Abstract

Using information about the volume and energy density of meals, results from the literature on gastric emptying for healthy men can be marshalled into a consistent body. The same process applied to the published papers on men with duodenal ulcer shows that they have abnormally rapid gastric emptying, especially for meals of high-energy density. This provides confirmation of the view of Shay (1944) that the slowing of gastric emptying by duodenal receptors is less in men with duodenal ulcer than it is in healthy men.
