Dizziness when getting up from bed may be caused by a transient drop in blood pressure caused by getting up too hard. When blood pressure drops, it may cause hypoperfusion in the brain, which may easily lead to insufficient blood supply to the brain, including insufficient blood supply to the cerebellum and brainstem and insufficient blood supply to the brain. Patients with inadequate blood supply to the cerebellum and brainstem mainly present with dizziness, nausea, vomiting, balance disorders and ataxia. If the patient gets up too hard, it may also cause blood pressure to rise. When the blood pressure is severely elevated, it may cause cerebral vascular spasm, which may easily cause cerebral blood supply deficiency, and the patient may also have the above symptoms, and the blood pressure should be monitored promptly. If the patient’s blood pressure, for example, systolic blood pressure is greater than 140 mmHg and diastolic blood pressure is greater than 90 mmHg, it is generally known clinically as hypertension. If the patient has no previous history of hypertension and the patient develops hypertension with symptoms, it is recommended that blood pressure lowering treatment be given. In middle-aged and elderly patients, calcium antagonists are generally preferred, and commonly used drugs include levamlodipine and amlodipine benzoate for young people. ACEI and ARB class blood pressure-lowering drugs are mainly chosen, and commonly used drugs include Irbesartan and Enalapril. If the patient’s blood pressure is too low, it may be caused by postural hypotension, and the patient is advised to always move slowly when getting up.
