What to do if 4 years old child swallow magnet(foreign body ingestion). xray shows that its in small bowl loops?

This depends. If you are sure it is only one, it will eventually pass out of the poop in a week or less. X-rays can document movement/elimination. If you are not absolutely sure it was just one, it may need removal. If there are 2 high strength magnets at different intestine levels they can draw together & kill compressed bowel tissue by compromising blood flow= emergency abdominal surgery.

Hope it will pass. Local Drs who have seen x ray best to consult on this. Keep him way from iron skillets. ;-) Dr humor. Size would and shape would be important.

baby will poop it out
