Oral glucose tolerance after either partial gastrectomy or vagotomy and pyloroplasty for duodenal ulcer was markedly affected by posture. Peak blood glucoses and the degree of reactive hypoglycaemia were greater in the erect than in the supine position. This is probably due to positional changes in gastric emptying, and our findings support the view that after gastric surgery alteration in gastric emptying rate is the main factor responsible for the change in oral glucose tolerance.
十二指肠溃疡患者行胃部分切除术或迷走神经切断术加幽门成形术后,口服葡萄糖耐量受姿势影响显著。直立位时的血糖峰值和反应性低血糖程度均高于仰卧位。这可能是由于胃排空的体位变化所致,我们的研究结果支持这样一种观点,即胃手术后胃排空率的改变是口服葡萄糖耐量变化的主要原因。
