Evaluating the Efficacy of Neurofeedback in Post-Bariatric Surgery Patients: A Pilot Study

<b>Background</b>: Obesity remains a major global health challenge, and a significant proportion of bariatric surgery patients continue to experience dysfunctional emotional eating and body image concerns after surgery. Neurofeedback training (NFT) has been investigated as a potential intervention for maladaptive eating behaviours, but evidence in post-bariatric populations is still limited. <b>Methods</b>: Thirty-six patients who underwent sleeve gastrectomy were included, divided into an NFT group (N = 18) and a control group (N = 18). Assessments were performed at baseline and after 10 NFT sessions, using the Eating Disorder Inventory (EDI) and the Body Uneasiness Test (BUT). The intervention aimed to enhance alpha and theta waves with real-time feedback. <b>Results</b>: Compared with the control group, the NFT group showed significant improvements; specifically, reductions were observed in EDI subscales such as Drive for Thinness (<i>p</i> = 0.023, d = 0.51), Bulimia (<i>p</i> = 0.008, d = 0.92), Body Dissatisfaction (<i>p</i> = 0.015, d = 0.52), Ineffectiveness (<i>p</i> = 0.002, d = 0.89), Perfectionism (<i>p</i> = 0.006, d = 0.70), Interpersonal Distrust (<i>p</i> = 0.008, d = 0.82), and Interoceptive Awareness (<i>p</i> = 0.001, d = 0.91). Significant reductions were also found in BUT subscales including Weight Phobia (<i>p</i> = 0.041, d = 0.84), Body Image Concern (<i>p</i> = 0.039, d = 0.90), Avoidance (<i>p</i> = 0.027, d = 0.83), Compulsive Self-Monitoring (<i>p</i> = 0.013, d = 0.83), and Depersonalisation (<i>p</i> = 0.033, d = 0.85). <b>Conclusions</b>: The data indicate that NFT may help reduce emotional eating and related psychological factors in post-bariatric patients in the short term. However, studies with larger samples and longer follow-ups are needed to confirm its effectiveness and assess its clinical applicability.
