About Idiopathic Pulmonary Fibrosis

Idiopathic pulmonary fibrosis is a medical condition of unknown etiology with poor prognosis in which progressive fibrosis of the alveolar walls produces irreversible "honeycomb lung*". In general, restrictive impairment (reduction of vital capacity (VC) and total lung capacity (TLC)) is evident. As the symptom (fibrosis of the alveolar walls) progresses, gas exchange in the lungs (exchange of oxygen and carbon dioxide) becomes difficult. In some cases, oxygen therapy becomes necessary. Because of
its severity, IPF is designated as a "specified disease" (in other words, an intractable disorder).
