Guide To Cough-Variant Asthma

Coughing is a common complaint; in fact, it is the most frequent grievance that drives patients to seek medical attention in the first place. Cough-variant asthma is a variety of asthma, one in which only coughing is a symptom. Cough-variant asthma is among the most common sources of chronic cough. More significantly, thirty to forty percent of adult patients who have cough-variant asthma, without being adequately treated, have a strong likelihood of progressing to classic asthma. The two types of asthma have several features in common, such as airway hyper-responsiveness, atopy, eosinophilic airway inflammation, as well as a variety of features of airways being remodeled.

Symptoms Of Cough-Variant Asthma

Cough-variant asthma is defined as a dry cough that does not expel any mucus as the only presenting symptom of the disease. Patients with cough-variant asthma lack classic asthma symptoms, including shortness of breath or wheezing. This condition is occasionally called chronic cough as it describes a cough that has been endured for longer than six to eight weeks. This coughing with asthma is capable of striking during the day or night, when it can disrupt sleep. Cough-variant asthma patients frequently observe their coughing increases during exercise, and this is often called exercise-induced asthma. When coughing increases is frequently when patients are exposed to triggers for asthma or allergy-causing substances such as dust or strong fragrances, or at times when withstanding cold air.
