Effect of age on gastric emptying of liquid--solid meals in man. 1983

J G Moore, and C Tweedy, and P E Christian, and F L Datz

A dual radioisotopic method was employed to study the rate of gastric emptying of meals in ten males with an average age of 31 years and 10 elderly males with an average age of 76.4 years. All study subjects were fed a standardized 900-g meal labeled with a liquid (111indium-DTPA) and solid (99mtechnetium-tagged liver) phase isotopic marker. There were no significant differences in solid food emptying rates between the young and aged men. A delay in liquid emptying, however, was observed in the aged men. The clinical significance of this observation is unknown.
