When people reach old age, endocrine decreases, especially hormone decreases, which slows down human metabolism, and human metabolic wastes cannot be eliminated, accumulating in cells, making cells in sub-health state and fat metabolism disorder more serious; The so-called cerebrovascular sclerosis refers to that the vascular wall of cerebral artery is damaged by lipid deposition and intima, and platelets, cellulose and other substances accumulate on the intima of the damaged vascular wall, which makes the connective tissue of the vascular wall proliferate, the intima is rough, the elasticity decreases, the lumen is narrow, and even affects the normal blood circulation and oxygen supply, thus producing clinical symptoms. Cerebral arteriosclerosis and cerebral thrombosis are mainly caused by hypertension, hyperlipidemia and high blood viscosity; And thickening, deposition and coagulation of the inner wall of blood vessels; Inflammatory injury and degenerative changes in the inner wall of blood vessels block the passage of blood flow, causing long-term hypoxia and ischemia in the brain, causing a series of symptoms, and cerebral infarction induced by emotional excitement and other factors. Therefore, it is necessary to prevent cerebrovascular diseases as soon as possible.
