Vomiting is a biological defence mechanism. The major physiological function of vomiting is to remove toxic or harmful substances from the body after ingestion. However, vomiting is multifactorial in origin and can be caused by a range of stimuli, including medical interventions, some of which apparently have little to do with ingesting poisonous substances. In addition to poison ingestion and gastroenteritis, emetic stimuli include motion, surgery, pregnancy, various drugs and radiation. Disgusting sights, smells or memories can also cause nausea and vomiting, and this has a physiological basis leading to avoidance.
