تعريف

Chronic obstructive pulmonary disease (COPD) is a long-term lung disease. COPD makes it difficult to move air in and out of the lungs. It will make breathing difficult. COPD includes:

  • Emphysema—air sacs of lungs are damaged
  • Chronic bronchitis—airways of lungs are damaged

The changes to lung tissue differ with the two diseases. However, they often occur together. The causes and treatment of each condition are similar.
