肝脏是维持血糖浓度相对恒定的重要器官,但因后天性肝病本身引起的低血糖症并不多见,通常仅见于广泛而且严重的肝细胞损害及肝功能衰竭时,如暴发性肝坏死、晚期肝硬化、原发性或转移性肝癌、上行性胆管炎及严重慢性充血性心力衰竭等。动物实验证实,肝实质损害超过80%才出现低血糖症。最近的临床观察发现,病毒性肝炎患者过度空腹后,亦可发生无症状的低血糖症,提示不甚严重 The liver is an important organ that maintains relatively constant blood glucose levels, but hypoglycemia due to acquired liver disease itself is uncommon and is usually found only in a wide range of severe liver cell damage and liver failure such as fulminant hepatic necrosis, advanced stage Cirrhosis, primary or metastatic liver cancer, ascending cholangitis and severe chronic congestive heart failure. Animal experiments confirmed that more than 80% of liver parenchymal damage before hypoglycemia. Recent clinical observations found that patients with viral hepatitis after excessive fasting, asymptomatic hypoglycemia may also occur, suggesting less serious
