肝脏对调节机体糖类代谢起着重要作用,当血糖升高时可合成肝糖原贮存,抑制糖原异生,并可使糖类转化为脂类及非必需氨基酸等;当血糖降低时又可将肝糖原分解为葡萄糖,加速糖原异生以维持血糖浓度。故肝功能异常即可引起糖类代谢障碍,既可出现高血糖又可出现低血糖,而以前者多见。继发肝实质损害的糖尿病称为肝原性糖尿病。其发病率,慢性肝病有糖耐量减退 The liver plays an important role in the regulation of carbohydrate metabolism in the body. When the blood sugar is elevated, it can synthesize glycogen storage, inhibit gluconeogenesis and convert carbohydrates into lipids and non-essential amino acids. When the blood sugar is reduced Liver glycogen can be broken down into glucose, accelerate gluconeogenesis in order to maintain blood glucose levels. Therefore, abnormal liver function can cause carbohydrate dysfunction, both high blood sugar and low blood sugar can occur, while the former more common. Diabetes secondary to liver parenchymal damage is called hepatic diabetes. Its incidence, chronic liver disease impaired glucose tolerance
