Altered pulmonary ventilatory mechanics induced by Obesity

Abstract

The efficiency and functional status of lungs can be assessed by using the simple spirometric tests for effective diagnosis of various lung diseases. This study had objective of investigating alterations in respiratory function that is affected by obesity. 

Methods: The respiratory function tests were done  in  thirty obese adults  and  30   non obese adults  aged  between  30-50  years of both sexes.

Results: The results showed a trend in decreased response of FVC, FEV1 and FEV1%. However, FVC results were statistically not significant and FEV1 and FEV1% results are statistically significant. Trend in decrease in these variables in obese were suggestive of decreased efficiency of lungs.

Conclusion: Therefore, early detection of functional impairment of respiratory changes and its appropriate management is the only means by which the morbidity and mortality can be reduced.
