An allergy occurs when your body’s immune system sees a certain substance as harmful. It reacts by causing an allergic reaction. Substances that cause allergic reactions are called allergens. There are many types of allergies. Some allergies are seasonal and others are year-round. Some allergies may be life-long. Common allergies are drug allergies, like being allergic to penicillin, food allergies (nuts, dairy, shellfish, certain fruits and berries), pet allergy (dog or cat fur) and insect allergies (like bee stings). Ex: I want a dog my mom is allergic to them. Ex: When I was younger I was allergic to peanuts.
