What does "anaphylaxis" refer to?

Anaphylaxis refers to a sudden, severe allergic reaction that can be life-threatening. It is a rapid onset condition that can occur after exposure to an allergen such as certain foods, insect stings, medications, or latex. The body's immune response in anaphylaxis involves the release of chemicals like histamine, leading to symptoms such as difficulty breathing, swelling of the throat and tongue, a drop in blood pressure, and hives. This serious reaction requires immediate medical attention, typically in the form of an epinephrine injection, to counteract the severe symptoms and prevent complications. Understanding anaphylaxis is crucial for flight attendants, as they may encounter situations involving passengers with known allergies, necessitating quick identification and response to any allergic emergencies.
