What is anaphylaxis?

Anaphylaxis is defined as a severe allergic reaction that can be life-threatening. This condition occurs when the immune system reacts aggressively to an allergen, which may include foods, insect stings, medications, or other triggers. During anaphylaxis, the body releases a flood of chemicals, which leads to symptoms such as difficulty breathing, swelling of the throat, a rapid drop in blood pressure, and potentially fatal complications if not treated promptly.

Recognizing anaphylaxis is crucial because it requires immediate medical attention and intervention, typically with an epinephrine injection. This differentiates it from milder allergic reactions, which may cause discomfort but are not immediately life-threatening. Understanding the seriousness of anaphylaxis is essential for effective first aid response and ensuring the safety of those who are at risk.
