| | + | '''Vomiting''' is the forceful upheaval of the contents of the [[stomach]]. Vomiting usually occurs in cases of food poisoning, [[influenza]], early pregnancy, motion sickness, or when someone is inebriated. Vomiting may also be a reaction to [[anesthesia]], caused by the fact that the chemicals used to induce or maintain anesthesia are perceived as toxins by the body's defenses and trigger the same reflexes as if they had been ingested. |
