how is it classified?
There are three main classifications of anaphylaxis: Anaphylactic, Biphasic anaphylaxis, and Pseudoanaphylaxis or anaphylactoid.
Anaphylaxis
There are three main classifications of anaphylaxis. Anaphylactic shock is associated with systemic vasodilation that causes low blood pressure which is by definition 30% lower than the person's baseline or below standard values. Biphasic anaphylaxis is the recurrence of symptoms within 1–72 hours with no further exposure to the allergen. Reports of incidence vary, with some studies claiming as many as 20% of cases. The recurrence typically occurs within 8 hours. It is managed in the same manner as anaphylaxis. Pseudoanaphylaxis or anaphylactoid reactions are a type of anaphylaxis that does not involve an allergic reaction but is due to direct mast cell degranulation. Non-immune anaphylaxis is the current term used by the World Allergy Organization with some recommending that the old terminology no longer be used.
true or false anaphylaxis generally only affects the skin and eyes False what all does it affect? Skin,  respiratory, gastrointestinal, heart and vasculature, and central nervous system. what is anaphylaxis? It is a serious allergic reaction that is rapid in onset and may cause death. what are some of its signs? Itchy rash, throat or tongue swelling, shortness of breath, vomiting, lightheadedness, low blood pressure, and temporary blindness. what are some of its symptoms? Itchy rash, throat or tongue swelling, shortness of breath, vomiting, lightheadedness, low blood pressure, and temporary blindness. what are its causes? Common triggers include venom from insect bites or stings, foods, and medication. what are its risk factors? People with atopic diseases such as asthma, eczema, or allergic rhinitis are at high risk of anaphylaxis from food, latex, and radiocontrast agents but not from injectable medications or stings. how is it diagnosed? During an attack, blood tests for tryptase or histamine (released from mast cells) might be useful in diagnosing anaphylaxis due to insect stings or medications. are there any other kinds of diagnosis? Skin involvement may include: hives, itchiness or a swollen tongue among others. Respiratory difficulties may include: shortness of breath, stridor, or low oxygen levels among others.
