If you experience dizziness, nausea and vomiting, it is recommended that you consult a neurologist for treatment. There are many causes for the above symptoms, which need to be examined by the doctor and combined with relevant auxiliary examinations for differential diagnosis. If the dizziness has obvious correlation with the body position, which is more obvious when lying down and getting up, or when turning over, and there is a sense of severe vertigo, which lasts for a short period of time, usually not more than 1-2 minutes, it is considered to be benign paroxysmal positional vertigo with a higher probability. If dizziness and vomiting are accompanied by a headache, a past history of migraine, and a characteristic fear of sound and light, vestibular migraine is considered more likely. If there are previous risk factors for cerebrovascular disease, such as hypertension, diabetes mellitus, etc., and the dizziness lasts for a longer period of time, it is considered to be posterior circulation ischemia and cerebral infarction without exception, and further investigation of cranial CT and head MRI is needed to confirm the diagnosis.
