[Preoperative eating behavior and weight loss after gastric banding for obesity].
The relationships between the cognitive restraint and the tendency to disinhibition prior to gastric banding for obesity, as assessed by the Three Factor Eating Questionnaire, and the weight loss at one year following the operation were investigated. The amount of overall weight loss was correlated positively to the disinhibition and negatively to the cognitive restraint score. When the food consumption overtakes the proximal gastric pouch capacity, the patient feels a strong aversive stimulus, thus stopping eating. Therefore, more is the patient's tendency to lose the control on food intake more is the postoperative weight loss. On the contrary, the high restraint patient only seldom feels such an aversive stimulus, and only seldom stops eating, thus the weight loss is smaller. Except for the overeating due to the disinhibition, the aversive stimulus arising from the gastric restriction cannot influence by itself any other aspect of eating behavior.
