Vertigo on turning is probably a benign episodic positional vertigo, also known as otolithiasis, which is a peripheral vestibular disorder and is a common cause of vertigo on turning. It is caused by the dislodgement of the inner otolith and the displacement of the otolith when changing position. The vertigo can be induced when the patient is in a specific position or head position, such as leaning back or getting up, lying down, turning over, or rapid head movements. The duration of vertigo is relatively brief, typically a few seconds or 30 seconds, and can be accompanied by nausea, vomiting, nystagmus, no hearing impairment, and triggered by lack of sleep, alcohol consumption, or fatigue. The disease is self-limiting, usually resolving gradually after a few days or months, often with spontaneous remission and a good prognosis. However, if the cause is clear, the prognosis is better if it is otoliths. If it is caused by other reasons to be treated according to the cause, so positional vertigo, go to the hospital for examination in time.
