What are some common signs and symptoms of anaphylaxis?

Anaphylaxis is a severe and potentially life-threatening allergic reaction that typically manifests rapidly following exposure to an allergen. Common signs and symptoms associated with this condition include nausea, vomiting, stridor (a high-pitched wheezing sound resulting from obstructed airflow), and rash.

Nausea and vomiting can occur due to gastrointestinal involvement or as part of the body's generalized response to a severe allergic reaction. Stridor indicates significant respiratory distress, which is a hallmark of anaphylaxis, as the airway may be compromised through swelling of the larynx and surrounding tissues. The rash, often urticarial in nature, can represent skin involvement in the reaction, indicating systemic effects of the allergen.

Recognizing these symptoms is critical, as anaphylaxis can escalate quickly and requires immediate medical intervention, often through the administration of epinephrine. Understanding these common signs and symptoms helps responders identify and appropriately manage anaphylactic situations effectively.
