Chronic obstructive pulmonary disease (COPD) is a progressive lung disease characterized by airflow restriction, commonly resulting from smoking and environmental factors, leading to symptoms like cough, wheezing, and difficulty breathing. While there is no cure, management includes lifestyle changes, medications, and surgical options to improve quality of life. Patients with COPD are at higher risk for additional health issues and may require comprehensive care, including monitoring and education on self-management.
