Nausea and vomiting are common signs and symptoms that can be caused by numerous conditions. Nausea and vomiting most often are due to viral gastroenteritis — often mistakenly called 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.
The causes of nausea and vomiting are quite similar. Many things can bring on nausea. Some common causes are:
- Other motion sicknesses
- Early pregnancy
- Intense pain
- Exposure to chemical toxins
- Emotional stress (fear)
- Gallbladder disease
- Food poisoning
- Various viruses
- Certain smells or odours
When should a doctor be consulted?
Are there complications from prolonged nausea or vomiting?
Persistent vomiting combined with diarrhea can result in dehydration. More aggressive treatment may be necessary for younger children or anyone with severe dehydration.
