    Gastric emptying rates of solid food in relation to body size.

    Abstract

    The relationship of body size to rates of gastric emptying of solid food was investigated in order to obtain data that may allow this variable to be considered when populations of varying size are studied. Rates of gastric emptying were measured using a beef stew meal to which were added pieces of chicken liver tagged with [99mTc]sulfur colloid, and following the passage of the isotope through the gastrointestinal tract with intermittent gamma-imaging. Results showed an inverse linear relationship between gastric emptying rates and body surface area, and between gastric emptying rates and body weight. The variable of body size must be taken into account when measurements of gastric emptying of solid food are measured.
