What is the medical term for vomiting?

The medical term for vomiting is "emesis." This term is commonly used in healthcare settings to describe the act of expelling contents from the stomach through the mouth. It is often used in various contexts, such as "cyclic vomiting syndrome" or "post-operative emesis," to specify the condition being discussed.

Nausea refers to the sensation or feeling of needing to vomit, but it does not describe the act itself. Diarrhea is a separate condition characterized by frequent, watery bowel movements, and regurgitation typically involves the backflow of food or liquid from the esophagus to the mouth without the forceful contraction of the stomach that occurs in vomiting. Understanding these distinctions is essential for accurately communicating and identifying symptoms in medical scenarios.
