Vomiting (known medically as emesis and informally as throwing up and numerous other terms) is the forceful expulsion of the contents of one’s stomach through the mouth and sometimes the nose. Vomiting can be caused by a wide variety of conditions; it may present as a specific response to ailments like gastritis or poisoning, or as a non-specific sequela of disorders ranging from brain tumors and elevated intracranial pressure to overexposure to ionizing radiation.
