Abstract

The effects of hyperglycemia on pancreatic, biliary, and gastric secretory responses to meals have not been hitherto quantified in man. In the present study seven normal volunteers were fed on two occasions a 500-ml liquid test meal containing fat and protein. During one of the meals the subjects were made acutely hyperglycemic with intravenous glucose, whereas in control experiments, each subject received intravenous saline in place of glucose. A jejunal perfusion method was used to measure pancreatic outputs of trypsin and biliary outputs of bile salts for 150 min after the meal; the same method was used to quantify indirectly the amount of acid secreted by the stomach in the 150-min period. Serum gastrins were also measured basally and at intervals after the meal. Hyperglycemia suppressed serum gastrin, gastric acid production, trypsin secretion, and bile salt output in response to the test meal.
