A sensation of unease and discomfort in the upper stomach with an urge to vomit.
An attack of nausea is known as a qualm.

The most common cause is gastroenteritis (a stomach infection) or food poisoning but nausea also frequently occurs as a medication side effect and in pregnancy. There are some medications, called antiemetics, that improve symptoms of nausea, including metoclopramide and ondansetron.
