This can lead to&nbsp;shortness of breath, a dry cough, and other symptoms.</p> <p>Over time, untreated pneumonitis can lead to lung damage and a condition called pulmonary fibrosis, which can be life-threatening.</p> <p>Sometimes, the cause of pneumonitis&nbsp;is obvious, but in many cases, it's never found. <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/radiation.html/">Radiation treatments</a> and certain drugs can cause pneumonitis; more commonly, people get it from inhaling airborne dust containing certain types of <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/germs.html/">fungus or molds</a>. This is called <strong>hypersensitivity pneumonitis</strong>. It usually affects&nbsp;people who spend a lot of time around birds and farm workers&nbsp;who are exposed to dust from moldy hay and grain. For this reason, hypersensitivity pneumonitis is sometimes called "bird fancier's lung" or "farmer's lung."</p> <p>Treatment involves identifying the cause when possible and avoiding it. In chronic cases (those that go on for a long time), doctors may prescribe medicines to reduce inflammation in the lungs or fight infections.</p> <h3>Keep in Mind</h3> <p>In most cases, pneumonitis will clear up on its own if the cause can be identified and successfully avoided. Because long-term inflammation of the alveoli can lead to irreversible lung damage, it's important to&nbsp;talk to a doctor if anyone in your family has pneumonitis symptoms.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
Lungs and Respiratory SystemBy the time we're 70 years old, we will have taken at least 600 million breaths. All of this breathing couldn't happen without the respiratory system.https://kidshealth.org/ws/RadyChildrens/en/parents/lungs.html/6fe380c0-fe47-47a4-ba19-7e0944585a61
