Sudden dizziness and nausea may be caused by abnormal blood pressure, increase or decrease of blood pressure. Blood pressure should be monitored. If there is abnormal blood pressure, it should be actively regulated. Patients with elevated blood pressure should use long-acting drugs to keep their blood pressure stable as far as possible, instead of going from high to low. If the patient has a transient ischemic attack of the posterior circulation, it can also be caused. Its symptoms are paroxysmal, and the duration is mostly 10-15 minutes. Brain CT examination is normal, which is mostly seen in middle-aged and elderly people. Common causes include cerebral atherosclerosis, diabetes and hyperlipidemia. If there is vascular stenosis, it may also be caused under certain stress conditions. If the patient has cerebellar and brainstem diseases, such as cerebral infarction and cerebral hemorrhage, they can also appear. At the same time, balance disorder and ataxia may occur, and the symptoms are persistent. If necessary, check brain CT or brain MRI to make sure.
