What is COPD?

COPD is a group of lung diseases that most usually includes chronic bronchitis, emphysema, or both.

  • Chronic bronchitis: the swelling of the main airways in the lungs. The airways also produce more mucus than normal.
  • Emphysema: damage to the air sacs in the lungs. Damaged air sacs cannot be repaired.

COPD is a lung disease that causes problems with your breathing. These breathing problems occur when your lungs have trouble bringing in healthy new air or pushing “used” air out.

  • Chronic – persistent, doesn’t go away
  • Obstructive – partly blocks the flow of air from the lungs
  • Pulmonary – pertains to the lungs
  • Disease – a sickness
