Anaphylaxis is a severe, rapid-onset allergic reaction that can affect the whole body and is potentially life-threatening. It occurs when the immune system releases a flood of chemicals in response to an allergen, which can cause the airway to narrow, blood pressure to drop suddenly, and hives or swelling to develop, among other symptoms. Common triggers include certain foods, insect stings, and medications, and prompt treatment with epinephrine is required to prevent death.
