Dizziness, nausea and vomiting when lying down and turning around may be due to otoliths or Meniere’s syndrome. 1. otoliths are caused by otoliths detaching from the semicircular canal, and the patient’s dizziness is related to the rotation of the head position, which can last from a few seconds to a few minutes in most cases, and can stop suddenly and can be repeated, mainly for reset treatment. 2. patients with Meniere’s syndrome can also experience dizziness when the head position is rotated. Dizziness can also occur when the patient’s head position is not moving, and there is often fluctuating hearing loss at the same time. Most patients have a history of recurrent attacks, and the symptoms are persistent and can last for several days to a week or so.
