Allergies are a type of immune response in which the body's defense mechanisms react abnormally to typically harmless substances, known as allergens. These reactions can cause a variety of symptoms, ranging from mild to severe. Allergies can be categorized into several types based on the part of the body affected and the type of allergen involved.

Food allergies occur when the immune system reacts to certain proteins found in food. Common food allergens include peanuts, milk, eggs, wheat, soy, and fish. Symptoms can range from mild, such as hives or itching, to severe, including anaphylaxis, a life-threatening condition that requires immediate medical attention.

Insect sting allergies involve reactions to the venom of bees, wasps, or ants. Symptoms can include redness, swelling, itching, and in severe cases, anaphylaxis.

Environmental allergies, also known as atopic allergies, occur when the immune system reacts to substances found in the environment, such as pollen, dust mites, or mold. Symptoms can include sneezing, itching, watery eyes, and in severe cases, asthma attacks.

Medications can also cause allergic reactions in some individuals. These reactions can range from mild, such as rash or itching, to severe, including anaphylaxis.

Allergies are typically treated with medications, such as antihistamines, decongestants, or corticosteroids, and in severe cases, with epinephrine for anaphylaxis. In some cases, allergy shots or immunotherapy may be used to desensitize the immune system to specific allergens.
