The effects of eating wire in the stomach are related to the size of the wire. If the wire is very short and small, the symptoms may not be obvious; if the wire is longer and larger, abdominal pain, nausea, vomiting blood and other symptoms will occur. 1. If the length of the wire that the patient eats into the body is very short and small, the damage to the mucosa of the esophagus and gastrointestinal tract is relatively mild, which generally does not cause obvious symptoms, but may also cause stomach discomfort, nausea, vomiting and other symptoms. 2. If the wire is long and large, the patient will damage the esophagus and gastrointestinal mucosa if ingested accidentally, and the patient will experience gastrointestinal symptoms such as nausea, vomiting and abdominal pain. In addition, if the wire is embedded in the intestines, it may perforate the gastrointestinal tract with the peristalsis of the gastrointestinal tract, resulting in severe abdominal pain, vomiting blood, black stool and other symptoms. It is recommended that patients who accidentally ingested iron wire, go to the hospital in a timely manner, so as not to delay their condition.
