Defensive vomiting

Defensive vomiting

Defensive vomiting is a symptom of anorexia nervosa and bulimia nervosa in which a person who has drastically over-eaten (generally in reaction to previous extreme dieting) vomits as a reaction to an excess of food which the body is not prepared to handle. It is often seen in children, shortly after holidays such as Halloween[1] and Easter.

Defensive vomiting can also refer to a tactic used by some animals. Examples include the turkey vulture, which may vomit up foul-smelling semi-digested meat to ward off predators.[2]
