Allergies occur when the body’s immune system reacts abnormally to foreign substances that are usually harmless. A brief YouTube video titled “Allergy – Mechanism, Symptoms, Risk Factors, Diagnosis, Treatment and Prevention, Animation” covers everything you need to know about allergy, symptoms, and treatment.

The environment, food, latex products, and medication are all examples of common allergens. Examples of airborne contaminants include pet dander, pollen, pollen grains, and house dust.

Allergens can also be found in dairy products, eggs, shellfish, and even tree nuts. As a result, antibiotics can also develop into genuine allergies.

Gloves, bandages, and other medical tools and products are examples of latex products.

Immunoglobulin E (IgE) is the primary receptor for most allergens in the body. When an allergen is introduced into the body for the first time and activated by TH2, it is produced. On a mast cell, IgE molecules now covalently link. When the same allergens are reintroduced, the body responds by releasing histamine.

This results in a mild to severe fever, depending on the extent of the exposure. Certain allergies are hereditary, while others develop into mutant forms. Diagnosis may facilitate the pursuit of allergy treatment.
