A sudden or significant increase in blood pressure can cause dizziness, but it is important to note that blood pressure can also be significantly elevated when combined with cerebrovascular disease. Therefore, when a patient with hypertension experiences dizziness, it is necessary to first rule out serious conditions such as cerebrovascular disease, and blood pressure can be controlled to determine the absence of comorbidities, which can often relieve dizziness. If dizziness is still present after blood pressure control, it is suggested that hypertension and dizziness are not well related, so it is recommended to go to neurology, otorhinolaryngology, etc. for further consultation to investigate the causes of dizziness caused by other sources of disease and to deal with them accordingly. Patients with hypertension are highly susceptible to atherosclerosis of the cerebral arteries, and the vertebrobasilar artery is the main artery supplying blood to the cerebellum and brainstem. Inadequate blood supply to the vertebrobasilar artery can easily cause transient ischemic attacks in the cerebellar region. The cerebellum is involved in the regulation of somatic balance and muscle tone, as well as the coordination of random movements. When the cerebellum is ischemic, the above functions are affected, and patients may experience vertigo and dizziness, unsteadiness in walking, vomiting, and tinnitus, with a high incidence of vertigo in particular. When accompanied by blurred vision, diplopia, hearing loss, slurred speech, difficulty in swallowing, abnormal sensation in the face and limbs, and transient disorders of consciousness are more helpful for diagnosis. After cerebrovascular accident is clearly excluded, medication should be applied to lower the blood pressure. In the acute phase, intravenous antihypertensive drugs can be actively lowered. After the acute phase, angiotensin II receptor blockers, long-acting calcium channel blockers, angiotensin converting enzyme inhibitors, diuretics, etc. can be chosen. And at the same time, symptomatic management of headache can be done, such as taking Cipro, etc.
