It depends. Some people can recover from hypersensitivity pneumonitis, but others may die from it. It depends on your overall health, how much scarring is in your lungs, and if you can avoid what caused it in the first place.

If you have hypersensitivity pneumonitis, you may have a lower life expectancy. For many people, that means you probably won’t live as long as you would if you didn’t have it. It’s hard to predict exactly how long you will live. Some studies have found that people lived for 18 years. Some have found that people only lived 3 years.

The most important factor in how long you can live with hypersensitivity pneumonitis is your lung health. If you have a lot of scarring, called fibrosis, you probably won’t live as long. If you were able to figure out the cause, it’s also important that you avoid it. Avoiding what caused it can improve your lung health and may help you live longer.

If you have other serious health conditions, like an autoimmune disease, you probably won’t live as long. If you don’t have many other health conditions and are pretty healthy, you can live for many years.

Follow your doctor’s advice and treatment plan and take your medications. That’s your best bet for staying as well as you can for as long as you can.


Lots of things affect how long you’ll live, so a prediction is hard to give.
