What are the causes of allergy?

A weakened immune system causes allergies to any foreign molecules in the environment. Common allergens include: pollen, food allergies, insect stings, nuts, dust, and medications are common causes of severe reactions. Allergies are the result of a natural immune to a typically harmful substance. Ige, or immunoglobulin, is freed to destroy the allergen and to diminish the production of chemicals that trigger an allergic reaction.

One of these chemicals is called histamine. Histamines cause the strengthening of the muscles in the airways and walls of blood vessels. It also instructs the lining of the nose to create more mucous. A particular antibody called immunoglobin directly causes allergic reactions. These antibodies are released to fight potentially harmful substances.

Allergies occur as a result of your body’s immune response to certain substances. The substances that trigger your immune system are called allergens. Examples of allergens are divided into the following categories:

Airborne allergies: dust mites, animal dander, fur, shellfish, and pollen Foods: peanuts, wheat, tree nuts, eggs, milk, soy.

Medications: penicillin, sulphonamides, and salicylates Metals: nickel, zinc, cobalt, and chromium. Insect bites/stings: horseflies, wasps, bee, kissing bugs, and blackflies Latex.

These allergens trigger the release of antibodies known as immunoglobin E (IgE), which fights the harmless substances. IgE causes the production and release of chemicals that cause the allergic reaction.
