Weight loss by means of an intragastric balloon is an advantageous procedure, as usage of such a balloon is minimally invasive and of minimal operational risk. Nevertheless, despite the encouraging results referred in to large population studies, its success rate as a treatment option is still questionable. The aim of this study was to classify and analyze all parameters recorded in a database of a treatment protocol concerning obese individuals handled by an intragastric balloon, in an attempt to delineate the comparable profile of those who succeeded to lose weight and those who failed. Retrospective data collection, including demographic and anthropometric data, social and psychological factors, educational status, and attendance at sessions and the exercise program, was conducted. Using as a criterion for grouping the percentage of excess weight loss (%EWL), the successful (%EWL ≥50%) and the poor (%EWL ≤20%) responders were identified. In total, 583 patients were assessed. Initial and ideal body weight (BW), initial body mass index (BMI), and excess weight were significantly lower in the %EWL ≥50% group (P<.001). Upon balloon removal, both groups exhibited a significant difference regarding BW, BW lost, BMI, and %EWL (P<.001). Advanced age (odds ratio [OR]=1.06; P<.001), female gender (OR=3.31; P<.001), basic educational level (OR=3.12; P<.001), and single or divorced marital status (OR=6.00; P<.001) were identified as the most powerful determinants of %EWL ≥50%. Moreover, attendance at more than four monthly interviews and strict exercise program commitment contributed significantly to a favorable outcome. Our findings could serve as an initial step for further research into factors possibly contributing to the early identification of those individuals who will notably benefit from usage of an intragastric balloon regarding BW loss.
