Not all cervical spondylosis will cause dizziness. Vertebral artery type cervical spondylosis can cause dizziness due to the hyperostosis of the cervical spine or changes in curvature that compress one of the vertebral arteries. When patients turn their heads to one side, the compressed vertebral artery cannot compensatory increase the blood flow, which does not lead to an increase in blood supply to the brain, resulting in insufficient cerebral blood supply and causing dizziness. A typical manifestation of these patients is that turning the head to one side intensifies the dizziness due to the reasons just mentioned, which is a typical symptom of dizziness caused by vertebral artery type cervical spondylosis. For treatment, drugs that invigorate blood circulation and improve cerebral blood supply are needed, along with cervical physiotherapy treatment. Generally, avoid sitting for too long, don’t use pillows that are too high, and pay attention to protecting your cervical spine.
