Interstitial lung disease

Overview

Interstitial lung disease may be caused by long-term exposure to hazardous materials, such as asbestos or coal dust, or an autoimmune disease, such as rheumatoid arthritis. Once lung scarring occurs, it's generally irreversible.

Symptoms

Symptoms include a dry cough and shortness of breath at rest or aggravated by exertion.

Treatments

Medications can slow the damage. A lung transplant may be an option for some people.
