COPD (Chronic Obstructive Pulmonary Disease)

COPD is a lung disease that makes it hard to breathe. It is caused by damage to the lungs over many years, usually from smoking.

COPD is often a mix of two diseases:

  • Chronic bronchitis (say "bron-KY-tus"). In chronic bronchitis, the airways that carry air to the lungs (bronchial tubes) get inflamed and make a lot of mucus. This can narrow or block the airways, making it hard for you to breathe.
  • Emphysema (say "em-fuh-ZEE-muh"). In a healthy person, the tiny air sacs in the lungs are like balloons. As you breathe in and out, they get bigger and smaller to move air through your lungs. But with emphysema, these air sacs are damaged and lose their stretch. Less air gets in and out of the lungs, which makes you feel short of breath.

COPD gets worse over time. You can't undo the damage to your lungs. But you can take steps to prevent more damage and to feel better.
