Hymenoptera venom allergy

Hymenoptera venom allergy occurs when the immune system overreacts to venom from stinging insects like bees, wasps, or hornets. For some people, a sting triggers a severe allergic response, which can include swelling, hives, difficulty breathing, or even anaphylaxis—a life-threatening reaction. This allergy is caused by the body seeing the venom as a dangerous substance and releasing chemicals to fight it. Diagnosis often involves allergy testing, and treatment may include carrying epinephrine auto-injectors and undergoing allergy immunotherapy to reduce the risk of future severe reactions.
