forcible expulsion of the contents of the stomach through the mouth From Wikipedia, the free encyclopedia
Vomiting, also called puking or emesis, is emptying the contents of stomach through mouth. It can be either food or liquid in the stomach. It can be from infection, contaminated food or drink (food poisoning), foul smells or foul-tasting food, the brain being injured, a block in the small intestines so food and liquid cannot go through, too much alcohol or other drugs. Also, people can make themselves vomit (self-induced) which is called purging. Usually, people who have eaten or drunk poison are made to vomit any residual (leftover) poison. Excessive vomiting may lead to dehydration, which can be dangerous, if not fatal as it will shut down a person's organs and twist the intestines.
