Vertebral artery type cervical spondylosis may cause nausea and vomiting. This is because the vertebral artery runs through the transverse foramen in the cervical spine. If the patient has cervical disc herniation or cervical hyperostosis that compresses the vertebral artery in the transverse foramen, it can cause spasm of the vertebral artery. This leads to insufficient blood supply to the brain, resulting in symptoms such as headaches, dizziness, nausea, vomiting, and blurred vision. Once these symptoms occur, we recommend that patients first limit the movement of the cervical spine. Secondly, some drugs that improve microcirculation and alleviate cerebral ischemia can be used. Thirdly, antiemetic medications, which are also commonly used clinically, can be employed. If conservative treatment is ineffective and the condition recurs frequently, surgical treatment should be considered. (Specific medications should be used under the guidance of a doctor.)
