What is effected: Asthma is a disease of chronic mid to small airway inflammation, sometimes caused by allergens but not always. Hypersensitivity pneumonitis is inflammation of the lung tissue itself as the result of exposure to allergens (eg birds) , it usually resolves when the allergen is removed, although long term exposure can lead to scarring.
