When you have allergies, your body creates a response to something it thinks is a threat — the allergen. Your immune system fires up all of its defenses to try and fight off this danger. Your immune system releases various chemicals that cause inflammation, or swelling, and squeezing of your airways upon exposure to an allergen.
Allergic asthma is the most common type of asthma. In the United States, about 25 million people have asthma. Out of that group, approximately 60% have allergies.
If you have allergic asthma, you may have many of the same symptoms you’d experience with other types of asthma. These symptoms can include:

Allergy-induced asthma symptoms can range from mild respiratory symptoms to severe asthma attacks. During an asthma attack, your airways will tighten, making it difficult to breathe. You may also feel chest pressure, wheeze and cough. The symptoms of an allergic asthma attack are the same as an asthma attack caused by something else. The difference between the two is the cause of the asthma attack.
Allergens can be all around you — in your indoor and outdoor environments. When you have allergic asthma, inhaling these allergens can set off (trigger) your symptoms. It’s important to know what can trigger your asthma so that you can manage your condition.
