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 doctor will ask medical history questions, such as:
- 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?
- When did the vomiting begin? How long has it lasted?
- Does it occur several hours after meals?
- What other symptoms are also present -- abdominal pain, fever, diarrhea, poor skin turgor, other signs of dehydration, abdominal swelling, headaches?
