Three teenagers from Nottingham have ended up in hospital after swallowing small magnets designed to look like tongue piercings.
The girls suffered with abdominal complications, and two of them required major bowel surgery to remove the magnetic parts.
These fake tongue piercings consist of two magnets – one placed on either side of the tongue to hold them in place, to give the impression of a real stud.
Letters have now been sent out to schools across the Midlands to highlight the dangers of swallowing the parts.
The magnets are small enough to not cause a real choking hazard and can pass through the digestive system without complications.
However, if they are swallowed at separate times, the strength of magnetic attraction can cause serious damage to the bowel.
