Chronic obstructive pulmonary disease (COPD) is characterized by a progressive decline in lung function. This condition includes diseases such as emphysema and chronic bronchitis, which lead to breathing difficulties, reduced airflow, and persistent cough. COPD often results from long-term exposure to irritants, such as cigarette smoke or environmental pollutants. Managing symptoms is crucial; interventions can include lifestyle changes, medications, and pulmonary rehabilitation. Awareness and early diagnosis can positively impact the quality of life for individuals with this chronic disease.
