Dizziness and vomiting may be caused by central vertigo and peripheral dizziness. 1. Central Vertigo: Vertigo caused by brain lesions is called central vertigo. The main lesions are mostly located in the brainstem and cerebellum. Common causes are vascular, tumor, inflammation and so on. For example, insufficient blood supply of vertebral basilar artery, thrombosis of posterior inferior cerebellar artery, brainstem tumor, brainstem encephalitis, medullary cavernous disease, multiple sclerosis, cerebellar tumors and so on. 2. Peripheral vertigo: It is due to the stimulation of the peripheral sensory organs of the vestibule, such as otolithiasis, vestibular neuronitis, Meniere’s disease, etc. Patients with otolithiasis have symptoms such as dizziness, vomiting and spinning, and patients with Meniere’s disease can be accompanied by deafness, tinnitus and other symptoms, while patients with vestibular neuronitis have a transient onset of sudden dizziness and nausea. Dizziness and vomiting patients are recommended to go to the hospital in a timely manner, after the cause of the disease is clear, according to the doctor’s guidance for standardized treatment.
