Clinical Report: Patient Expectations and Concerns Before Bariatric Surgery

Overview

This study surveyed patients awaiting metabolic bariatric surgery (MBS) to assess their motivations, expectations, and concerns regarding both short- and long-term outcomes. Findings reveal that while weight loss and improvement of obesity-related diseases remain primary motivations, patients also anticipate psychological and social benefits, yet often hold unrealistic weight loss expectations and have varying concerns about postoperative complications.

Background

Metabolic bariatric surgery is an effective treatment for severe obesity, primarily targeting weight loss and improvement of obesity-related diseases. Recent research emphasizes the importance of quality of life outcomes, including mental health and social functioning, beyond physical health improvements. Patients seek MBS for diverse reasons, including fertility, pain reduction, and emotional well-being, but often have high and sometimes unrealistic expectations for weight loss. Understanding patients’ preoperative expectations and concerns is crucial for optimizing counseling and managing postoperative satisfaction.

Data Highlights

Patients reported expected excess weight loss (%EWL) between 71% and 94%, exceeding the long-term weighted mean %EWL of 57% reported in literature. The study assessed patient concerns about short-term (≤30 days) and long-term (>2 years) complications using 5-point Likert scales across domains of information importance, anxiety, and impact on surgery consideration. Subgroup analyses evaluated differences by gender, BMI, age, and presence of obesity-related diseases.

Key Findings

• Primary motivations for MBS include weight loss and improvement of obesity-related diseases, with additional goals such as enhanced fertility, pain reduction, and improved social and emotional well-being.
• Patients often have unrealistic weight loss expectations, anticipating %EWL between 71% and 94%, higher than the typical long-term clinical outcome of approximately 57%.
• Psychological benefits, such as improved self-esteem, are significant postoperative sources of satisfaction, sometimes surpassing initial weight loss motivations.
• Patients accept substantial risks of short-term complications and mortality to achieve weight loss goals, with higher BMI patients willing to accept greater risks.
• There is limited prior exploration of patients’ concerns about long-term postoperative challenges, which this study aims to address.
• Preoperative counseling should incorporate discussions about realistic weight loss outcomes and potential long-term complications to better manage patient expectations.

Clinical Implications

Clinicians should provide comprehensive preoperative counseling that addresses not only physical outcomes but also psychological and social expectations of MBS. Managing unrealistic weight loss expectations and discussing potential short- and long-term complications can improve patient satisfaction and adherence to postoperative care. Tailoring information based on patient characteristics such as BMI and age may further optimize shared decision-making.

Conclusion

Understanding patients’ multifaceted expectations and concerns before bariatric surgery is essential for effective counseling and improving long-term satisfaction. Addressing both physical and psychosocial domains preoperatively can help align patient goals with realistic outcomes.
