PURPOSE: Obesity increases the risk of asthma and contributes to a more difficult-to-control phenotype of the disease. In spite of the compelling evidence of association between asthma and obesity, relation between the BMI and increased airway/bronchial hyper-responsiveness (AHR/BHR) which is the basic physiological abnormality in asthma, has shown conflicting results. Provocative concentration of methacholine that reduces FEV1 by 20% (PC20) is a measure of AHR used in diagnosis of asthma. This study is aimed at exploring the relationship between BMI and PC20 in individuals suspected to have asthma, whose airways are hyper-responsive to methacholine.
