Asthma is a chronic inflammatory disease associated with bronchial mucus hypersecretion (MBH) due to various mechanisms, such as increased mucin secretion, plasma exudation and cytokines. It is currently known that MBH in asthmatic patients is associated with increased mortality and reduced pulmonary function, but there is no tool for its objective assessment.~The aim of the study is to design and validate a questionnaire to objectively assess the level of bronchial mucus hypersecretion in patients with asthma.
