How widespread are Restrictive Lung Diseases?
• Intrinsic Lung Diseases Exposure to environmental pollutants (dust, organic solvents, pesticide aerosols, etc.) increases one’s risk of developing intrinsic lung diseases such as idiopathic pulmonary fibrosis (about 30 cases per 100,000), or sarcoidosis (about 20-40 cases per 100,000 persons.) • Extrinsic Respiratory Disorders Kyphoscoliosis is a common extrinsic disorder. Mild deformities related to Kyphoscoliosis are found in 1 out of every 1000 persons, with severe deformity found in 1 out of every 10,000 persons.
