Pulmonary Emphysema

What is pulmonary emphysema?

Emphysema is a chronic lung condition in which the air sacs (alveoli) may be:

  • Destroyed
  • Narrowed
  • Collapsed
  • Stretched
  • Overinflated

Overinflation of the air sacs is a result of breakdown of the walls of the alveoli. It causes a decrease in respiratory function and breathlessness.

Damage to the air sacs is irreversible and results in permanent "holes" in the tissues of the lower lungs.

Pulmonary emphysema is part of a group of lung diseases called chronic obstructive pulmonary disease (COPD). COPD lung diseases cause airflow blockage and breathing problems. The two most common conditions of COPD are chronic bronchitis and emphysema.

What causes pulmonary emphysema?

Emphysema does not develop suddenly, but occurs very slowly over time. It’s caused by:

  • Smoking. This is the main cause.
  • Exposure to air pollution, such as chemical fumes, dust, and other substances
  • Irritating fumes and dusts at work
  • A rare, inherited form of the disease called alpha 1-antitrypsin (AAT) deficiency-related pulmonary emphysema, or early onset pulmonary emphysema. AAT is produced by the liver and is a "lung protector." Nearly all people without AAT develop emphysema.
