Because nausea occurs for such a wide variety of reasons, your doctor will seek clues to the cause of nausea in your medical history, including your medication use. It is especially helpful for you to report other symptoms that you might be having, or activities (such as eating) that trigger your nausea. If you are a sexually active woman of childbearing age, tell your doctor whether there is a possibility that you could be pregnant, the date of your last menstrual period and any type of birth control you use.
Your doctor will examine you. The exam may include blood pressure testing, an abdominal examination, neurological examination or other tests, depending on your recent symptoms and other medical history. Blood tests may be done. For any woman who could be pregnant, a pregnancy test should be done. If you have had a recent head injury, you may require a brain imaging test, such as a computed tomography (CT) scan.
