Anaphylaxis is serious, potentially life-threatening allergic reaction which is rapid, or sudden, and potentially life-threatening.
One sign of anaphylaxis is shock. Shock has a very specific meaning in medicine: the organs of the body are not getting enough blood because of dangerously low blood pressure. This drop in blood pressure happens when the large blood vessels suddenly expand. If the drop in blood pressure is sudden and drastic, it can lead to unconsciousness, even cardiac arrest and death.
The person in shock may be pale or red, sweaty or dry, confused, anxious, or unconscious.
Breathing may be difficult or noisy, or the person may be unable to breathe.
