Under normal circumstances, coins can be discharged by themselves with gastrointestinal peristalsis, but if the coin mistakenly enters the respiratory tract or becomes embedded in the intestinal wall, it usually cannot be discharged by itself. If a coin is swallowed, it is important to go to a regular hospital in time for a radiographic examination to clarify the location of the coin. Usually, if the accidentally swallowed coin has entered the stomach smoothly, and no intestinal embedded, with the gastrointestinal peristalsis, one or two days with the feces can be discharged from the body. However, if the coin mistakenly entered the respiratory tract, or the coin in the intestinal tract has become embedded, resulting in intestinal obstruction, in this case, the coin can not be discharged on its own, and you need to go to the hospital in a timely manner, through the endoscopy and other means to remove. In conclusion, if the coin is not swallowed into the respiratory tract and does not become embedded, it can usually be discharged on its own, and it is recommended to go to the hospital in time for a radiological examination.
