If a patient wakes up early in the morning with dizziness and vomiting, the following causes should be considered: First, if it is accompanied by ataxia such as unstable walking, cerebellar lesions, such as sudden cerebellar infarction or cerebellar hemorrhage, should be considered, so as to avoid delaying the disease. Secondly, if the patient wakes up early in the morning with dizziness and vomiting associated with changes in the position of the head and presents brief episodes, it should be considered to be caused by benign paroxysmal positional vertigo. In the third aspect, if it is accompanied by tinnitus and stuffy ears, it should be considered as an attack of Ménière’s disease, in which patients with Ménière’s disease present with recurrent episodes of dizziness accompanied by fluctuating hearing loss in clinical practice. The fourth aspect may also be related to elevated blood pressure. It is recommended that blood pressure be measured to clarify that if the patient has a history of hypertension, fluctuating blood pressure, and irregular application of antihypertensive drugs, morning dizziness and vomiting may occur.
