  • Vomiting

    serch.it?q=Vomiting

    Vomiting (synonyms: emesis, puking, barfing, heaving, throwing up, etc.) is the involuntary, forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose. Vomiting can be caused by a wide variety of conditions; it may present as a specific response to ailments like gastritis or poisoning, or as a non-specific sequela of disorders ranging from brain tumors and elevated intracranial pressure to overexposure to ionizing radiation. The feeling that one is about to vomit is called nausea, which often precedes, but does not always lead to, vomiting. Antiemetics are sometimes necessary to suppress nausea and vomiting. In severe cases, where dehydration develops, intravenous fluid may be required. Self-induced vomiting can be a component of an eating disorder, such as bulimia nervosa, and is itself now an eating disorder on its own, purging disorder. Vomiting is different from regurgitation, although the two terms are often used interchangeably. Regurgitation is the return of undigested food back up the esophagus to the mouth, without the force and displeasure associated with vomiting. The causes of vomiting and regurgitation are generally different.

    Cyclic vomiting syndrome (US English) or cyclical vomiting syndrome (UK English) (CVS) is a chronic functional condition of unknown cause characterised by recurring attacks of intense nausea, vomiting, and sometimes abdominal pain, headaches, or migraines. CVS typically develops during childhood, usually between ages 3 and 7; although it often remits during adolescence, it can persist into adult life.

  • Hematemesis

    serch.it?q=Hematemesis

    Hematemesis or haematemesis is the vomiting of blood. The source is generally the upper gastrointestinal tract, typically above the suspensory muscle of duodenum. Patients can easily confuse it with hemoptysis (coughing up blood), although the latter is more common. Hematemesis "is always an important sign".
