Abstract

The response of the gastric electric activity to liquid and solid meals is investigated. It is shown that the frequency of the slow wave increases significantly after eating. It may result in faster contractions of the stomach. It is argued that the amplitude increase in the postprandial electrogastrogram (EGG) is due to both gastric contractions and gastric distention bringing the stomach closer to the cutaneous electrodes located on the abdomen. The different durations of increased power of the slow wave in the post-water EGG and in the postprandial EGG suggest that the evolution of the postprandial slow wave correlates with the different gastric emptying characteristics for water and a solid meal, respectively.
