Background and objectives:
Obesity is a common health problem all over the world and it is closely associated with many diseases that cause disturbances in the lung function. The objective of the present study was to assess the impact of increased body mass index (BMI) on the expiratory reserve volume (ERV).
Materials and Methods:
This study was conducted on 80 subjects of ages ranging from 25-40 years, of both the sexes. Of these, 40 were non-obese (BMI < 25 kg/mÂ²) and 40 were obese(BMI > 30kg/mÂ²). This study was carried out in the Department of T.B and Chest Diseases at the Infections Disease Hospital, Guntur, by using a computerized spirometer (Spiro-232, PK Morgan limited).
On the comparison of the results, the subjects with a BMI of more than 30 kg/mÂ² showed a decrease in ERV by 48.13%, than the normal subjects. Conclusion: An increased BMI resulted in decreased expiratory reserve volume and the changes were more marked in males than in the females.
