Which of these is NOT a symptom of anaphylaxis?

In the context of anaphylaxis, option C, excessive sweating, is not considered a typical symptom. Anaphylaxis is a severe, potentially life-threatening allergic reaction that commonly presents with a constellation of symptoms reflecting systemic involvement, particularly affecting the respiratory and cardiovascular systems. Symptoms often include swelling of the tongue and throat, difficulty breathing, and a dramatic drop in blood pressure, along with skin manifestations like urticaria (hives) and local swelling at the site of exposure.

While sweating can occur with various allergic reactions or responses to stress, it does not directly fit into the profile of anaphylactic symptoms, which are more focused on respiratory distress, cardiovascular instability, and prominent skin reactions. Understanding the specific symptoms of anaphylaxis is crucial for timely recognition and intervention, ensuring those experiencing such a reaction receive immediate medical attention.
