+ Further Information


While some people with asthma do not have any allergies (and a lot of people with allergies do not have asthma), most of the respiratory problems that occur during an asthma attack occur because a person has reacted to an allergen or irritant. Examples of allergens include dust mites, furry pets, cockroaches, and mold. Examples of irritants are environmental tobacco smoke and nitrogen dioxide.

Reducing a child's exposure to the factors to which he/she is allergic or bothered by can help decrease asthma symptoms. Click here to find out more information about Allergies, in general. Or click on one of the specific allergens or irritants below.
