Nausea is that feeling you have when you are going

not know how to describe the feeling. Vomiting
(emesis) is throwing up what is in your stomach. It
usually comes out of your mouth and can also come
out through your nose. You can gag or try to bring up
the contents of the stomach but nothing comes out.
This is called dry heaving. Nausea and vomiting can
happen together or one without the other.
