Effect of weight reduction on obese patients with COPD and bronchial asthma

There is a link between obesity and both, asthma and COPD. Aim of the work: To study effect of weight reduction on pulmonary function tests of obese COPD and bronchial asthma patients. Subjects and methods: 2 groups were included, group(G) I, 30 obese COPD and GII 30 obese bronchial asthma patients. Pulmonary function tests were done to all participants before and after weight reduction. Results: GI showed increased FRC, ERV and RV significantly, IC was significantly decreased and GII showed increased FEV1, FVC, FEV1/FVC, PEFR, FEF25-75% and ERV significantly after weight reduction. Conclusion: Weight reduction improved airway obstruction, increased ERV, RV, FRC and DLCO either significant or insignificant in asthma and COPD. (C) 2015 The Authors.
