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.

Defensive vomiting can also refer to a tactic used by some animals. In the presence of a threat, they vomit towards the threat, thus possibly distracting a predator and perhaps obscuring their scent.
