Background
This study investigates preoperative patient expectations of metabolic bariatric surgery (MBS), focusing on anticipated challenges and effects on physical, social, and psychological domains.
Methods
A prospective, cross-sectional multicenter survey among adult patients awaiting primary MBS was conducted. The questionnaire gathered data on (1) the top three reasons for seeking surgery, (2) anticipated weight loss, and (3) expected remission of obesity-related diseases. Patients also rated the importance of being informed about potential complications, anxiety over complications, and the extent to which these complications influence their decision to undergo surgery. Additionally, patients reported their expectations of physical, social, and psychological changes.
Results
A total of 242 patients completed the questionnaire. Patients prioritized mobility and health as the main reasons for choosing MBS, with other key factors including pain reduction, remission of obesity-related diseases, and physical fitness. Patients expected a median percentage total weight loss of 32% and a percentage excess weight loss of 81%. Most patients expected total remission of obesity-related diseases. Although patients valued information on potential complications, these risks did not induce anxiety or affect the decision to undergo MBS. The most anticipated physical changes included improved mobility, pain reduction, and better health/fitness. The most expected social and psychological changes were related to self-image and emotional well-being.
Conclusions
Improved mobility and health were the main reasons for undergoing MBS. Although participants had high weight loss expectations, their estimations for obesity-related diseases resolutions were accurate. Despite prioritizing information about potential complications, this did not discourage patients from choosing MBS.
