Can chronic obstructive pulmonary disease be cured completely

Chronic obstructive pulmonary disease (COPD) is a common clinical disease at present. The disease is mostly caused by the patient's long-term smoking history or long-term poor air quality environment, resulting in blocked gas exchange in trachea. The disease belongs to irreversible disease, so it cannot be cured. The disease can only be controlled by improving living habits and following doctor's advice.
