Common Allergens

Common allergens are substances that can trigger immune reactions in some people. These include foods like peanuts, tree nuts, milk, eggs, shellfish, and wheat; environmental triggers such as pollen, dust mites, mold, and pet dander; insect stings; and certain medications. When sensitive individuals are exposed, their immune system mistakenly identifies these harmless substances as threats, leading to reactions that can range from mild symptoms like sneezing or skin rashes to severe reactions like difficulty breathing or anaphylaxis. Recognizing these common allergens is key to managing allergies and avoiding adverse health effects.
