Frequently Asked Questions

Are allergies and asthma related?

Yes, they can be related. Allergies and asthma often occur together. Substances that trigger allergic rhinitis, such as pollen, dander, and mold spores, can also cause asthma. In some people, even skin or food allergies can cause asthma symptoms.

Symptoms of allergic asthma can include shortness of breath, coughing, wheezing, stuffy nose, itchy eyes, and a rash.

Can allergies and asthma occur together?

Asthma is a disease of the lungs that causes your airways to become swollen and irritated. Your airways may also become narrow because the muscles around the airways tighten.

When you have allergies, your body fires up all its defenses to try and fight off danger. Your immune system releases a chemical called immunoglobulin E (IgE), which is used to fight the threat. However, high amounts of IgE can cause your airways to tighten, making breathing difficult and ultimately resulting in allergic asthma.

What allergies are linked to asthma?

Substances that trigger your allergies can also trigger asthma. Inhaling an allergen (something you are allergic to) can cause asthma symptoms. If you have identified your allergens, avoid or limit contact with them to prevent an asthma episode.

Common inhaled allergens that cause allergic asthma include:

  • Dust mites
  • Cockroaches
  • Pollen
  • Molds
  • Pet dander
  • Rodents

Although less common, food allergies can also sometimes cause asthma. Food allergies, however, are known to cause a severe life-threatening reaction called Anaphylaxis, where your airways are swollen and blocked. Immediate emergency care is critical in such cases.

Can allergies make your asthma act up?

Yes. Allergies and asthma often occur together.

If you are exposed to an allergen that causes your airways to swell up or tighten, it can trigger an asthma attack.

How can you tell the difference between allergies and asthma?

There are different types of asthma. One such type is called allergic asthma.  The difference between allergies and asthma lies in the location of the reaction.

If the reaction happens in your nose, your symptoms will likely include congestion and sneezing. However, if the reaction occurs in your lungs, your symptoms will likely include coughing, wheezing, and shortness of breath. These are all signs of an asthma attack.

Do you provide allergy testing?

Yes, we provide a variety of allergy testing options at West Hills Allergy & Asthma Associates. This includes:

  • Allergy Skin Test

  • Allergen Patch Testing
