Chronic Obstructive Pulmonary Disease (COPD)
Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease that makes it difficult to breathe. It includes illnesses like emphysema and chronic bronchitis. People with COPD may have symptoms such as constant coughing, shortness of breath. It is caused by long-term exposure to lung irritants, such as cigarette smoke, air pollution, and occupational dusts. COPD reduces the ability of the lungs to expand and contract, leading to chronic bronchitis and emphysema. Symptoms include persistent coughing, wheezing, shortness of breath, and frequent chest infections.
