Obesity is a complex chronic disease, and while metabolic and bariatric surgery (MBS) remains the most effective treatment for weight loss, results vary widely among patients. The surgery often leads to improvement or remission of related health conditions, but concerns about negative psychosocial effects persist.
Research suggests that psychological evaluations before MBS are valuable for both patients and medical teams. These evaluations help identify potential risks and are linked to postoperative challenges. Experts recommend that a trained clinician conduct these assessments as a standard part of care, benefiting all involved.
Improving current research and clinical practices could strengthen the connection between psychological factors and surgical outcomes. Studies should rely on structured clinical interviews rather than less reliable methods such as unstructured assessments or chart reviews. Behavioral health professionals are encouraged to use rigorous, evidence-based tools and combine multiple sources of information when possible.
Instead of viewing mental health in rigid categories, clinicians and researchers should consider a more flexible, symptom-based approach. Recognizing that symptoms often overlap and that personality traits like impulsivity and negative emotions may better predict outcomes can improve understanding and treatment.
Evaluations should also look beyond short-term weight loss and early complications. Long-term issues such as nutrient deficiencies, behavioral problems like alcohol use, and weight regain after six months are critical concerns for MBS patients. Factors such as quality of life, social functioning, improvement in medical conditions, economic impact, and lifespan should be included in outcome assessments.
Psychological testing is an important part of pre-surgical evaluations and can help predict patient outcomes. These tests can also detect response styles, such as underreporting symptoms, which assist clinicians in better understanding patients. Continued insurance coverage for psychological testing and thorough evaluations is necessary.
Preoperative psychological evaluations are more comprehensive than routine diagnostic assessments. They aim to identify risks related to surgery and work with patients and surgical teams to reduce these risks before and after the procedure. Just as medical clearance is required to ensure physical readiness for surgery, behavioral health experts play a vital role in assessing and managing psychosocial risks.
Currently, pre-surgical psychological evaluations remain essential for MBS candidates. However, research needs to explore their impact on broader outcomes beyond weight loss. While researchers can adjust methods to improve studies, clinicians face practical challenges such as increased time demands and costs, which may affect patient access and reimbursement.
Future research should address these logistical and financial challenges. It should also include patient-centered measures such as satisfaction with behavioral health services and the views of multidisciplinary MBS teams on the usefulness of comprehensive psychological evaluations.
