This article provides an overview of chronic obstructive pulmonary disease (COPD), a progressive disease that affects millions of people worldwide. The primary cause of COPD is cigarette smoking, but environmental pollution, genetic predisposition, and occupational exposure to dust and chemicals can also contribute to its development. Symptoms include shortness of breath, wheezing, coughing, and chest tightness, and as the disease progresses, fatigue, weight loss, and frequent respiratory infections may occur. While there is currently no cure for COPD, quitting smoking and avoiding exposure to environmental pollutants can prevent further damage to the lungs. Treatment options include medications, oxygen therapy, and pulmonary rehabilitation programs. By taking steps to prevent and manage COPD, individuals can improve their overall health and quality of life.
