进餐2～5小时后发生的低血糖称为饭后低血糖。可见于胃手术后或不能耐受葡萄糖的病人,第三种称反应性低血糖,其较多见但不甚明确。该疾病症状无特异性,症状的存在与口服葡萄糖后测得的血糖浓度常少关联,发病时很少测血糖,高蛋白低碳水化合物饮食后的效应作为诊断线索不可靠,故诊断很难。本研究中,作者对疑有饭后低血糖的28位病人在发作时及口服葡萄糖后测定毛细血管血糖浓度,旨在解决发作时究竟多少病人真的存在低血糖的问题,验证发作时血糖与口服糖耐量之间的关系及探讨一些症状较另一些症状更为特异的可能性。
Hypoglycemia that occurs after 2 to 5 hours of meal is called postprandial hypoglycemia. Visible in patients with gastric surgery or can not tolerate glucose, the third type of reactive hypoglycemia, which is more common but not clear. The symptoms of this disease are nonspecific. The presence of symptoms often correlates with the blood glucose level measured after oral glucose administration. Few blood glucose levels are detected at the time of onset. The effect of high protein and low carbohydrate diet is unreliable as a diagnostic clues, so diagnosis is difficult. In this study, the authors measured the postprandial hypoglycemia in 28 patients with postprandial and oral glucose determination of capillary blood glucose concentration, designed to solve the exact number of patients at the onset of hypoglycemia really exist to verify the onset of blood glucose and The relationship between oral glucose tolerance and to explore some of the symptoms more likely than some other symptoms.
