<h3>What is adverse response or an allergic response?</h3>
An aberrant immunological reaction is an allergy. The purpose of the human immune system is to defend against external threats, and in individuals with allergies, the immune system will react to allergens (substances that trigger an immune response).
Immune cells will make immunoglobulin E, or IgE, antibodies in response to each allergen. Histamine will be produced by body cells as a result of the antibodies. In order to cause symptoms of an allergic reaction, this histamine will operate on many bodily parts, including the eyes, throat, nose, gastrointestinal tract, skin, or lungs.
The allergic reaction is not constrained to a specific level of exposure. The immune system will respond each time the allergen is present if the body is repeatedly exposed to it.
