糖尿病是一种由遗传和环境因素相互作用,引起体内胰岛素相对或绝对不足,造成血糖升高的代谢性疾病,病人如未经治疗,排出的尿中常含有糖(尿液变甜)。但是,这并不是说凡尿中含糖的都是糖尿病患者。以下情况都有可能出现糖尿,但它们并非糖尿病所致。 肾性糖尿 正常人血液流经肾脏时,血中的葡萄糖等许多物质都会通过肾小球滤出,再由肾小管选择性地重吸收返回体内加工利用。当血糖浓度在正常范围内时,肾小球滤液中的葡萄糖基本上会被重吸
Diabetes mellitus is a metabolic disease caused by the interaction of genetic and environmental factors, causing the relative or absolute deficiency of insulin in the body and causing hyperglycemia. Untreated urine usually contains sugar (urine sweetening). However, this is not to say that all people with diabetes who have sugary sugars in the urine. Diabetes may occur in the following situations, but they are not caused by diabetes. Renal diabetic normal blood flow through the kidneys, many of the blood glucose and other substances will be filtered through the glomerular, and then selectively reabsorbed by the renal tubules back to the body processing and utilization. When the blood glucose concentration is within the normal range, the glucose in the glomerular filtrate is essentially reabsorbed
