Patients who have vertigo symptoms when they wake up mainly consider the following reasons: 1. To consider that it is caused by postural changes, this condition is mainly seen in otoliths, because the otolith particles in the balance receptors are dislodged, when patients get up in the process of head position change, the dislodged otolith particles will cause stimulation to the cell membrane of the semicircular canal, so patients will have transient vertigo; 2. To consider that it is caused by postural caused by low blood pressure, mainly seen in patients who are usually weak or have anemia or low blood pressure are more likely to appear. When the patient gets up in the process of jerking up, there will be a transient lack of cerebral perfusion and vertigo will occur; 3. If the symptoms of vertigo persist once the patient gets up, it should be considered that it may be caused by cerebrovascular diseases, such as spasm of cerebral blood vessels and insufficient blood supply to the brain, which can be clarified by doing transcranial Doppler examination.
