Experiencing life-threatening breathing or circulation problems is a key sign of anaphylaxis. Anaphylaxis is a severe allergic reaction that can occur rapidly and affect multiple systems in the body. This condition often leads to difficulty breathing due to swelling of the airway and a drop in blood pressure, which can result in shock. Symptoms like wheezing, shortness of breath, and a rapid or weak pulse indicate that the person's ability to breathe and circulate blood effectively is compromised, which is characteristic of anaphylactic reactions.

Other signs of anaphylaxis can include hives, swelling of the face or throat, abdominal pain, and gastrointestinal symptoms, but the critical concern lies in the immediate risk to the airway and circulation. This urgency is what differentiates anaphylaxis from less severe allergic reactions and highlights the necessity for prompt medical intervention.
