Anaphylaxis is defined as a severe and potentially life-threatening allergic reaction that can occur in response to certain food allergens, among other triggers. This kind of reaction typically involves multiple systems within the body, leading to symptoms such as difficulty breathing, swelling of the throat, a rapid drop in blood pressure, and skin reactions like hives or flushing. It can occur quickly after exposure to the allergen, often within minutes, and requires immediate medical attention.

Understanding this condition is crucial for clinical nutritionists, as they often work with clients who may have known food allergies. Recognizing the severity of anaphylaxis differentiates it from milder allergic reactions, which may cause symptoms like itching or mild rashes but do not pose an immediate threat to life. This knowledge is important for providing accurate dietary advice and emergency response plans for those at risk of anaphylaxis.
