Raises a question worth testing. It does not answer one.
This narrative review proposes that difficulties in body schema updating—rather than body image disturbance alone—may explain the persistent perception of obesity some patients retain after substantial post-bariatric weight loss. The authors acknowledge this remains a hypothesis unsupported by direct empirical investigation in bariatric populations and highlight a critical gap in the literature requiring future research.
Narrative review. Individuals undergoing bariatric surgery for severe obesity, with emphasis on those experiencing post-operative body image disturbance or difficulties adapting to bodily changes..
Some individuals following bariatric surgery experience persistent perception of themselves as obese despite substantial weight loss, inconsistent with objective physical transformation Many individuals with obesity report profound body dissatisfaction as a primary motivation for bariatric surgery, sometimes outweighing health-related reasons Body schema mechanisms have not yet been directly investigated in bariatric populations, despite potential relevance to post-operative body representation adaptation
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
This review identifies body schema updating as a potentially overlooked mechanism in post-bariatric surgery adaptation. Clinicians should recognize that persistent body misperception after surgery may reflect neural representation lag rather than solely psychological body dissatisfaction, but direct evidence is lacking and empirical investigation is needed before clinical application.
This is a narrative review proposing a theoretical mechanism (body schema updating) for post-bariatric surgery body image disturbance, explicitly acknowledging the absence of direct empirical evidence in the target population.

What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
As indicated by the guidelines of the National Institutes of Health (NIH) and the Italian Society of Obesity Surgery and Metabolic Diseases (SICOB), bariatric surgery is the treatment of choice for severe obesity due to its effectiveness in achieving long-term weight loss and improving associated comorbidities. Many individuals with obesity exhibit profound body dissatisfaction, which often represents a primary motivation for seeking bariatric surgery, sometimes outweighing health-related reasons. Following surgery, a significant reduction in body weight is typically observed; however, perceived body image does not always change in parallel with physical transformation. Some individuals experience difficulties adapting to bodily changes, with a persistent perception of themselves as people with obesity despite substantial weight loss. This phenomenon is typically interpreted in terms of body image disturbances; however, it may also indirectly point to difficulties in updating body representations, potentially involving body schema mechanisms, although this has not yet been directly investigated in bariatric populations. Given the limited number of studies on body schema in this context, this article provides a narrative and theory-driven review of body representation following bariatric surgery. Specifically, it integrates findings from body image research, obesity studies, and embodied cognition to explore whether body schema updating may contribute to the mismatch between physical and perceived body. This interpretation remains hypothetical and highlights a critical gap in the literature, namely the lack of direct empirical investigations of body schema in bariatric populations. Further research is needed to clarify its role in post-operative adaptation and its implications for psychological and behavioural outcomes.
