Nausea is usually the body's message that we have ingested a toxin or for some reason now is not a good time to be eating. Sometimes nervousness affects nausea, too.

When nausea occurs it can be caused by to much food or beverage in the stomach. Eating foods that are to greasy or are to acidic and cause the lining of the stomach to become iritated. Nausea can be felt when pregnant and the hormones in the body change. Chemo therapy affects the lining of the stomach an causes nausea.
