Nausea and vomiting are common symptoms that can be caused by numerous conditions. Nausea and vomiting most often are due to viral gastroenteritis — often mistakenly termed "stomach flu" — or the morning sickness of early pregnancy.

Many medications can cause nausea and vomiting, as can general anesthesia for surgery. Rarely, nausea and vomiting may indicate a serious or even life-threatening problem.
