI values are included to detect the potential severity of obstructive lung disorders.
