Some types of cervical spondylosis can cause dizziness symptoms, but other factors need to be ruled out as well. There are many clinical subtypes of cervical spondylosis, and dizziness can occur when a patient has sympathetic cervical spondylosis and vertebral artery cervical spondylosis. Among them, dizziness caused by vertebral artery cervical spondylosis is mainly due to the narrowing of the vertebral artery lumen, which causes insufficient blood supply to the vertebral basilar artery. Sympathetic cervical spondylosis, on the other hand, is mainly caused by various lesions that stimulate the nerves in the neck, resulting in dizziness due to plant nerve dysfunction, which may be accompanied by nausea, vomiting, diarrhea, abdominal pain, sweating and other manifestations. Patients can also cause dizziness when certain diseases exist in the body, such as otoliths and Meniere’s disease, which need to be differentiated. Patients are advised to go to the orthopedic department of the hospital for examination in a timely manner to clarify the specific causes and to carry out standardized treatment under the guidance of a doctor.
