The phenomenon of vertigo, vomiting and nausea may be central vertigo, or it may be caused by peripheral vestibular vertigo and other factors, such as vestibular neuritis, Ménière’s disease, motion sickness and so on. 1. Central vertigo: the intracranial segment of vestibular nerve, vestibular nerve nucleus and cerebellum are the main lesions, such as cerebral lesions, acoustic neuroma and hypertensive encephalopathy. 2. Peripheral vestibular vertigo (1) Vestibular neuritis: vestibular nerve disease caused by viral infection, which leads to sudden vertigo disease, often with rotational vertigo, spontaneous nystagmus, and nausea and vomiting and other clinical symptoms. (2) Ménière’s disease: an inner ear disease characterized by idiopathic membranous labyrinthine fluid accumulation. Clinical manifestations include recurrent rotational vertigo, fluctuating sensorineural hearing loss, tinnitus, and a feeling of ear stuffiness and swelling, which is often accompanied by vomiting and nausea during acute attacks. (3) Motion sickness: it is a series of physiological reactions to the wrong perception of the motion state, which can manifest dizziness, nausea, vomiting and pallor and other symptoms, such as motion sickness, seasickness and so on. If the above symptoms occur, it is recommended to consult a doctor in time to identify the cause of the disease and actively cooperate with the doctor for treatment.
