答:人体内缺乏胰岛素时,会引起体内糖代谢障碍。不仅使进入组织细胞的葡萄糖大为减少,而且会抑制血糖合成糖元,促进肝糖元分解和糖的异生(由蛋白质、脂肪等非糖类物质转变成糖类物质),使血糖浓度显著升高。当血糖浓度超过150—180毫克/100毫升时,多余的糖就从尿中排出,或为糖尿病。由于糖具有一定的渗透压,在排泄过程中必然要带出大量水分,引起渗透性利尿,从而出现多尿现象。渗透性利尿导致体内丢失大量水分,引起烦渴感觉,因而病人常需饮大量的水。人体内缺乏胰岛素,使葡萄糖的合成和分解过程受到抑制,妨碍了组织细胞对葡萄糖的
A: The body’s lack of insulin, can cause glucose metabolism disorders in the body. Not only the glucose into the tissue cells is greatly reduced, but also inhibit glycogen synthesis of glycogen, glycogen and promote hepatic glycogenysis of heterogeneous (from protein, fat and other non-carbohydrate substances into carbohydrates), the blood glucose concentration significantly Rise. When the blood sugar concentration exceeds 150-180 mg / 100 ml, excess sugar is excreted from the urine, or is diabetes. As the sugar has a certain degree of osmotic pressure, in the process of excretion will inevitably bring a lot of water, causing diarrhea, resulting in polyuria phenomenon. Permeable diuresis causes the body to lose a lot of water, causing polydipsia, so patients often need to drink plenty of water. The lack of insulin in the human body inhibits the process of glucose synthesis and decomposition, hindering the effect of tissue cells on glucose
