Which term is commonly used for vomiting?

The term "emesis" specifically refers to the act of vomiting. It is derived from the Greek word "emein," which means "to vomit." In medical terminology, emesis is often used to describe the experience of expelling contents from the stomach through the mouth, and it is a clear and widely recognized term in the healthcare field.

Nausea refers to the sensation or feeling of needing to vomit, but it does not encompass the act itself. Regurgitation describes the expulsion of food or liquid from the esophagus or stomach back into the mouth without the forceful muscle contractions associated with vomiting. Vomitus refers to the material that has been expelled during vomiting rather than the act. Understanding these distinctions is crucial in medical contexts, as each term captures a different aspect of gastrointestinal distress.
