A: allergic cough cough is the respiratory allergens caused by stimulation of the body, its characteristics are caused by exposure to allergens is paroxysmal nocturnal dry cough, sputum less out of allergen in cough more light, or cough. If prolonged exposure to sensitizing substance or exposure to strong allergen, can also cause Hypersensitivity Pneumonitis.
Common allergens causing allergic cough endogenous and exogenous can be divided into two broad categories. Endogenous allergens such as roundworm larva, hookworm larvae within the trachea and lungs when the migration can cause allergic cough. Of exogenous allergic original dust, pollen, animal fur, feathers, paints, chemical fiber fabrics, drugs. Your daughter the day cough less heavy cough at night, cough worse at night. Therefore, should consider the child\'s sleep environment run minyuan, such as the replacement of chemical fiber bedding, indoor flowers, keeps pets, newly renovated the House or for a new furniture.
Allergic cough with antiallergic drug, only temporarily alleviate the symptoms, not disarmament cause. For example, child is allergic to dog hair cuttings, although eating antiallergic drug, still contact the dog every day, cough will not stop. Therefore, we recommend that you find about allergens, or go to the hospital detected the allergen. As long as the child does not contact sensitizer, even without drugs will heal.
