Vomiting
forcible expulsion of the contents of the stomach through the mouth
Vomiting (scientifically known as emesis, and otherwise known as puking, and throwing up) is the forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose. The vomited contents are known as vomit or vomitus.
Vomiting can be the result of ailments such as food poisoning, gastroenteritis, pregnancy, motion sickness, or hangover; or it can be an after effect of diseases such as brain tumors, elevated intracranial pressure, or overexposure to ionizing radiation. The feeling that one is about to vomit is called nausea; it often precedes, but does not always lead to vomiting. Impairment due to alcohol, anesthesia, or other sedatives can cause inhalation of vomit. In severe cases, where dehydration develops, intravenous fluid may be required. Antiemetics are sometimes necessary to suppress nausea and vomiting. Self-induced vomiting can be a component of an eating disorder such as bulimia nervosa, and is itself now classified as an eating disorder on its own, purging disorder.
Complications
Aspiration
Vomiting is dangerous if gastric content enters the respiratory tract. Under normal circumstances, the gag reflex and coughing prevent this from occurring; however, these protective reflexes are compromised in persons who are under the influence of certain substances (including alcohol) or even mildly anesthetized.

Why this record matters
“Vomiting” is worth following because a concise public description often conceals a longer documentary argument. Here, Vomiting, forcible and expulsion provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q127076. The Library of Congress control number is sh85144382. None of the 1 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
