Bronchospasm, Adult

ExitCare ImageA bronchospasm is a spasm or tightening of the airways going into the lungs. During a bronchospasm breathing becomes more difficult because the airways get smaller. When this happens there can be coughing, a whistling sound when breathing (wheezing), and difficulty breathing. Bronchospasm is often associated with asthma, but not all patients who experience a bronchospasm have asthma.


A bronchospasm is caused by inflammation or irritation of the airways. The inflammation or irritation may be triggered by:

  • Allergies (such as to animals, pollen, food, or mold). Allergens that cause bronchospasm may cause wheezing immediately after exposure or many hours later.  

  • Infection. Viral infections are believed to be the most common cause of bronchospasm.  

  • Exercise.  

  • Irritants (such as pollution, cigarette smoke, strong odors, aerosol sprays, and paint fumes).  

  • Weather changes. Winds increase molds and pollens in the air. Rain refreshes the air by washing irritants out. Cold air may cause inflammation.  

  • Stress and emotional upset.  


  • Wheezing.  

  • Excessive nighttime coughing.  

  • Frequent or severe coughing with a simple cold.  

  • Chest tightness.  

  • Shortness of breath.  


Bronchospasm is usually diagnosed through a history and physical exam. Tests, such as chest X-rays, are sometimes done to look for other conditions.


  • Inhaled medicines can be given to open up your airways and help you breathe. The medicines can be given using either an inhaler or a nebulizer machine.

  • Corticosteroid medicines may be given for severe bronchospasm, usually when it is associated with asthma.


  • Always have a plan prepared for seeking medical care. Know when to call your health care provider and local emergency services (911 in the U.S.). Know where you can access local emergency care.

  • Only take medicines as directed by your health care provider.

  • If you were prescribed an inhaler or nebulizer machine, ask your health care provider to explain how to use it correctly. Always use a spacer with your inhaler if you were given one.

  • It is necessary to remain calm during an attack. Try to relax and breathe more slowly.
