Allergies are all about your immune system. The job of your immune system is to protect you from germs such as bacteria and viruses. But if you have an allergy, your immune system will also defend your body against a harmless substance -- such as cat dander or dust mites -- that you encounter.
When you come across an allergy trigger, your body makes molecules called IgE antibodies. These trigger a series of reactions that can cause swelling, runny nose, and sneezing.
Bronchial thermoplasty is a treatment for severe asthma. It's a way to open your airways. The procedure uses gentle heat to shrink the smooth muscles in your lungs -- the ones that tighten during asthma attacks and make it hard to breathe.
You'll go to a hospital to get bronchial thermoplasty. It's given in three separate sessions with about 3 weeks between them. Each treatment lasts less than an hour, and a different part of your lungs gets treated each time.
Bronchial thermoplasty doesn't...
In people with allergic asthma, the muscles around their airways begin to tighten. The airways themselves also become inflamed and flooded with mucus.
Symptoms of Allergic Asthma
The symptoms of allergic asthma are generally the same as those of non-allergic asthma. They include:
Shortness of breath
Tightening of the chest
What Are Some Common Allergens?
Allergens you inhale are some of the most likely to worsen your allergic asthma.
Pollen from trees and grass, such as ragweed
Animal dander (from hair, skin, or feathers) and saliva
People may also have allergic reactions if they touch or eat allergens. This type of exposure rarely causes asthma symptoms, but it can cause a serious and even life-threatening reaction, such as anaphylactic shock, which makes it hard to breathe.
Irritants can also trigger an asthma attack, even though they don't cause an allergic reaction.
Strong chemical odors
Perfumes or other scented products
Intense emotions that cause you to laugh or cry
Your doctor might recommend allergy tests to figure out what allergens affect you. These tests usually involve pricking your skin with a tiny amount of the suspected allergen or injecting it under your skin. Your doctor then checks your skin for a reaction.
If a skin test isn't possible, you might get a blood test instead.
Avoid Your Allergic Asthma Triggers
When pollen counts are high, stay inside as much as possible. Keep the windows closed. If you have an air conditioner, use it to filter the air.
To keep dust mites out, wrap your pillows, mattress, and box springs in allergen-proof covers. Wash your sheets once a week in hot water.
