Satiety after vertical banded gastroplasty

Early satiety following gastroplasty is due to the new anatomic conditions created by the operation and refers to a distressing or painful epigastric sensation after food consumption. Early satiation may act as an aversive stimulus, shaping eating habits and behaviour in such a way as to promote satisfactory weight loss and maintenance. This hypothesis was tested in patients who had undergone vertical banded gastroplasty (VBG). The duration of the sensation of early satiety was associated with the scores of questionnaires assessing eating behaviour, but seemed to be completely unrelated to the radiologically measured proximal pouch volume, energy intake and weight loss data. These findings suggest that cognitive factors play a substantial role in determining food intake and therefore in achieving weight goals following gastric restriction.
