ABSTRACT
Abdominal obesity is a core factor in and necessary condition of diagnosing metabolic syndrome. Abdominal fat contains two parts: subcutaneous fat and visceral fat. Both are related to hypertension, impaired fasting blood glucose, diabetes and metabolic syndrome. Current studies often focus on visceral fat, but subcutaneous fat accumulation also has an inseparable relationship. Physical and chemical changes in abdominal fat cells result in abdominal fat thickening and density increase and cause changes in secretion of adipokines in this process. The common action of the two aspects leads to a number of metabolic problems. The sanjiao dysfunction brings about abdominal accumulation of phlegm, heat and stagnant turbidity and infiltration of them into blood vessels, which are the basic pathogenesis of metabolic syndrome. Abnormal Dai Meridian function plays a key role in this process. Unblocking and regulating the Dai Meridian as a core means, promoting functional activities of qi in the whole body and especially in the middle jiao and restoring the sanjiao function help the clinical treatment of metabolic syndrome.
