Pulmonary Fibrosis

Idiopathic pulmonary fibrosis is an inflammatory lung disorder of unknown origin (idiopathic) characterized by abnormal formation of fibrous tissue (fibrosis) between the tiny air sacs (alveoli) or ducts of the lungs. Coughing and rapid, shallow breathing occur with moderate exercise. The skin may appear slightly bluish (cyanotic) due to lack of circulating oxygen. Complications such as infection, emphysema or heart problems may develop.
