If hypertensive patients have dizziness, they can choose to consult the cardiology department or the neurology department. There are many reasons for dizziness in hypertension, which may be due to vasoconstriction dysfunction caused by high blood pressure, so you can mainly choose cardiology, and the symptoms of dizziness may gradually be relieved after actively controlling the blood pressure, but people with long-term hypertension may have cerebral arteriosclerosis or other conditions, so you can choose neurology to improve the craniocerebral CT and cerebral arterial ultrasound to make a clear diagnosis. The diagnosis can be made through cranial CT and color ultrasound of the blood flow in the cerebral arteries. People with high blood pressure must keep it within the standard range and pay attention to their symptoms, such as dizziness and headache, and go to the hospital for treatment in time. Some people may experience dizziness even after their blood pressure is well controlled. Medications such as nimodipine and flunarizine can be used to improve symptoms.
