There are more reasons for wanting to vomit and dizziness and headache, and roughly speaking, the symptoms may be caused by cervical spondylosis, insufficient cerebral blood supply and intracranial space-occupying lesions. Cervical spondylosis often causes vertigo due to herniated discs compressing vertebral arteries or nerve roots, leading to nausea and vomiting, spinning vision, dizziness and headache, and unsteady gait. For patients with hypertension, hyperlipidemia, and diabetes mellitus, the narrowing of cerebral blood vessels and insufficient blood supply to the brain usually occurs, which often manifests itself as dizziness and headache, wanting to vomit, numbness and weakness of the limbs, and transient symptoms such as impaired consciousness. When intracranial space-occupying lesions occur, such as brain tumor, brain hemorrhage, brain abscess, the intracranial pressure will increase to different degrees, resulting in headache and dizziness, nausea and vomiting, and even epilepsy, hemiplegia and other corresponding symptoms. When symptoms such as nausea, headache and dizziness occur, attention should be paid, and it is recommended to go to the Neurology Department of regular hospitals immediately, and actively give the appropriate examination and related treatment.
