Interstitial lung disease is a group of lung conditions that causes scarring of lung tissues. I know a person who got interstitial lung disease because of his long-term exposure to asbestos. He often experienced shortness of breath at rest and dry cough. He tried many medications like a corticosteroid (prednisone), pirfenidone (Esbriet) and nintedanib (Ofev). He also used oxygen therapy to make breathing and exercise easier. However, his conditions were so severe that such treatments gave little results. His doctor suggested an option-lung transplantation. But the cost of such surgery are too expensive for him. He has long been held back by the disease. Bless him, bless all people who got interstitial lung disease!
