Allergic Asthma: Understanding the Connection to Allergies

Allergic asthma

Allergic asthma is a type of asthma that is caused by an allergic reaction. When a person with allergic asthma breathes in an allergen, such as pollen or dust mites, the immune system overreacts and produces antibodies called immunoglobulin E (IgE). These IgE antibodies bind to cells in the airways, called mast cells, which then release histamine and other chemicals. These chemicals cause the airways to become inflamed and narrow, making it difficult to breathe.

Symptoms of allergic asthma include:

* Wheezing

* Coughing

* Shortness of breath

* Chest tightness

* Itchy eyes, nose, or throat

* Runny nose

* Watery eyes

Allergic asthma can be diagnosed with a skin test or a blood test. Treatment for allergic asthma includes avoiding allergens, taking medication to control inflammation, and using quick-relief inhalers to relieve symptoms.
