I have a yellow color on my tongue what does it mean?
A yellow discoloration to your tongue is called Yellow Tongue.
It is usually a harmless problem that is temporary, but can be an
early sign of black hairy tongue (also a temporary, harmless
condition). Usually, self treatment is all that is needed for
Yellow Tongue, but you should see a doctor if the discoloration
persists or the whites of your eyes have a yellow discoloration
(sign of jaundice), too.
Yellow Tongue can also be an indication that there is a problem
with your gallbladder or liver.
