Eight Billroth II resected patients and 8 normal controls were given two oral glucose loads, one ingested within 2 min, and the other ingested slowly over 80 min. In the Billroth II resected group, the integrated plasma GIP release was significantly higher after the fast than after the slow glucose ingestion. In this group the integrated plasma GIP release was also significantly higher than in the control group, but only after the fast glucose ingestion. These findings indicate that the rate of glucose delivery into the intestine may be of importance in the plasma GIP response to oral glucose.
