Whether or not a toddler can pull a long magnet out of his or her body depends on the specific situation; if the magnet is small, he or she may be able to pull it out, and if the magnet is large, he or she may not be able to pull it out. If a toddler ingests a small magnet with smooth edges, it may be able to be expelled from the body after one to three days. However, if the magnet ingested by a toddler is large or long, it will not be easy to be discharged and may cause intestinal obstruction, etc. In this case, the guardian should pay more attention to the situation, and if the toddler is in discomfort or constipation, X-ray examination should be carried out in a timely manner to clarify the situation of the foreign body and to remove the foreign body. If the magnet is not smooth, it may cause damage to the gastrointestinal tract of the toddler. If the toddler suffers from abdominal discomfort, intestinal obstruction, vomiting blood, or blood in stool, he should seek medical attention to stop the bleeding and remove the foreign body. Young children should go to the hospital in a timely manner after accidentally eating a long magnet, and the doctor should choose the appropriate treatment measures according to the condition to avoid adverse consequences.
