Transient dizziness when lowering or shaking the head may be related to benign paroxysmal positional vertigo, cerebral blood supply insufficiency, cervical spondylosis, and so on.
1. Benign paroxysmal positional vertigo: also known as otolithiasis, usually occurs when there is a change in head position, and the duration of dizziness is relatively short, not more than 60 seconds, which may be accompanied by nausea, visual rotation and other symptoms.
2. Insufficient cerebral blood supply: if you suffer from hypertension, cerebral atherosclerosis and other diseases, carotid plaques may appear, resulting in insufficient cerebral blood supply and dizziness symptoms.
3. Cervical spondylosis: If the cervical disc is herniated, the protruding disc may compress the nerves and blood vessels in the cervical spine, which may cause dizziness.
The symptoms of dizziness may also be caused by other diseases, so it is recommended to go to the examination in time and find out the cause of dizziness under the guidance of the doctor.
