Coins are usually expelled if eaten into the intestines, but may not be expelled if they are in the esophagus or stomach. After the coin is eaten into the stomach, if it has entered the small intestine and large intestine, and does not lead to obvious damage to the intestinal wall as well as severe abdominal pain, it will generally be discharged with the intestinal peristalsis. However, if the coin is stuck in the esophagus or stomach, the esophagus is relatively narrow and often cannot move downward to discharge. After it reaches the stomach, it may sometimes be discharged into the intestines and excreted in the feces, or it may remain in the stomach for a long time and cannot be discharged. If a coin gets stuck in the esophagus or becomes embedded in the stomach, it often needs to be removed by gastroscopy. If the coin is eaten into the stomach, if it causes obvious discomfort, you should go to the hospital in a timely manner, to clarify the location of the coin and to deal with it.
