A Model of Human Lungs

Do you have Hypersensitivity Pneumonitis?


This is an allergic reaction that causes inflammation in and around the air sacs of the lungs. This reaction can be caused by small organisms like dust, mold spores and chemicals.

Most people exposed to small amounts of these allergens will usually not have an reaction but large amounts over longer periods of time is when a reaction can occur which can cause permanent damage to the lungs.

When exposure is long term your immune system starts to react with the allergic reaction which can cause chronic inflammation and lung damage.


When a person has developed hypersensitivity to an allergen (in this case mold spores) their symptoms could be as follows

  • Fever
  • Cough
  • Chills
  • Shortness of breath

These symptoms can last a few days until contact with these allergens are gone. But complete recovery could take weeks. Hospitalization could be needed for people who are experiencing shortness of breath that isn’t going away.

If you have been exposed to an allergen that has caused an acute hypersensitivity pneumonitis episode one time, you should be able recover without treatments. But if exposure has been over a long period of time you probably need to see a Doctor about possible lung damage.
