What is cough-variant asthma?

ANSWER

Cough-variant asthma is a type of asthma in which the main symptom is a dry, non-productive cough. (A non-productive cough does not expel any mucus from the respiratory tract.) People with cough-variant asthma often have no other "classic" asthma symptoms, such as wheezing or shortness of breath. Cough-variant asthma is sometimes called chronic cough to describe a cough that has lasted longer than six to eight weeks. The coughing with asthma can occur during the day or at night. If you have nighttime asthma, it can interrupt sleep. People with cough-variant asthma often notice that coughing increases with exercise, called exercise-induced asthma. Coughing may increase when they are exposed to asthma triggers or allergy-causing substances like dust or strong fragrances, or when they are in cold air.
