A bad cervical spine does not cause hypertension. Hypertension is divided into primary hypertension and secondary hypertension, the former accounts for 95% and the cause is not clear, and genetics, diet, and emotions are related. Secondary hypertension is mostly secondary to kidney disease and is related to endocrine changes. Therefore, cervical spondylosis does not cause hypertension. If the cervical spine is bad, it may cause insufficient blood supply to the brain, resulting in dizziness, headache, numbness in the arms and other symptoms, and may also cause a temporary increase in compensatory blood pressure. If it is hypertension, it is recommended to exclude secondary hypertension, control blood pressure in a timely manner, pay attention to eating more vegetarian and less meat, strengthen exercise, pay attention to rest, do not stay up late, and do more cervical spine activities.
