1 Interstitial lung disease, such as idiopathic pulmonary fibrosis. 2 Sarcoidosis, an autoimmune disease. 3 Obesity, including obesity hypoventilation syndrome. 4 Scoliosis. 5 Neuromuscular disease, such as muscular dystrophy or amyotrophic lateral sclerosis (ALS).
The most common causes of obstructive lung disease are: 1  Chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis. 2  Asthma. 3  Bronchiectasis. 4  Cystic fibrosis. Some conditions causing restrictive lung disease are: 1  Interstitial lung disease, such as idiopathic pulmonary fibrosis. 2  Sarcoidosis, an autoimmune disease. 3  Obesity, including obesity hypoventilation syndrome. 4  Scoliosis. 5  Neuromuscular disease, such as muscular dystrophy or amyotrophic lateral sclerosis (ALS). Restrictive Lung Disease. Restrictive lung disease is a chronic disorder that causes a decrease in the ability to expand the lung (breathe in) and sometimes makes it harder to get enough oxygen to meet the body's needs. The most common restrictive lung diseases are: The volume of FRC is determined by the balance of the inward elastic recoil of the lungs and the outward elastic recoil of the chest wall. Restrictive lung diseases are characterized by a reduction in FRC and other lung volumes because of pathology in lungs, pleura, or the structures of the thoracic cage. Unlike obstructive lung diseases, including asthma and COPD, which show a normal or increased total lung capacity (TLC), restrictive disease are associated with a decreased TLC. Measures of expiratory airflow are preserved and airway resistance is normal. Obesity is becoming a major cause of restrictive lung disease in the developed world. Over 30% of American adults are classified as obese, with a BMI greater than 30. There is an inverse relationship between BMI and lung volumes. Their lungs are restricted from fully expanding. Restrictive lung disease most often results from a condition causing stiffness in the lungs themselves. In other cases, stiffness of the chest wall, weak muscles, or damaged nerves may cause the restriction in lung expansion.
