What is the difference between nausea and vomiting?
It seems to me that they are the same thing, aren't they?
Thanks for help.

Nausea is the feeling before you do the actual throwing up of all you´ve eaten.

They are not the same. "nausea" is the unpleasant feeling that you usually have before you vomit. "vomiting" is the act of expelling stomach contents out through your mouth.
