Understanding, Managing, and Living with COPD

Definition and Overview** Chronic Obstructive Pulmonary Disease (COPD) is a **chronic inflammatory lung disease** that obstructs airflow, making breathing difficult. It is **progressive**, meaning it worsens over time, and is primarily caused by long-term exposure to irritants such as cigarette smoke. COPD includes two main conditions: - **Emphysema**: Damage to the alveoli (air sacs), reducing lung elasticity. - **Chronic Bronchitis**: Persistent inflammation of the bronchial tubes, leading to mucus buildup.
