Which of the following is NOT a symptom of anaphylaxis?

Loss of appetite is not considered a symptom of anaphylaxis. Anaphylaxis is a severe and potentially life-threatening allergic reaction characterized by the abrupt onset of symptoms that affect multiple organ systems. Common symptoms include hypotension, which refers to a significant drop in blood pressure; itching, often resulting from skin reactions or urticaria (hives); and swelling of the tongue or throat, which can lead to breathing difficulties and is a hallmark of this acute reaction.

Loss of appetite may occur as a secondary effect due to discomfort or illness, but it is not a direct symptom of anaphylaxis. Understanding the primary symptoms of anaphylaxis is critical for recognizing and responding promptly to this medical emergency.
