What is defined as anaphylaxis?

Anaphylaxis is defined as a severe allergic reaction that can be life-threatening. This condition typically occurs rapidly after exposure to an allergen and results in a variety of serious symptoms, which can include difficulty breathing, swelling of the throat, a rapid drop in blood pressure, and a widespread rash or hives. The systemic nature of anaphylaxis requires immediate medical attention, often necessitating interventions such as the administration of epinephrine, oxygen, and intravenous fluids. Unlike mild allergic reactions, which may only cause localized symptoms or discomfort, anaphylaxis presents a significant risk to a person's life and demands prompt recognition and treatment to prevent serious complications or death. This distinction is critical in understanding the gravity of anaphylaxis in clinical practice and emergency care.
