What are the signs of anaphylactic shock?

Anaphylactic shock is a severe, potentially life-threatening allergic reaction that occurs rapidly and can lead to significant health dangers if not treated immediately. The signs include difficulty in breathing due to swelling of the airways, especially in the throat, which can obstruct airflow and result in a person feeling suffocated. Additionally, swelling can occur around the face, lips, and tongue, contributing to these breathing difficulties. A rapid drop in blood pressure, known as hypotension, is also a critical sign, as it can lead to shock and organ failure if not addressed promptly.

These symptoms characterize anaphylactic shock effectively, indicating a systemic response to an allergen or irritant. The symptoms associated with dizziness and confusion can occur during episodes of low blood pressure but are not definitive signs of anaphylaxis. Conditions like nausea and vomiting can be supportive of broader allergic reactions but are not the hallmark indicators of anaphylactic shock. Similarly, fever and cough are associated with infections and not with anaphylaxis. Thus, the choice highlighting difficulty breathing, swelling, and a rapid drop in blood pressure accurately reflects the critical signs of anaphylactic shock.
