Chronic obstructive pulmonary disease (COPD) Alliance
COPD is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. It is a progressive condition that makes it increasingly difficult to breathe over time.
Overview
COPD is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. It is a progressive condition that makes it increasingly difficult to breathe over time.
Understand this condition
In a healthy body, air travels down the windpipe and into tiny air sacs that expand and deflate. With COPD, these sacs lose their elasticity or the walls between them are destroyed, trapping air in the lungs. This makes it difficult to get fresh oxygen in and carbon dioxide out.
Why it happens
Long-term irritation causes the airways to become inflamed and clogged with mucus. Over time, triggers like smog or smoke permanentlty scar the lung tissue and destroy the small air sacs. The disease progresses as the lungs have to work harder and harder to move air.
Real-world scenarios
- •This often appears as a persistent cough that produces significant mucus.
- •People may notice they get winded easily during simple household chores.
- •This often appears as frequent respiratory infections that take long to clear.
- •People may notice a wheezing sound when breathing during physical activity.
Common vs serious explanations
- •Temporary shortness of breath from poor physical fitness
- •Typical age-related changes in lung capacity
- •Minor respiratory infection causing a temporary cough
- •Seasonal allergies causing mild chest tightness
- Congestive heart failure causing fluid buildup in the lungs
- Pulmonary embolism or a blood clot in the lung
- Lung cancer obstructing the primary airways
- Acute pneumonia requiring hospitalization and oxygen therapy
