Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disorder characterized by persistent airflow limitation, chronic inflammation, and respiratory symptoms such as cough, dyspnea, and sputum production. COPD is a major cause of morbidity and mortality worldwide and significantly affects quality of life and economic productivity. The disease is primarily caused by tobacco smoking, exposure to air pollution, occupational dust, and genetic factors. Prevention and control of COPD are essential to reduce disease burden, improve patient outcomes, and decrease healthcare costs. Primary prevention focuses on smoking cessation, reducing environmental pollution, occupational safety, and public health education. Secondary prevention includes early diagnosis through spirometry, screening of high-risk populations, and timely medical intervention. Tertiary prevention aims to reduce complications and improve quality of life through pharmacological management, pulmonary rehabilitation, oxygen therapy, vaccination, nutritional support, and patient education. Effective control of COPD requires multidisciplinary collaboration involving healthcare professionals, government agencies, communities, and patients. This article discusses the causes, risk factors, clinical manifestations, preventive strategies, and comprehensive control measures for COPD along with the role of nurses and public health programs in disease management.
