Dizziness due to insufficient blood supply to the vertebral arteries can be handled by controlling risk factors, applying medication or surgical treatment. 1. Control of risk factors: Insufficient blood supply to the vertebral artery is often caused by risk factors such as hypertension, hyperlipidemia, diabetes mellitus, or long-term smoking and alcoholism, so these risk factors should be controlled. For example, correcting bad dietary habits, going to bed early and getting up early, not staying up late, and eating a low-salt, low-sugar, low-fat diet. Insufficient blood supply to the vertebral artery caused by cervical spondylosis requires maintaining good posture and avoiding prolonged bowing of the head, such as working at a desk. 2. Application of drugs: During the attack of vertebral artery hypoperfusion, anti-platelet aggregation drugs such as clopidogrel and aspirin can be applied to prevent thrombosis. Apply statin lipid-lowering drugs such as Rosuvastatin and Simvastatin to resist atherosclerosis. At the same time, antihypertensive drugs such as Irbesartan and Nifedipine need to be applied to control the blood pressure within a reasonable range. Insufficient blood supply to vertebral artery caused by cervical spondylosis can be improved by using Chlorzoxazone and Epirubicin to improve relaxation of neck muscles in order to relieve symptoms. 3. Surgery: Apply medication by controlling the risk factors, if the treatment effect is unsatisfactory, then surgical treatment needs to be considered. Commonly used surgical procedures include endarterectomy, vertebral artery decompression, revascularization and discectomy. It is beneficial to restore the blood supply of vertebral artery and relieve dizziness symptoms. In the event of insufficient blood supply to the vertebral artery, blind self-medication should be avoided, and standardized treatment under the guidance of a doctor is required to prevent the occurrence of adverse consequences.
