Expiratory dyspnea may result from lesions affecting the bronchi and bronchioles, and may also be associated with alveolar pathology. Additionally, spasm or narrowing of the smallest airways can readily lead to this symptom. Moreover, patients with severe bronchiectasis or bronchial asthma may experience expiratory dyspnea of varying severity during acute exacerbations.
