What is nausea and vomiting?

Nausea is an unpleasant feeling in the back of your throat and stomach that may lead to vomiting. Some other ways people describe nausea are sick to my stomach, queasy, or upset stomach. Other symptoms that may happen along with nausea are increased saliva (spit), dizziness, light-headedness, trouble swallowing, skin temperature changes, and a fast heart rate.

People often refer to vomiting as “throwing up.” When you vomit, your stomach muscles contract (squeeze) and push the contents of your stomach out through your mouth. You might or might not feel nauseated.

Sometimes people retch. This is when you try to vomit without bringing anything up from your stomach. Other words used to describe retching are gagging or dry heaves.

Nausea and vomiting often happen at the same time, but they can be 2 different problems.
