The symptoms that might arise because of battery ingestion:
No obvious symptoms
Unfortunately, it is not obvious when a button or coin battery is stuck in
a child's oesophagus (food pipe).
There are no specific symptoms associated with this. The child might:
cough, gag or drool a lot;
appear to have a stomach upset or a virus;
be sick;
point to their throat or stomach;
have a pain in their abdomen, chest or throat;
be tired or lethargic;
be quieter or more clingy than usual or otherwise "not themselves";
lose their appetite or have a reduced appetite; and
not want to eat solid food / be unable to eat solid food.
These sorts of symptoms vary or fluctuate, with the pain increasing and
then subsiding.
A specific symptom to button and coin battery ingestion is vomiting
fresh (bright red) blood. If the child does this seek immediate medical
help.
The lack of clear symptoms is why it is important to be vigilant with
"flat" or spare button or coin batteries in the home and the products
that contain them.
