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).
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself.lthough COPD shares similar characteristics with all other obstructive lung diseases, such as the signs of coughing and wheezing, they are distinct conditions in terms of disease onset, frequency of symptoms and reversibility of airway obstruction.
