Vomiting

Expulsion of stomach contents via the mouth or nose

Vomiting (scientifically known as emesis, and otherwise known as puking, and throwing up) is the forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose. The vomited contents are known as vomit or vomitus. Vomiting can be the result of ailments such as food poisoning, gastroenteritis, pregnancy, motion sickness, or hangover; or it can be an after effect of diseases such as brain tumors, elevated intracranial pressure, or overexposure to ionizing radiation.
