Abstract

The control of gastric emptying has been restudied. Methods used are described. It was found that in the alert unanesthetized monkey saline is emptied from the stomach at a rate that is volume-dependent; an exponential curve results since higher volumes provoke more rapid emptying and lower volumes slower emptying. For glucose test meals emptying is quite linear; also emptying is slower and progressively slower with progressive increases in glucose concentration. There is, however, an early rapid phase of gastric emptying that converts to a slower, more linear pattern. Calories rather than osmoles appear to control emptying. Glucose in the pyloris has an inhibitory effect in gastric emptying. A theory of control is discussed. The control of gastric emptying also relates to the control of feeding.
