Metabolic syndrome is a state in which cardiovascular disease risk factors associated with metabolic abnormalities are clustered within an individual, with obesity and insulin resistance at its center. Individuals with metabolic syndrome are at high risk for developing cardiovascular disease. The etiology of the metabolic syndrome is unknown. At present, it is generally believed that insulin resistance is the central link of metabolic syndrome, and obesity is closely related to the occurrence of insulin resistance. Treatment of metabolic syndrome is primarily aimed at preventing type 2 diabetes and cardiovascular disease. Once there is metabolic syndrome, it is necessary to improve the lifestyle behavior, increase physical exercise and reduce weight, which is conducive to the prevention of cardiovascular and cerebrovascular diseases. In addition to exercise and weight loss, metabolic syndrome can also control blood glucose levels under the guidance of a doctor to delay the onset of diabetes.
