What is anaphylaxis Google Scholar?
“Anaphylaxis is a serious systemic hypersensitivity reaction that is usually rapid in onset and may cause death. Severe anaphylaxis is characterized by potentially life-threatening compromise in airway, breathing and/or the circulation, and may occur without typical skin features or circulatory shock being present.”
What is the difference between anaphylactic shock and anaphylaxis?
The terms “anaphylaxis” and “anaphylactic shock” are often used to mean the same thing. They both refer to a severe allergic reaction. Shock is when your blood pressure drops so low that your cells (and organs) don’t get enough oxygen. Anaphylactic shock is shock that’s caused by anaphylaxis.
What is the difference between allergic reaction and anaphylaxis?
In most cases, people with allergies develop mild to moderate symptoms, such as watery eyes, a runny nose or a rash. But sometimes, exposure to an allergen can cause a life-threatening allergic reaction known as anaphylaxis . This severe reaction happens when an over-release of chemicals puts the person into shock.
What are two signs of anaphylaxis?
The symptoms include:
- feeling lightheaded or faint.
- breathing difficulties – such as fast, shallow breathing.

Classification. The term anaphylaxis is often reserved to describe immunological, especially IgE-mediated reactions. A second term, non-allergic anaphylaxis, describes clinically identical reactions that are not immunologically mediated. The clinical diagnosis and management are, however, identical.
What are common causes of anaphylaxis?
Anaphylaxis (an-a-fi-LAK-sis) is a serious, life-threatening allergic reaction. The most common anaphylactic reactions are to foods, insect stings, medications and latex. If you are allergic to a substance, your immune system overreacts to this allergen by releasing chemicals that cause allergy symptoms.
