Nausea and vomiting are symptoms of an underlying illness and not a specific disease. Nausea is the sensation that the stomach wants to empty itself, while vomiting (emesis) or throwing up, is the act of forcible emptying of the stomach. The term "dry heaves" refers to an episode of vomiting where there is no food in the stomach to vomit, and only clear secretions are vomited.
Vomiting is a violent act in which the stomach almost turns itself inside out - forcing itself into the lower portion of the esophagus (the tube that connects the mouth to the stomach) during a vomiting episode, expelling food and secretions.
