What are common signs of anaphylaxis?

Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur quickly after exposure to an allergen. Recognizing its signs is crucial for timely intervention. The correct answer highlights some of the most common and critical signs of this condition: difficulty breathing, swelling of the throat, and hives.

When someone experiences anaphylaxis, the body releases a flood of chemicals in response to an allergen, which can cause the airways to constrict and swell, leading to difficulty in breathing. This may also include wheezing or stridor, which are indicative of airway constriction. Swelling of the throat, or angioedema, can further compromise the airway and requires immediate medical attention. Hives, or urticaria, are also a characteristic manifestation, appearing as raised, itchy welts on the skin, indicating an allergic response.

These symptoms are critical to recognize since they can progress rapidly, and the timely administration of epinephrine is essential to mitigate the severe adverse effects of anaphylaxis. Understanding these signs empowers caregivers and bystanders to respond effectively in an emergency situation.
