Cervical spondylosis can cause dizziness, mostly due to vertebral artery cervical spondylosis, sympathetic cervical spondylosis and mixed cervical spondylosis. Vertebral artery cervical spondylosis is likely due to the stimulation of the vertebral artery through the cervical spine by factors such as changes in the physiological curvature of the cervical spine or osteophytes, resulting in narrowing of the vertebral artery and causing a lack of blood supply to the brain, which can lead to symptoms such as dizziness. Sympathetic cervical spondylosis is a kind of cervical spondylosis with complex clinical symptoms, mainly caused by stimulation of the vegetative nerves. The specific mechanism of dizziness caused by this type is not very clear, but it may be caused by spasm of the blood vessels supplying brain tissue such as the vertebral artery and the inner ear due to stimulation of the vegetative nerves. The patient may experience a series of sympathetic symptoms such as dizziness, dizziness, tinnitus, tingling, increased blood pressure, tachycardia, anterior heart pain, etc. If a patient has a combination of the above two types of cervical spondylosis, i.e., mixed cervical spondylosis, dizziness may also occur. Clinically, dizziness caused by cervical spondylosis needs to be differentiated from other diseases that cause similar symptoms to avoid misdiagnosis and mistreatment. Dizziness caused by cervical spondylosis needs to be taken seriously and treated actively to avoid more serious consequences.
