Many patients present with a dry cough as the only symptom, which is aggravated by encountering cold air stimuli or other irritating gases. The causes of allergies are numerous and complex, but there are two main areas of concern: the patient’s constitution and environmental factors. The patient’s constitution includes subjective conditions such as “hereditary qualities”, immune status, psychosomatic state, endocrine and health status, which are important factors in the patient’s susceptibility to allergic cough. Environmental factors, including allergens, irritant gases, viral infections, area of residence, living conditions, occupational factors, climate, medications, exercise (hyperventilation), food and food additives, dietary habits, social factors and even economic conditions may be more important factors in the development of allergic cough. The increasing trend in the incidence of allergic cough is also related to the susceptibility of patients due to their allergic constitution and to environmental factors.
