摘要低血糖是儿童常见的代谢紊乱,其发病率约为10％,其中遗传相关疾病的发生率为1/30 000～10/30000.近年来发现越来越多的导致低血糖的遗传性疾病,患有该病的患儿最早可能具有轻度神经系统损害,重者出现肝性脑病、呼吸衰竭、精神错乱,甚至死亡.因此,低血糖相关遗传病的研究越来越受到重视,但低血糖的诊断和鉴别诊断尚未形成统一共识.现就该类相关疾病的诊断和治疗作一综述,以期对临床实践起指导作用.

abstractsHypoglycemia is a common metabolic disorder in children,and its incidence is about 10％.Among them,the incidence of hereditary related diseases is about 1/30 000-10/30 000.More and more genetic diseases leading to hypoglycemia have been discovered in recent years.Children with the disease may have mild nervous system damage at the earliest stage,and liver encephalopathy,respiratory failure,confusion or even death in severe cases.Therefore,more and more attention has been paid to the study of hypoglycemia related genetic diseases,but the diagnosis and differential diagnosis of hypoglycemia has not yet formed an unified consensus.Now,the diagnosis and treatment of this kind of related diseases were summarized in order to provide data for clinical practice.
