Emesis

Emesis is a medical term that refers to the act of vomiting, which is the body's way of forcefully expelling the contents of the stomach through the mouth. It can happen for various reasons, including infections, motion sickness, food poisoning, or certain medical conditions. Vomiting is often accompanied by nausea, a feeling of unease or discomfort in the stomach. While it can be a protective mechanism to eliminate harmful substances, frequent or severe vomiting can lead to dehydration and other health issues, requiring medical attention.
