What is chronic obstructive pulmonary disease (COPD)? #shorts

Chronic obstructive pulmonary disease (COPD) is a progressive lung disease that obstructs airflow, making it difficult to breathe. The main culprits are chronic bronchitis and emphysema, often caused by long-term exposure to irritating gases or particulate matter, most commonly from cigarette smoke. Symptoms include coughing, wheezing, shortness of breath, and chest tightness. COPD is a leading cause of disability and death worldwide. Management involves smoking cessation, bronchodilators, inhaled corticosteroids, and pulmonary rehabilitation. In severe cases, oxygen therapy or lung transplantation may be necessary.
