What is aspiration pneumonia?
Aspiration (as-pi-RAY-shun) pneumonia (noo-MOH-nyah) happens when a liquid or an object is inhaled into the lungs. A common cause of aspiration pneumonia is inhaling (aspirating) acid or vomit from the stomach. Having food, drink, or saliva (spit) from your mouth go into your lungs can also cause aspiration pneumonia. When these things go into the lungs, it can damage (hurt) the lungs, or cause a blockage. This damage or blockage may cause swelling and fluid in the lungs. It can also cause an infection (in-FECK-shun) in the lungs, such as bacterial (bak-TEE-ree-al) pneumonia.
