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 workTo study effect of weight reduction on pulmonary function tests of obese COPD and bronchial asthma patients.Subjects and methods2 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.ResultsGI 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.ConclusionWeight reduction improved airway obstruction, increased ERV, RV, FRC and DLCO either significant or insignificant in asthma and COPD.
