Scarring of the lung tissue happens over time, and the rate varies among individuals, explains the American Lung Association. There is no cure for interstitial pulmonary fibrosis, with death often occurring within three to five years after diagnosis.

Several factors increase risk for the condition, including smoking, viral infections, gastroesophageal reflux disease, family history of the pulmonary fibrosis and inhalation of environmental pollutants such as silica, hard metal dusts and fumes.

The disease contributes to the development of other conditions, including collapsed lungs, lung infections, respiratory and heart failure, cancer and blood clots in the lungs.
