Information for Patients

Bronchial Disorders

The bronchi are two tubes that branch off the trachea, or windpipe. The bronchi carry air to your lungs.

The most common problem with the bronchi is bronchitis, an inflammation of the tubes. Bronchitis can be acute or chronic. Other problems include

  • Bronchiectasis, a condition in which damage to the airways causes them to widen and become flabby and scarred
  • Exercise-induced bronchospasm, which happens when the airways shrink while you are exercising
  • Bronchiolitis, an inflammation of the small airways that branch off from the bronchi
  • Bronchopulmonary dysplasia, a condition affecting infants

Treatment of bronchial disorders depends on the cause.

  • Bronchiectasis
  • Bronchiolitis
  • Bronchiolitis - discharge
  • Bronchopulmonary dysplasia
  • Postural drainage
  • Tracheal rupture
