What are Allergies? (HealthSketch)

Allergies affect many people worldwide, occurring when the immune system reacts to harmless substances called allergens. Common allergens include pollen, foods, insect stings, and more. The immune response involves IGE antibodies and mast cells, leading to symptoms like rashes, sneezing, and in severe cases, anaphylaxis. Diagnosis involves history, family background, and tests. Management includes avoiding allergens, medications, and possibly immunotherapy. Awareness and preparation are key to managing allergies effectively.
