Common allergies are typically split up into two main categories – food allergies, and airborne allergies. Food allergies are those triggered by the ingestion of certain foods. These allergies are often caused by proteins in the food, and can cause symptoms such as hives, swelling, difficulty breathing, and even anaphylactic shock. Common food allergies include peanuts, tree nuts, eggs, wheat, soy, fish, and shellfish. Treatment for food allergies typically involves avoiding the allergen and carrying epinephrine in case of an emergency. Airborne allergies are typically triggered by exposure to certain substances in the air, including pollens, mold, and pet dander. Symptoms of airborne allergies can include coughing, sneezing, itchy eyes, and nasal congestion. Treatment for these allergies will vary based on the cause, but can include avoiding exposure to the allergen, using over-the-counter antihistamines, and seeing an allergist for further management.

Common allergies include hay fever, food allergies, and allergic reactions to medications or insect stings. Treatment may involve avoiding the allergen, taking medication such as antihistamines or nasal sprays, or in severe cases, carrying an epinephrine auto-injector. Working with a healthcare professional to identify the specific allergen and develop a management plan is important.
