Allergy and Asthma

Can asthma be caused by allergies?

The same substances that trigger your hay fever (allergic rhinitis) symptoms, such as pollen, dust mites and pet dander, may also cause asthma signs and symptoms. In some people, skin or food allergies can cause asthma symptoms. This is called allergic asthma or allergy-induced asthma.

Allergic asthma is a breathing condition where the airways you breathe through tighten when you inhale an allergen. Common allergens include pollen, dander and mold spores. This type of asthma is very common in both children and adults. Symptoms of allergic asthma can include shortness of breath, coughing, wheezing, stuffy nose, itchy eyes and a rash.
