What is Nausea ?
Nausea is a general term describing a queasy stomach, with or without the feeling that you are about to vomit. Almost everyone experiences nausea at some time, making it one of the most common problems in medicine. Nausea is not a disease, but a symptom of many different disorders.
Causes of Nausea
It is caused by problems in any one of three parts of the body, including:
- Abdominal and pelvic organs
- Brain and spinal fluid
- Balance centers in the inner ear
Symptoms of Nausea
When the body prepares to vomit, the following sequence may occur:
- The muscular ring between the esophagus and stomach (esophageal sphincter) relaxes.
- The abdominal muscles and diaphragm contract.
If vomiting occurs, the stomach contents are expelled through the esophagus and mouth.
- The windpipe (larynx) closes.
- The lower portion of the stomach contracts
Diagnosis of Nausea
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.
