Foreign body ingestion occurs when a child accidentally swallows an object that is not meant to be eaten. It is most common in babies, toddlers and young children because they often explore objects by putting them in their mouths.
Coins are the most commonly swallowed objects in children. Small toy parts, jewellery, button batteries, magnets, screws, pins and bones may also be swallowed.
Some smooth objects may pass through the digestive system without causing harm. However, button batteries, magnets and sharp objects can cause serious internal injury and require immediate medical attention.
Symptoms may include drooling, difficulty swallowing, vomiting, coughing, abdominal pain or breathing problems. Parents should not induce vomiting or give food to push the object down. Early medical evaluation can help prevent serious complications.
What Objects Do Children Commonly Swallow?
Children may swallow small household objects while playing or exploring their surroundings. The risk depends on the object’s size, shape, material and location inside the body.
Coins
Coins are among the most frequently swallowed foreign objects in children. A coin may pass into the stomach or become stuck in the food pipe.
A child with a coin stuck in the food pipe may experience:
Drooling
Difficulty swallowing
Vomiting
Chest discomfort
Refusal to eat
Medical evaluation and an X-ray may be required to identify the coin’s location.
Small Toys and Toy Parts
Small toy parts, beads, building-block pieces, toy wheels and other small items can be swallowed easily.
Some smooth objects may pass naturally after entering the stomach. However, parents should not assume that every object will pass safely without medical assessment.
Jewellery and Household Objects
Children may swallow rings, earrings, pendants, screws, pins and other small household items.
The risk depends on whether the object is smooth, sharp, pointed or large enough to become stuck in the digestive tract.
Button Batteries
Button batteries are small, round batteries found in:
Watches
Remote controls
Toys
Calculators
Hearing aids
Electronic devices
A button battery can cause severe tissue damage when it becomes stuck in the food pipe. Injury may begin even when the child does not initially show symptoms.
Suspected button battery ingestion requires immediate emergency care. Do not wait for symptoms to appear.
Magnets
Swallowing one magnet can be dangerous, but swallowing two or more magnets is especially serious.
Magnets in different parts of the intestine may attract each other through the intestinal walls. This can cause:
Tissue damage
Intestinal blockage
Perforation
Infection
Seek urgent medical care when magnet ingestion is suspected, even if the child appears comfortable.
Sharp or Pointed Objects
Sharp objects may include:
Pins
Needles
Screws
Nails
Safety pins
Broken plastic
Pieces of glass
These objects can injure the throat, food pipe, stomach or intestine. Sharp-object ingestion requires prompt medical evaluation.
Do not wait at home for the object to pass.
Bones and Food-Related Objects
Fish bones, chicken bones and hard pieces of food may become stuck in the throat or food pipe.
The child may experience:
Pain while swallowing
Coughing
Drooling
Refusal to eat
A feeling that something is stuck
Do not give bread, rice, bananas or other food to push the object down.
What Are the Symptoms of Foreign Body Ingestion?
Some children may have no immediate symptoms, particularly when the object has passed into the stomach.
Other children may develop:
Sudden coughing or choking
Drooling
Difficulty or pain while swallowing
Refusal to eat or drink
Vomiting
Chest or neck pain
Abdominal pain
Noisy breathing
Breathing difficulty
Blood in saliva, vomit or stool
Abdominal swelling
Fever
Unusual irritability in babies
Symptoms depend on the type of object and whether it is located in the airway, food pipe, stomach or intestine.
When Is Foreign Body Ingestion an Emergency?
Take the child to an emergency department immediately when:
A button battery may have been swallowed
One or more magnets may have been swallowed
The object is sharp or pointed
The object is large or long
The child has difficulty breathing
The child cannot swallow saliva
There is continuous drooling
The child has repeated vomiting
There is severe chest, throat or abdominal pain
Blood appears in the saliva, vomit or stool
The abdomen becomes swollen or painful
The child becomes unusually sleepy or unwell
The swallowed object is unknown
A child who cannot breathe, speak, cry or cough effectively may have an object blocking the airway and requires immediate emergency assistance.
What Should Parents Do After a Child Swallows an Object?
Remain calm and remove any other small objects from the child’s reach.
Try to identify:
What the child swallowed
How many objects may be missing
When the incident occurred
Whether the child has symptoms
Bring an identical object, its packaging or a photograph to the hospital when possible. This may help the medical team understand its size, shape and material.
