Inversion is not able to treat cerebral insufficiency of blood supply, which is caused by atherosclerotic stenosis of the arteries in the brain. Because of the narrowing of the cerebral blood vessels, the blood supply to the brain is relatively insufficient, and the focus of treatment is on taking anti-platelet drugs, lipid-lowering drugs, and drugs to improve microcirculation. When inverted only due to the effect of gravity, cerebral venous blood to the heart receives a certain resistance. But at this time the arteries are still relatively ischemic state, inversion can not play any therapeutic role. Prolonged inversion will lead to stasis of blood in the veins of the head and face, and there is a risk of congestion, capillary rupture and blood out of the head and face. Treatment of cerebral insufficiency of blood supply requires control of blood pressure and blood sugar in addition to oral administration of the above mentioned drugs. Do not blindly try unscientific advice after suffering from cerebral blood supply deficiency, as long as regular medication, cerebral blood supply deficiency can be treated.
