You are not in any immediate danger. This is NOT an A&E
case.
Yes, how the heck did you manage to swallow a 50 cent coin? Well if
you're certain you did swallow one, then perhaps you should consult
a doctor. The coin might become an intestinal obstruction. Or it is
also possible for the coin to be discharged thru normal means
(passing motion). Time frame for discharge is about 24hrs.
However, if you chose not to consult a doctor, please look out for
the following symptoms.
*Abdominal pain.
*Vomitting.
*Pain while trying to pass motion.
*Bleeding from the rectum.
*Any combination or all of the above.
These symptoms might only occur after 24hrs or more when your
intestine becomes fully or partially blocked.
Would recommend you DO consult a doctor just to be safe.