Parents should not:
Induce vomiting
Put fingers blindly into the child’s mouth
Give food to push the object down
Give laxatives or digestive medicines
Wait at home after suspected battery, magnet or sharp-object ingestion
Do not give food or drinks until a medical professional advises that it is safe. The child may require imaging, sedation or an urgent procedure.
How Is a Swallowed Foreign Object Diagnosed?
The doctor will ask what the child swallowed, when it happened and whether symptoms are present.
The child’s mouth, throat, breathing and abdomen may be examined.
An X-ray may be used to locate:
Coins
Button batteries
Magnets
Screws
Other metallic objects
Some materials, including certain plastics, wood and thin bones, may not appear clearly on an X-ray. Additional imaging or endoscopic examination may therefore be required.
How Is Foreign Body Ingestion Treated?
Treatment depends on:
The type of object
Its size and shape
Its location
How long ago it was swallowed
The child’s age
Whether symptoms are present
A small, smooth object that has entered the stomach may sometimes be monitored under medical guidance.
The doctor may advise parents about symptoms to watch for and whether follow-up imaging is needed.
Urgent endoscopic removal may be required when:
An object is stuck in the food pipe
A button battery has been swallowed
Multiple magnets have been swallowed
The object is sharp or pointed
The child has significant symptoms
Surgery is less commonly required but may be necessary if the object causes intestinal blockage, perforation or another serious complication.
Pediatric Gastroenterology Guidance for Swallowed Objects
Foreign body ingestion cannot be managed only according to whether the child currently looks comfortable. The object’s type, size and location are important because some high-risk objects can cause internal injury before clear symptoms appear.
Dr. Nidhi Saini, DNB, PDCC in Pediatric Gastroenterology, has specialist training in gastrointestinal conditions affecting infants, children and adolescents.
She completed fellowship training in Pediatric Gastroenterology at SGPGI, Lucknow, followed by two years of Senior Residency in the same department.
For children with suspected foreign body ingestion, specialist evaluation can help determine whether observation is appropriate or whether imaging, hospital referral or endoscopic removal is required.
How Can Parents Prevent Foreign Body Ingestion?
Keep coins, batteries, magnets, jewellery, screws and small toy parts locked away and out of children’s reach.
Parents should also:
Check toys regularly for loose parts
Follow age recommendations on toy packaging
Secure battery compartments with screws
Avoid toys containing loose, powerful magnets
Keep jewellery and small household objects in closed storage
Supervise young children while eating
Check food carefully for bones
Has Your Child Swallowed a Foreign Object?
Do not wait for symptoms when a child may have swallowed a button battery, magnet, sharp object or an unknown item.
Early medical evaluation can identify the object’s location and help prevent serious complications.
Frequently Asked Questions
What is the most common foreign body swallowed by children?
Coins are among the most commonly swallowed foreign objects. However, button batteries, magnets and sharp objects carry a greater risk of serious injury.
What should I do if my child swallows a coin?
Seek medical advice to determine whether an X-ray is required. Get urgent help if the child has drooling, difficulty swallowing, vomiting, breathing problems, chest pain or abdominal pain.
Can a swallowed coin pass naturally?
Some coins may pass naturally after entering the stomach. However, a coin can become stuck in the food pipe, so its location should be confirmed when advised by a doctor.
What happens if a child swallows a button battery?
A button battery can cause severe tissue injury when stuck in the food pipe. Suspected button battery ingestion is an emergency, even if the child has no symptoms.
Why are swallowed magnets dangerous?
Two or more magnets can attract each other through different sections of the intestine. This can cause pressure injury, intestinal blockage or perforation.
How do I know whether something is stuck in my child’s throat?
Warning signs include drooling, difficulty swallowing, refusal to eat, repeated vomiting, coughing, noisy breathing and neck or chest pain.
Should I make my child vomit after swallowing an object?
No. Do not induce vomiting because the object may cause further injury or enter the airway while coming back up.
Can I give my child food to push the object down?
No. Do not give bread, rice, bananas or other foods to push the object down. This may worsen the injury or delay necessary treatment.
Does every swallowed object require endoscopy?
No. Treatment depends on the object, its location and the child’s symptoms. Some smooth objects can be monitored, while batteries, magnets, sharp objects and objects stuck in the food pipe may require urgent removal.
When should I consult a pediatric gastroenterologist?
A pediatric gastroenterologist may be involved when an object is lodged in the digestive tract, requires endoscopic removal or needs specialist follow-up. High-risk or symptomatic ingestion requires immediate emergency assessment.
