What is Restrictive Lung Disease?
Restrictive Lung Disease (chest wall diseases) can result from different problems, including interstitial fibrosis, scoliosis (spine curvature) and sarcoidosis. Some cause scarring in the lungs, while others compress the lungs. Some have no known cause; other causes include occupational exposure, chemotherapeutic agents or radiation, and connective tissue diseases such as lupus or rheumatoid arthritis.
• Restrictive lung diseases are characterized by reduced lung volume, either because of an alteration in lung parenchyma or because of a disease of the pleura, chest wall, or neuromuscular apparatus. In physiological terms, restrictive lung diseases are characterized by reduced total lung capacity (TLC), vital capacity, or resting lung volume. Accompanying characteristics are preserved airflow and normal airway resistance, which are measured as the functional residual capacity (FRC). If caused by parenchymal lung disease, restrictive lung disorders are accompanied by reduced gas transfer, which may be marked clinically by desaturation after exercise.

These disorders are caused by defects in type II or type XI collagen. Collagens are complex molecules that provide structure, strength, and elast
Restrictive lung disease, a decrease in the total volume of air that the lungs are able to hold, is often due to a decrease in the elasticity of the lungs themselves or caused by a problem related to the expansion of the chest wall during inhalation. Examples of restrictive lung diseases include asbestosis, sarcoidosis and pulmonary fibrosis.
