Small objects are commonly swallowed by children but can be accidently swallowed by anyone.
Most small objects that have been swallowed will enter the digestive system and leave the body naturally without causing harm but medical advice should be sought regardless as some items can cause blockages or perforations within the body.
Batteries or magnets have the potential for complications and the casualty should seek urgent medical attention.
If the object becomes stuck in the respiratory tract choking procedures should be followed and emergency medical assistance called.
Should sharp or larger items be swallowed, such as nails, fish bones or glass you must seek urgent medical attention.
