Cervical spondylosis can lead to nausea and vomiting: 1. For example, vertebral artery cervical spondylosis, due to hyperplasia of the cervical vertebrae or narrowing of the vertebral artery orifice, resulting in the vertebral artery being compressed. If the cervical spine is cold, the vertebral artery is stimulated by turning the head or lowering the head for a long time, resulting in spasm, which causes a decrease in blood supply to the brain, resulting in symptoms of vertigo, accompanied by nausea and vomiting. 2. Sympathetic cervical spondylosis, due to inflammatory lesions in the cervical spine stimulate the surrounding sympathetic nerves, resulting in sympathetic nerve inhibition or hyperactivity, which can easily lead to The symptoms of nausea and vomiting may occur, along with other symptoms such as panic, headache and dizziness. Therefore, if you have symptoms of nausea and vomiting caused by cervical spondylosis, you must go to a regular hospital in a timely manner, improve the necessary relevant examinations, clarify the severity of the condition, and then choose a targeted treatment method.
