Nausea and vomiting – adults: MedlinePlus Medical Encyclopedia

Nausea is feeling an urge to vomit. It is often called "being sick to your stomach."

Vomiting or throwing-up forces the contents of the stomach up through the food pipe (esophagus) and out of the mouth.

Once your health care provider finds the cause, you will want to know

how to treat your nausea or vomiting

.

You may need to:

Take medicine.

Change your diet, or try other things to make you feel better.

Drink small amounts of

clear liquids

often.

Stop taking medicines that might be causing the nausea and vomiting

If you have morning sickness during pregnancy, ask your provider about possible treatments.

The following may help treat motion sickness:

Remaining still.

Taking over-the-counter antihistamines, such as dimenhydrinate (Dramamine).

Using prescription scopolamine skin patches (such as Transderm Scop). These are helpful for extended trips, such as an ocean voyage. Use the patch as your provider instructs. Scopolamine is for adults only. It should NOT be given to children.

Call 911 or the local emergency number or go to an emergency room if you:

What medicines do you take?

Did other people who ate at the same place as you have the same symptoms?

Are you pregnant or could you be pregnant?

Do you use marijuana? If yes, how often do you use it?

Diagnostic tests that may be performed include:
