Anaphylactic shock is among the extreme cases and danger situations that occur with immediate hypersensitivity reactions, and it is marked by the quick appearance of systemic symptoms that involve multiple organ systems. The present study explores the causative agents of anaphylaxis, discusses the early clinical manifestations that are critical for prompt treatment, and classifies the different types according to the mechanisms of triggering and the manner in which they affect the body.
