Triggers

There are two different types of asthma: allergic (or extrinsic) asthma, and non-allergic (or intrinsic) asthma. Both types of asthma produce the same symptoms; the difference between the two is the factors that trigger the attacks.

Of the two types, allergic asthma is more common, affecting about 60% of all asthma sufferers. For allergic asthmatics, attacks are triggered by certain allergens, such as pollen, dust mites, mold, and animal dander. Most allergic asthmatics suffer from other allergy complications in addition to asthma: sneezing, itchy or watery eyes, and a runny nose, for example. Many allergic asthmatics find that the most effective treatments include general allergy medication in addition to asthma medication.

People with allergic asthma usually have a family history of allergies. They might also notice the severity of their condition varies with the seasons. For example, asthmatics who are allergic to pollen often have more attacks in the spring, when flowering plants are more abundant. There is also some evidence that indicates a relationship between asthma attacks and alcohol consumption, although the extent of this relationship is not yet clear.

Both allergic and non-allergic asthma attacks can be triggered by non-allergenic environmental factors, such as smoke, strong odors, cleaning products, perfumes, and chemicals. Unlike allergic asthma, the immune system is not involved in non-allergic asthma attacks. Because the triggers are not as clear and easily identifiable as those of allergic asthma, they can sometimes be more difficult to avoid. However, treatments for both types of asthma work in the same ways.
