In response to the allergen, your body makes a protein called IgE, which grabs onto the allergen. Chemicals including histamine are released into your blood and cause the symptoms you experience. As the AAAAI explains:
“Each type of IgE has specific ‘radar’ for each type of allergen. That’s why some people are only allergic to cat dander (they only have the IgE antibodies specific to cat dander); while others have allergic reactions to multiple allergens because they have many more types of IgE antibodies.”
What are the most common types of allergic diseases?
There are many different forms of allergic diseases, and it’s possible to experience more than one.
Allergic rhinitis often involves year-round symptoms including nasal congestion, sneezing and itchy eyes and mouth. It is frequently triggered by exposure to indoor allergens such as dust mites, indoor molds or pets. WebMD reports that 100 percent of all U.S. households have detectable levels of dog and cat dander, the tiny flecks of skin shed by all animals with fur and feathers. Studies show that 80 percent of the homes in the United States have detectable levels of dust mite allergen in at least one bed.
Seasonal Allergic Rhinitis
Seasonal allergic rhinitis, or “hay fever,” usually occurs in the spring, summer or fall and is triggered by the pollens, weeds, mold and grasses that bloom throughout the seasons.
Asthma is a chronic lung disease characterized by difficulty breathing caused by inflamed, narrowed bronchial tubes. Up to 78 percent of those with asthma also have allergic rhinitis.
occurs when the eyes come in contact with allergens and turn red, itch and swell.
Urticaria, or hives, is often triggered by medications
, foods or insect stings and are characterized by large or small itchy, red bumps.
Atopic Dermatitis (Eczema)
Atopic dermatitis, or eczema, typically happens when your skin comes in direct contact with an allergen. You may experience reddening, itching and flaking or peeling. Symptoms arise in childhood for 80 percent of people with eczema, and 50 percent of these people also develop asthma.
Food allergies are caused by the immune system’s overreaction to a particular substance found in a food. Eight foods are responsible for 90 percent of the food allergies: the proteins in cow’s milk, eggs, peanuts
, tree nuts, wheat, soy, fish and shellfish.
What are some seasonally related triggers for allergies?
The AAAAI reports that there is a group of allergy triggers that are closely tied to particular seasons:
• Smoke from summer campfires and winter fireplaces
• Pine trees and wreaths from Thanksgiving to Christmas
• Insect bites and stings
• Chlorine in swimming pools and hot tubs
