Poor blood circulation in the brain, also known as cerebral hypoperfusion, can cause clinical symptoms such as dizziness, rotating vision, nausea, vomiting, and unstable walking. For cerebral insufficiency of blood supply, we can improve the circulation, either by oral or intravenous infusion of drugs to improve circulation, or by platelet aggregation inhibition therapy, such as oral aspirin, etc. In addition to the above symptomatic treatment, clinical treatment should be based on the root cause of cerebral insufficiency, which is atherosclerosis. The risk factors for atherosclerosis are related to hypertension, diabetes, dyslipidemia, hyperhomocysteinemia, smoking, alcohol consumption, obesity, lack of physical activity, age and other risks. The way to improve brain circulation is to control blood pressure, blood sugar, lipid standards, quit smoking, quit drinking, control weight, and exercise properly.
