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.
