What is anaphylaxis?

Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur rapidly after exposure to an allergen. The key characteristics of anaphylaxis include the involvement of multiple organ systems, with symptoms such as difficulty breathing, swelling of the throat and tongue, a rapid drop in blood pressure, and hives or skin rash. This type of reaction requires immediate medical attention, often involving the administration of epinephrine to counteract the effects.

In contrast to a minor allergic reaction, which may involve mild discomfort, localized hives, or nasal symptoms, anaphylaxis signifies a serious systemic response. It is more than just chronic allergy symptoms or reactions that are limited to food allergies; it can be triggered by various allergens, including medications, insect stings, and certain foods. Understanding these distinctions is crucial for identifying and responding appropriately to this medical emergency.
