Chronic obstructive pulmonary disease, commonly known as COPD, is a progressive lung condition that significantly impacts the quality of life for millions worldwide. Characterized by persistent respiratory symptoms and airflow limitation, COPD is primarily caused by long-term exposure to harmful particles or gases, most notably from cigarette smoke. As a leading cause of morbidity and mortality, this disease poses a substantial public health challenge, often going undiagnosed until it has advanced due to its insidious onset and the commonality of its symptoms with other respiratory conditions. Understanding COPD is crucial for early detection and management, which can help improve patient outcomes and slow the progression of the disease.
