Three-Dimensional Model Improves Body Image Perception After Bariatric Surgery

TL;DR

A 3D modeling tool helps bariatric surgery patients better perceive their post-surgery body image, potentially improving their mental health and recovery.

Contribution

Introduces a 3D modeling tool as a novel, non-invasive method to enhance body image perception after bariatric surgery.

Findings

Nearly half of the participants changed their body perception after using the 3D modeling tool.

One third of participants reduced their FRS score after visualizing their 3D avatar.

The correlation between FRS score and BMI was stronger after using the 3D modeling tool.

Abstract

Background: Despite losing weight, the majority of subjects retained an obese view of themselves. The aim of the study was to evaluate the usefulness of a 3D modeling tool in improving the body image of patients who have undergone bariatric surgery. Methods: Morbidly obese subjects involved in a medico-surgical obesity management program and having undergone a Roux en Y Gastric Bypass (RYGB) or a sleeve gastrectomy (SG) were prospectively included during their usual postoperative medical follow-up. The figure rating scale (FRS), body image questionnaire, and Hospital Anxiety Depression Scale test were performed. The FRS was assessed before and after visualizing their body image using a 3D modeling tool. Distributions between the groups for gender (female vs. male) and type of surgery (gastric bypass vs. sleeve gastrectomy) were tested with a Pearson’s chi2 independence test. The significance threshold was p < 0.05. Results: We included 140 adults with sleeve gastrectomy (72.9%; n = 102) or gastric bypass (27.1%; n = 38). The mean time from surgery was 308.3 ± 111.4 days (63–511). Participants were mostly female (77.9%; n = 109). Nearly half of the subjects who had undergone bariatric surgery almost one year before modified their body perception after visualizing their avatar thanks to a 3D modeling tool. One third reduced their FRS score (“perceived body”) after visualizing their avatar. FRS score and body mass index (BMI) following surgery (“real body”) were significantly correlated before and after visualizing the 3D avatar, with a stronger correlation after visualizing the 3D avatar. Conclusions: A 3D modeling tool may improve body perception after weight loss in subjects with bariatric surgery. Being simple, non-invasive, not expansive, and easy to use during a consultation and to understand for the patient, a regular use of this tool may be largely implemented in clinical practice. Its usefulness in improving body image, mood disorders, and eating disorders and the further success of the surgery should be further evaluated.
