vomiting

v. eject stomach contents through the mouth; throw up

Emesis redirects here. For the genus of metalmark butterflies, see Emesis (butterfly). Heaving redirects here. For the up-and-down motion, see heave.Vomiting (also called throwing up or emesis) is the forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose. Vomiting may result from many causes, ranging from gastritis or poisoning to brain tumors, or elevated intracranial pressure (ICP). The feeling that one is about to vomit is called nausea. It usually precedes, but does not always lead to vomiting. Antiemetics are sometimes necessary to suppress nausea and vomiting, and in severe cases where dehydration develops, intravenous fluid may need to be administered to replace fluid volume. The medical branch investigating vomiting, emetics and antiemetics is called emetology.
