Nausea and vomiting: Nausea is a feeling of uneasiness of the stomach that often comes before vomiting. On the other hand, vomiting is the forcible voluntary or involuntary emptying of stomach contents through the mouth. In short, nausea and vomiting are not diseases but are symptoms of many conditions like infections, motion sickness, an early stage of pregnancy, and gastroparesis (slow stomach emptying). A receptor located in the brain known as the chemoreceptor trigger zone (CTZ) controls vomiting.
