'''Nausea''' is the sensation of having an urge to [[vomit]]. Vomiting is forcing the contents of the stomach up through the [[esophagus]] and out of the [[mouth]]. The body has a few main ways to respond to an ever-changing, wide variety of invaders and irritants. Sneezing ejects the intruders from the [[nose]], [[cough]]ing from the [[lung]]s and [[throat]], [[diarrhea]] from the [[intestine]]s, and vomiting from the [[stomach]].

Vomiting is a forceful action accomplished by a fierce, disgusting contraction of the [[diaphragm]]. At the same time, the abdominal [[muscle]]s tighten against a relaxed stomach with an open "cardiac [[sphincter]]". The contents of the stomach are propelled up and out. [[Saliva]]tion may increase just before vomiting. Vomiting is a complex, coordinated [[reflex]] orchestrated by the vomiting center of the [[brain]]. It responds to signals coming from:
 
−
* The [[mouth]], [[stomach]], and [[intestine]]s
 
−
* The balancing systems in the ear (motion sickness)
 
−
* The brain itself, including unsettling sights, smells, or thoughts

An amazing variety of situations can trigger vomiting, from a [[migraine headache]] to a [[roller coaster]] ride to a spoon down the back of the throat, (this stimulates the gag reflex). Sometimes, just seeing someone else vomit will start one vomiting. One should remember, however, that vomiting is common. Almost all children will vomit several times a year during their childhood. In most cases, it is due to a viral gastrointestinal infection or simply eating too much candy.
