Allergy Allergie
Allergy is the immune system's reaction to unfamiliar substances, such as: pollen grains, venom from a bee sting or animal dander.
The immune system produces proteins called antibodies that protect the body from unwanted foreign bodies that may invade the body and cause disease or infection. When someone is allergic to a particular substance, their immune system produces antibodies that identify the allergen and treat it as a harmful agent, although It is not, which leads to the release of histamine and other substances that cause allergy symptoms.
Allergies may cause different symptoms, as they can appear on the skin, in the sinuses, in the respiratory airways, or in the digestive system, as the severity and degree of severity of allergies varies from one person to another, as it can cause anaphylactic shock, an emergency that may It causes death, and allergies cannot be completely cured, but there are some treatments that help relieve allergy symptoms .
