The causes of right-sided dizziness are complex and need to be determined by the degree of dizziness occurring in the patient, as well as the triggers. If the patient experiences episodic dizziness with visual rotation when turning his head to the right side, in this case, benign paroxysmal positional vertigo, vestibular paroxysm, hypotensive vertigo, or possibly cervical vertigo, or epileptic vertigo, or other problems are mostly considered. If the patient has a history of cerebral atherosclerosis, insufficient cerebral blood supply, or cerebrovascular stenosis, the dizziness on the right side may be caused by cerebrovascular problems. If the dizziness is persistent, it may be vestibular hypofunction or a subjective symptom. Therefore, if the patient has dizziness on the right side, it is recommended to consult the hospital for examination and clarification.
