By definition;
Bronchiectasis is primarily considered an obstructive lung disease, as inflamed, damaged airways become floppy and filled with mucus, making it hard to get air out (airflow obstruction), but it can also have restrictive features, especially in severe cases with atelectasis (collapsed lung tissue) or fibrosis, where the lung can't fully expand. It's often a mix, but the hallmark is airway obstruction, leading to cough and sputum.
