What is a common symptom of anaphylaxis?

Rapid swelling of the face and throat is a hallmark symptom of anaphylaxis. This condition is a severe, potentially life-threatening allergic reaction that can occur quickly after exposure to an allergen, such as certain foods, medications, or insect stings. The swelling, known as angioedema, can obstruct the airways and lead to respiratory distress, making it crucial for emergency responders to recognize this symptom promptly. Other typical signs of anaphylaxis can include hives, wheezing, difficulty breathing, or a rapid drop in blood pressure, but the rapid swelling of the face and throat stands out due to its immediate and serious implications for airway safety.
