Chronic obstructive pulmonary disease (COPD) is a chronic and progressive illness characterized by an irreversible decrease in airflow.
The origin of this loss of breath is the permanent and progressive narrowing of the bronchial tubes resulting from constrictive scarring of the airways and their collapse linked to loss of lung tissue. Little by little, this bronchial obstruction prevents the passage of air, resulting in shortness of breath. This initially occurs with physical exertion, then gradually under conditions less and less physically intense, and finally difficulty breathing occurs even at rest.
