Understanding Emphysema: Symptoms and Risks
Emphysema is a chronic lung condition caused by prolonged exposure to irritants like cigarette smoke and industrial fumes. It results in weakened lung tissue, reduced airflow, and symptoms such as wheezing, cough, and shortness of breath. Understanding these signs and avoiding irritants can help prevent severe lung damage and improve quality of life.
Emphysema develops from prolonged inhalation of irritants like cigarette smoke, industrial fumes, and environmental pollutants. These substances cause the smooth muscles in the airways to tighten permanently, while the mucus lining increases production to trap harmful particles. The body's response includes coughing to clear irritants, which can strain fragile alveolar walls, sometimes causing them to rupture. Over time, lung elasticity diminishes, reducing airflow and oxygen exchange. Symptoms often include wheezing, chest tightness, difficulty breathing, persistent cough, and fatigue. Advanced stages can lead to severe lung damage, infections, and reduced quality of life. Quitting exposure to irritants is crucial to slow progression and protect lung health.
