What Is Cough-Variant Asthma? 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 guidelines 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.
Who Gets Cough-Variant Asthma? Anyone can get cough-variant asthma at any time, but it is common in young kids with childhood asthma.
Cough-variant asthma may lead to the development of "classic" asthma, with symptoms that include shortness of breath and wheezing. What Causes Cough-Variant Asthma? Like "classic" or "typical" asthma, no one really knows what causes cough-variant asthma.
However, coughing may start after people are exposed to allergens, or when they are breathing in cold air.
Coughing may also follow an upper respiratory infection. For example, sinusitis with asthma is common.
In addition, a cough that begins after a person has begun taking beta-blockers is likely to be cough-variant asthma. Beta-blockers are drugs used to treat high blood pressure, heart disease, heart failure, migraines, palpitations, and other conditions. Beta-blockers are also found in eye drops to treat glaucoma and other eye problems.
