What’s the difference between allergic asthma and non-allergic asthma?
Allergic asthma is a type of asthma. In lots of people, asthma and allergies go hand-in-hand. This means that if you have allergies, you’re more likely to have asthma, and vice versa. However, allergic asthma and non-allergic asthma are not the same condition.
Symptoms of any type of asthma are caused by the narrowing of your airways. Your airways narrow as a result of getting inflamed or irritated, usually in response to an infection.
Allergic-asthma is triggered when you come into contact with something you’re allergic to (called an ‘allergen’), such as pollen. The allergen will trigger your asthma symptoms wherever you are sensitive to it, like in your nose or chest.
Non-allergic asthma is when your asthma symptoms are caused by an irritant that you breathe into your airways, but not by an allergic reaction.
Day-to-day irritants can include: cigarette smoke, or car exhaust fumes. It can also be triggered by factors such as cold weather, exercise, or a common cold. Symptoms of non-allergic asthma only affect your chest and lungs.
