Cough Variant Asthma is a Unique Form of Asthma

Cough Variant Asthma is a type of asthma that gets its name from its only symptom. With other types of asthma there is a set of asthma symptoms that are very typical. The difference with all asthma types is not usually in what symptoms you have, but what causes those symptoms. However, there is no typical list of causes, even for the same type of asthma.

Cough Variant Asthma Is Different

Instead of the usual four symptoms, with cough variant asthma coughing is the only symptom. And instead of the usual asthma cough, this cough is a very dry cough with no mucus being expelled. This cough can also last for a long time, perhaps for many weeks. It can also be a loud cough, what is called a barking cough. Since there are no other symptoms like wheezing, chest tightness, or shortness of breath, this type of asthma often goes undiagnosed.

What is Asthma

Having any type of asthma, such as cough variant asthma, means that your airways or breathing tubes going to your lungs are very sensitive to specific things. These things are called your asthma triggers. Coming into contact with any of these things will cause your airways to get really upset. And when the airways of a person with asthma get upset, there is a very predictable list of things that usually happen.

• There is swelling on the inside of your airways which makes them smaller.


• The muscles on the outside of your airways try to squeeze the airways shut, making them even smaller.


• The inside of your airways create gunk (plegm or mucus are other words used) which clogs up the airways even more.

With cough variant asthma, your airways do get irritated but not with the same results. They don't become so small so that you have trouble breathing and the muscles around the airways don't appear to tighten up so you don't feel the tightness in the chest. There is also no gunk being produced inside of the airways. The only symptom is the very persistent cough.

Asthma Triggers

If you have cough variant asthma, your asthma causes or triggers responsible for your chronic cough are similar to the triggers for other types of asthma. If you have asthma, you will have your own personal list of things that your airways really hate. If you come in contact with or do any of those things on your list, your airways will get really irritated. In the case of cough variant asthma, the result will be your chronic cough. The following things are a partial list of possible asthma triggers that might be on your list:

• Specific foods - could pretty much be anything


• Different types of air pollution


• Aerosol sprays - like hair spray or deodorants, etc


• Pet dander - all pets give off dander


• Cockroach droppings


• Dust mites - in your bedding, carpets, etc


• Allergens - like grass or pollen, etc


• Mold - both indoor and outdoor


• Smoke - all types


• Weather - could be certain types of weather or changes in the weather


• Stress - or other strong emotions


• and the list goes on

Anything on the above list could could be one of your asthma triggers. In fact, you could have any number of those things on your list. You might even have a trigger that is not on that list. Everybody has their own list and the way that you are affected by something on the list will be different from the way that it affects somebody else. Some people with asthma have their airways get irritated all the time while others only see the problem every once in awhile.
