It is a common clinical symptom for patients to become dizzy first and then vomit, and there are many reasons for this: first, if the patient is suffering from vestibular nerve dysfunction, it will cause the patient to become dizzy first and then vomit, which is seen in Meniere’s disease, vestibular neuronitis, vaginitis, benign paroxysmal positional vertigo, when the patient’s vertigo will cause the autonomic nerve to be affected, it will cause the gastrointestinal tract to have abnormal movements and the gastrointestinal tract to contract Later on, it will cause the patient to vomit. Secondly, if the dizziness is severe, accompanied by inflexibility of the limbs and subsequent vomiting, it is considered to be caused by acute cerebrovascular disease, mainly due to lesions of the cerebellar brainstem, such as infarction or hemorrhage of the cerebellar brainstem. Thirdly, if the patient has increased intracranial pressure, it may also lead to dizziness followed by vomiting, and the vomiting may appear as jet-like vomiting.
