Nausea is the sensation of someone that he wants to vomit.
This sensation can be a result of medical conditions, but may happen to people who are exposed to provoking stimuli and respond in "motion sickness" of various types. A more detailed account of this kind of nausea is discussed under the title: "vertigo in healthy people".
When a sufferer of Meniere's disease is experiencing vertigo he may have also nausea. In severe vertigo he may have both nausea and vomiting. The mechanism of vertigo, nausea and vomiting may be helpful if the patient suffered from food poisoning. In a patient who has the nausea as part of Meniere's disease, the vomiting is not a symptom that may help him.
Since nausea may appear in many other medical conditions, the diagnosis of Meniere's disease can not be established on the basis of vertigo, nausea and vomiting. Even if there are more symptoms of Meniere's disease, it is important to do a good evaluation of the other possibilities by deep neurological assessment and gastroenterological examinations.
Follow up of the clinical picture is necessary in order to distinguish between brief episodes of acute infections and prolonged period of repeated attacks.
