  Background: The aim of this cross-sectional study was to determine the frequency of small airways obstruction in obese patients referred to obesity clinic of the Hazrat-e-Rasool Akram Hospital during 2011-12.   Methods : Retrospectively, the frequency of Small Airway Disease (SAD) in 100 adult obese patients, who had no history of respiratory or cardio-respiratory disorders and did not complain about respiratory problems in recent weeks, and was determined in people with forced expiratory flow at 25-75% of the pulmonary volume (FEF25-75%) less than 60%.   Results: The average age was 40.3 ± 8.6 years. Twenty-eight percent of subjects were found to suffer from SAD, of those 86% were women and 14% were men.   Conclusions: The small airways disease prevalence was found higher in obese than non-obese people. Thus, to reduce the mortality and morbidity it would be recommended to diagnose the pulmonary disorders in obese people.
