What happens when your child swallows a coin? Doctors typically turn to endoscopy—a procedure using a camera to retrieve the object—which requires anesthesia and hospital admission. But new research from Frontiers in Pediatrics describes a case where olive oil offered a gentler alternative.
Researchers treated a 6-year-old boy who swallowed a coin four hours before arriving at hospital. An X-ray showed the coin was stuck in his lower esophagus (the tube from mouth to stomach). The boy had drooling and chest pain.
Olive oil helped the coin move naturally
Instead of scheduling endoscopy immediately, doctors gave the boy olive oil at 1 millilitre per kilogram of body weight, followed by unlimited water. One hour later, a follow-up X-ray showed the coin had moved into the intestines. Within 24 hours, the coin passed naturally in stool, and the boy went home without problems.
The researchers think olive oil works by lubricating both the coin and esophageal walls, allowing the coin to slip through more easily. However, this is a single case study, so the evidence is limited to this one example.
Success depends on timing and location
This approach will not work for all coin ingestions. It works only when the coin is in the lower esophagus (not higher up), and ideally within a few hours of swallowing. The child must show no signs of serious complications like inability to swallow saliva or breathing difficulty. Your doctor must assess your child carefully and confirm the coin's location with an X-ray before attempting this method.
In Singapore, foreign body ingestion is one of the most common reasons children visit emergency departments, with coins being the most frequent object. If this approach proves effective across more cases, it could reduce unnecessary hospital admissions and spare children exposure to anesthesia.
Steps to take if your child swallows a coin
- Seek medical evaluation immediately and request an X-ray to locate the coin precisely.
- Ask your doctor whether olive oil followed by water is appropriate based on where the coin is located and how long ago it was swallowed.
- Follow your doctor's guidance—endoscopy may still be necessary depending on your child's specific situation.
