Interstitial Lung Disease

Interstitial lung disease is a term used to describe conditions which affect lung tissue and which do not usually affect the windpipes. In this group of conditions, the lung tissue is damaged in some way. The walls of the air sacs in the lung and the lung tissue become inflamed. If this inflammation continues then scarring, otherwise known as fibrosis, occurs and the lung becomes stiff. As lung tissue becomes scarred and thicker, it becomes more difficult for the lungs to transfer oxygen into the bloodstream. As a result, the brain, heart and other organs do not get the oxygen they need to function properly.
