Allergies occur when your body has an exaggerated response to a harmless substance, known as an allergen. Common allergens include pollen, pet dander, dust mites, cockroaches, mold spores, certain foods (including eggs, milk, peanut, soy, wheat, shellfish, and tree nut), latex rubber, poison ivy, and insect stings.
