What Triggers Allergic Asthma?
Allergic asthma is the most common form of asthma, with symptoms resulting from reactions to triggers such as smoke, animal dander, pollen, insects, and more.
These triggers enter your system through your nose and mouth and travel down your throat. Normally, your body wouldn’t think they’re harmful. With allergic asthma, your body sees them as infectious invaders and begins to attack them. This immune system attack is what leads to symptoms.
What Happens Inside Your Body
A multi-step process in your body leads to common allergic asthma symptoms. An antibody called IgE is created the first time you’re exposed to an allergen. This is a molecule designed to fight foreign invaders.
IgE attacks and binds to the allergens upon second exposure. This releases chemicals that cause inflammation, swelling, and mucus in the trachea and bronchi, as shown.
In turn, you experience symptoms like chest tightness, shortness of breath, coughing, and wheezing.
Managing Your Symptoms
It’s not always possible to clean up and avoid triggers in the environments you visit. From time to time, even with the best asthma management, you’ll likely encounter something that will cause symptoms.
Having a plan is crucial in these cases. First, talk to your doctor about medications that can help you prevent symptoms, as well as options for when you do experience symptoms.
More importantly, take time to understand what your condition means. Understanding your peak expiratory flows and more will reveal strategies for living well with allergic asthma.
