An allergy is an allergic reaction that happens when our immune system decides not to cope with something that is normally harmless to our bodies and decides to overreact by creating antibodies.
The source of the reaction is called an allergen.
Whenever our bodies come into contact with the allergen, they will react and think it is harmful and will then release histamine into our bloodstream in order to fight it.
