Chronic obstructive pulmonary disease (COPD) is a chronic disease of the lungs that involves airway damage and blockage that worsens over time. The progressively worsening airway blockage causes the main symptoms of COPD: difficulty breathing, cough, and mucus production. While the most common cause of COPD is smoking, other causes can include significant exposure to air pollutants, frequent respiratory infections, and untreated asthma. Standard COPD treatments include use of specific inhalers to relax and open up the airways.
Chronic Obstructive Pulmonary Disease (COPD) falls under the Lungs & Breathing category.
