Who are at risk for foreign body ingestion?
Eighty percent of foreign-body ingestions occur in children, whereas almost all foreign bodies inserted into the rectum are described in adults.
Groups at increased risk for foreign-body ingestion include psychiatric patients, prisoners, and those who frequently and excessively use alcohol or sedative-hypnotic medications. Also at risk are older adult subjects, who may have poorly fitting dentures, impaired cognitive function resulting from medications, or dementia or dysphagia after stroke.
Intentional ingestion of foreign objects is well described in smugglers of illicit drugs, jewelry, or other valuable items.
