Foreign body ingestion
If you swallow a foreign object, it can get stuck in the gastrointestinal (GI) tract from the esophagus (swallowing tube) to the colon (large intestine). This can lead to a blockage or tear in the GI tract.
Children ages 6 months to 3 years are the age group most likely to swallow a foreign object.
These items may include coins, marbles, pins, pencil erasers, buttons, beads, or other small items or foods.
Adults can also swallow foreign objects due to intoxication, mental illness, or dementia. Older adults who have swallowing problems may accidentally swallow their dentures. Construction workers often swallow nails or screws, and tailors and dressmakers often swallow pins or buttons.
Young children like to explore things with their mouths and may swallow an object on purpose or by accident. If the object passes through the food pipe and into the stomach without getting stuck, it will probably pass through the entire GI tract. Sharp, pointed, or caustic objects such as batteries can cause serious problems.
Objects will often pass through the GI tract within a week. In most cases, the object passes through without harming the person.
Sometimes, only minor symptoms are seen at first. The object may be forgotten until symptoms such as inflammation or infection develop.
Any child who is believed to have swallowed a foreign object should be watched for:
Stools (bowel movements) should be checked to see if the object has passed through the body. This will take several days and may sometimes cause rectal or anal bleeding.
A procedure called endoscopy may be needed to confirm if the child has swallowed an object and to remove it. Endoscopy will be done if the object is long or sharp, or is a magnet or disk battery. It will also be done if the child has drooling, breathing difficulty, fever, vomiting, or pain. X-rays may also be done.
In severe cases, surgery may be needed to remove the object.
DO NOT force feed infants who are crying or breathing rapidly. This may cause the baby to inhale liquid or solid food into their airway.
Contact your health care provider, or call 911 or the local emergency number if you think a child has swallowed a foreign object.
