The direct cause of dizziness is the blood supply to the vestibular nerve. The vestibular blood supply system is like a field on a hill that needs to be irrigated by pumping water from the bottom of the hill. If the water cannot be pumped up or is not pumped enough, it needs to be checked from various aspects to see if there are any problems, maybe the pumping power is not enough (heart), maybe the water pipes (blood vessels) are narrowed or not working at that place, or maybe the water impurities (blood) are too much and too thick to flow. In the human body that affects the blood supply, including the pump (like the engine to provide kinetic energy, the human heart) and access (cardiovascular, vertebral artery, vertebral basilar artery, intracranial cerebral vessels), whether the blood vessels are smooth, elasticity is good, and with the human cardiovascular, cerebrovascular and blood viscosity, whether there is hypertension, hyperlipidemia, diabetes, anemia, chronic cardiac insufficiency, cerebrovascular atherosclerosis, cerebrovascular stenosis The age of the person, the vertebral artery stenosis, compression and so on may be related, so there are many factors to consider. It is not a department that can be cured by one or two outpatient visits or one or two hospital stays, but usually requires clear examination of the cause and then targeted treatment, and overall comprehensive treatment should be considered. These are only treatment principles and ideas, the specific program needs to be developed by a specialist. It is recommended to consult with neurology (cerebrovascular medicine) and otorhinolaryngology because the problems are more frequent in cerebral vascular sclerosis and ENT, such as benign postural vertigo and Meniere’s syndrome. Then, the orthopedic spine specialist should be consulted to identify the cause of the disease and then provide targeted treatment. In orthopedics, it is not arbitrary to say that dizziness is caused by cervical spondylosis after taking an X-ray of the cervical spine and seeing “osteophytes and cervical degeneration”. If dizziness is caused by cervical spondylosis, it generally has the following characteristics: first, there is the general manifestation of cervical spondylosis, that is, neck pain, restricted movement, sometimes accompanied by numbness or pain in the shoulders and arms, and the symptoms are aggravated by improper sleeping posture. The dizziness is obviously related to the neck activity, and the dizziness will be reduced or relieved when the neck is not moving. Suddenly turning the head will cause sudden collapse, that is, sudden blackness and fainting in front of the eyes, and generally there is no nystagmus of cerebrovascular disease and ear, nose and throat disease.
