Wanting to vomit like motion sickness may be due to Meniere’s disease, cerebral blood supply insufficiency, hypertension, vestibular neuronitis, otolithiasis and other causes.
1. Ménière’s disease: this disease is related to the mechanical obstruction of the lymphatic vessels of the inner ear and the obstruction of lymphatic absorption in the inner ear leading to the accumulation of water in the labyrinth of the inner eardrum, and the clinical manifestations are recurrent vertigo (a sense of heavenly rotation), tinnitus, hearing loss, nausea, vomiting and other symptoms.
2. Insufficient blood supply to the brain: atherosclerotic lesions of vertebral basilar artery and internal carotid artery, cervical spondylosis and other factors lead to insufficient blood supply to the brain, and the above symptoms are caused by ischemia and hypoxia of brain cells.
3. Hypertension: In severe hypertension, especially hypertensive emergency, the pressure of cerebral blood vessel wall increases significantly, and even intracranial pressure rises, leading to severe headache, dizziness, nausea, vomiting and other symptoms.
4. Vestibular neuronitis: viral infection, bacterial infection and other factors lead to inflammatory lesions of vestibular neurons, and sudden onset of vertigo, nystagmus, nausea, vomiting and other symptoms occur after vestibular nerve function is impaired.
5. Otolithiasis: It is also called benign paroxysmal positional vertigo, which belongs to peripheral vestibular neuropathy, and the attack is characterized by vertigo that is closely related to a certain posture and lasts for a short period of time, about tens of seconds.
The urge to vomit like motion sickness may be related to a variety of factors, and it is recommended to consult a doctor for a clear diagnosis.
