Why does nausea often accompany dizziness?

Dizziness or vertigo is indicative of a medical condition that is disturbing the balance system of the body. Mostly when the vestibular or central nervous system gets affected, the imbalance steps in. While the reasons for such system failures are many, the resultant symptom is mostly vertigo or dizziness.

Whenever one feels dizzy, most often than not, he also finds himself nauseous and sometimes vomiting. That is quite intriguing, isn’t it? Why do dizziness and nausea occur hand-in-hand?

Let’s find out.

Nausea is a sensation of uneasiness in the abdomen with an inclination to vomit. Vomiting may or may not always follow nauseating feeling.

The studies show that vestibular and central nervous system, peripheral pathways and chemoreceptor trigger zone are the four critical triggers that prompt downward signals that affect motor muscles in the gastrointestinal tract and the abdominal muscles. When the abdominal muscles tighten, the gastrointestinal tract pushes the gastric content towards the mouth, causing nausea and vomiting.

The autonomic nervous system triggers excess salivation and a sensation of unsteadiness or losing balance.

Vertigo occurs when there is the sensation of movement when actually the body is still.  The confusion triggers a sensory mismatch within the central nervous system, activating the automatic nervous system which in turn stimulates the chemoreceptor trigger zone (CTZ) initiating a feeling of nausea and vomiting.
