Vomiting (known medically as emesis and informally as throwing up and numerous other terms) is the involuntary, 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. The feeling that one is about to vomit is called nausea, which often precedes, but does not always lead to, vomiting. Antiemetics are sometimes necessary to suppress nausea and vomiting. In severe cases, where dehydration develops, intravenous fluid may be required.
Vomiting is different from regurgitation, although the two terms are often used interchangeably. Regurgitation is the return of undigested food back up the esophagus to the mouth, without the force and displeasure associated with vomiting. The causes of vomiting and regurgitation are generally different.
Encounters[]
Timothy Mok had made their encounter in Primary 3 at certain times, the last time it happened was in 2002. Mostly it was done at the IMM Building. Timothy Mok had made their encounter when in Primary 5 at the Ashford Walkway Tunnel (2008). He was able to successfully use the Patronus Charm and was subsequently rescued by a Squib named Arabella Figg. Harry was put on trial for his use of Underage magic, but ultimately not punished, as it was recognised as having been self-defence. Nearly a year later Ms Huda revealed what she had done to Timothy.
