Definition: An "atopic allergy" is a type of allergic reaction that happens quickly (usually within minutes) in a person who is sensitive to certain allergens (substances that can cause an allergic reaction). This means if someone has an atopic allergy, their body reacts strongly when they come into contact with something they are allergic to.
In summary, an "atopic allergy" is a quick allergic reaction in sensitive individuals. It’s important to understand this term, especially if you or someone you know has allergies.
