What is anaphylactic shock?

Anaphylactic shock is recognized as a severe and life-threatening allergic reaction that can occur rapidly after exposure to an allergen. During this reaction, the immune system overreacts to a substance, leading to a cascade of symptoms that can affect multiple body systems.

In the case of anaphylaxis, common triggers may include foods such as peanuts or shellfish, insect stings, medications, or latex. Symptoms can escalate quickly, presenting as difficulty breathing due to swelling in the throat, a dramatic drop in blood pressure, hives, and gastrointestinal distress, among others. This severe reaction requires immediate medical attention and may necessitate the use of treatments such as epinephrine to reverse the symptoms.

Understanding anaphylaxis is crucial for first responders, as timely intervention can be the difference between life and death. Recognizing this reaction as life-threatening distinguishes it from mild allergic reactions, infections, or routine responses that are not as acute or dangerous.
