胰岛素瘤是一较少见的疾病,属胰岛细胞六种内分泌瘤之一,曾称为胰岛细胞瘤或功能性胰岛细胞瘤。因其以患者体内胰岛β细胞无控制的释放胰岛素为特征,故称胰岛素瘤或胰岛β细胞瘤较为确切。胰岛素瘤患者,可反复出现发作性低血糖状态。神经系统能量的主要来源为葡萄糖,而其本身糖元储存甚少,故对低血糖最为敏感,易于发生神经系统损害症状。 Insulinoma is a rare disease that belongs to one of the six endocrine neoplasms of pancreatic islets, which has been called islet cell tumors or functional islet cell tumors. Because of its non-controlled release of insulin in patients with pancreatic islet β cells characterized, so that insulinoma or pancreatic β-cell tumor more accurate. Patients with insulinoma, episodes of episodes of hypoglycemia can be repeated. The main source of energy for the nervous system is glucose, and its own glycogen storage is very small, so the most sensitive to hypoglycemia, prone to nervous system damage symptoms.
