You should also call if:

• A young child is lethargic or has marked irritability.
• An infant vomits repeatedly.
• A child is unable to retain any fluids for 8 hours or more.
• Vomiting is recurrent.
• An adult is unable to retain any fluids for 12 hours or more.
• There is a decrease in urination (including a baby who is not wetting the normal amount of diapers).
• Nausea persists for a prolonged period of time (in a person who is not pregnant).

Your health care provider will perform a physical examination, particularly to look for signs of dehydration.

To help diagnose the cause of the nausea or vomiting, your health care provider will ask medical history questions, such as:

• When did the vomiting begin? How long has it lasted?
• Does it occur several hours after meals?
• What other symptoms are present -- abdominal pain, fever, diarrhea, poor skin turgor, other signs of dehydration, abdominal swelling, headaches?
• Are you vomiting fresh blood? Do you have repeated episodes of vomiting blood?
• Are you vomiting material that looks like coffee grounds?
• Are you vomiting undigested food?
• Are you vomiting greenish material?
• Is the nausea or vomiting severe enough to cause unintentional weight loss?
• Is the vomiting self-induced?
• Have you been traveling? Where?
• What medications do you take?
• Did other people that ate at the same location as you have the same symptoms?
• Are you pregnant or could you be pregnant?

The following diagnostic tests may be performed:

• Blood tests (such as CBC with differential, blood electrolyte levels, and liver function tests)
• Urinalysis
• X-rays of the abdomen

If dehydration is severe, you may need intravenous fluids. This may require hospitalization, although it can often be done in a doctor's office. Antivomiting drugs (anti-emetics) may be helpful but they should be used only when the potential benefits outweigh the risks.
