Interstitial lung disease describes a large group of disorders, most of which cause progressive scarring of lung tissue.
The scarring associated with interstitial lung disease eventually affects your ability to breathe and get enough oxygen into your bloodstream.
Once lung scarring occurs, it’s generally irreversible. Medications may slow the damage of interstitial lung disease, but many people never regain full use of their lungs. Lung transplant is an option for some people who have interstitial lung disease.
