Nausea is the queasy feeling that you might throw up, and vomiting is when the stomach actually empties. They are symptoms rather than a condition on their own, and common causes include stomach bugs, food poisoning, motion sickness, and pregnancy.

Common questions
Nausea & vomiting, answered.
General information, not medical advice. A provider can answer questions about your situation.
When should I worry about vomiting?
Get medical care if vomiting lasts more than a day or two, if you cannot keep any fluids down, or if you see blood. Severe belly pain, confusion, or very little urine are reasons to go to an emergency room.
Can a doctor online help with nausea?
Often, yes. A provider can ask about your symptoms, suggest ways to stay hydrated, and may prescribe something for nausea if it is appropriate. If anything points to a more serious cause, they will tell you to get in-person care.
What should I drink after throwing up?
Small, frequent sips of water or an oral rehydration drink are usually easier to keep down than large gulps. If you cannot keep even small sips down for several hours, talk to a provider.
