An allergy is when your immune system reacts to something that’s normally harmless to most people. If you come into contact with a substance that your immune system views as a threat, called an allergen, it responds by releasing a chemical called histamine and other substances. The release of these substances is what causes your allergic reaction. Atopy, or having an atopic predisposition, refers to the genetic predisposition to develop allergic diseases.
