Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung condition characterized by obstructed airflow, making breathing difficult. It typically results from long-term exposure to irritants such as cigarette smoke, air pollution, or occupational dust. Symptoms include coughing, wheezing, shortness of breath, and chest tightness, which can significantly impact daily life. COPD encompasses conditions like emphysema and chronic bronchitis, with irreversible damage to the airways and lung tissue. While there's no cure, treatment aims to relieve symptoms, improve quality of life, and slow disease progression through medication, pulmonary rehabilitation, oxygen therapy, and lifestyle changes like quitting smoking. Early diagnosis and management are crucial in minimizing complications and enhancing overall well-being for individuals living with COPD.
