Chronic obstructive pulmonary disease (COPD) is a lung health condition characterized by blocked airflow, leading to symptoms such as chronic cough and shortness of breath. Major risk factors for COPD include smoking, exposure to second-hand smoke and pollutants, childhood lung infections, low socioeconomic status, and older age. Individuals with asthma are notably at higher risk for developing COPD, and it is important for at-risk groups to take precautions to prevent the disease.
