Ghost Fat: Altered Female Body Perception After Bariatric Surgery

Area of Science:

• Psychology
• Bariatric Surgery Research
• Body Image Studies

Background:

• Body perception encompasses attitudinal and dimensional aspects of self-recognition.
• Bariatric surgery leads to significant weight loss, potentially impacting body perception.
• Understanding post-surgical body image is crucial for patient well-being.

Purpose of the Study:

• To investigate changes in women's attitudinal body image (ABI) and dimensional body image (DBI) before and after bariatric surgery.
• To assess the impact of rapid weight loss on body perception.
• To identify potential persistent distortions in body awareness post-surgery.

Main Methods:

• Longitudinal study of 31 women undergoing bariatric surgery.
• Collection of anthropometric data and body perception measures (ABI and DBI) at multiple time points pre- and post-surgery (up to 120 days).
• Analysis of body weight changes and statistical comparison of ABI and DBI scores.

Main Results:

• Participants experienced an average body weight decrease of 21.09% within 120 days.
• Attitudinal body image significantly improved, with body dissatisfaction dropping from 51.61% pre-surgery to 3.23% at 120 days post-surgery.
• No statistically significant changes were observed in dimensional body image, with some participants reporting a "ghost fat" sensation.

Conclusions:

• Bariatric surgery effectively enhances attitudinal body image and reduces body dissatisfaction.
• Dimensional body image perception remains distorted post-bariatric surgery, potentially due to rapid weight loss.
• Somatosensory interventions or extended follow-up may be necessary to address persistent body dimension misperceptions.
