Psychological Well-Being and Weight Loss After Bariatric Surgery in Patients With and Without Chronic Pain

Overview

This study compared psychological outcomes and weight loss following bariatric metabolic surgery in patients with obesity, stratified by presence or absence of chronic pain conditions. Both groups achieved significant weight loss and improvements in depressive symptoms, quality of life, self-esteem, and self-efficacy measures over 24 months. Patients with chronic pain experienced comparable psychological benefits to those without pain, despite baseline differences.

Background

Obesity and chronic pain are closely linked, with up to 40% of adults with obesity experiencing chronic pain, which often includes musculoskeletal pain, fibromyalgia, and other syndromes. Chronic pain exacerbates physical inactivity, depressive symptoms, and poor quality of life in this population. Bariatric metabolic surgery is effective for substantial weight loss and improvement of obesity-related comorbidities, including pain. However, the differential psychological impact of surgery in patients with versus without chronic pain has not been well studied. This study aimed to evaluate whether patients with chronic pain experience greater psychological improvements post-surgery compared to those without pain.

Data Highlights

Key Findings

• Both patients with and without chronic pain achieved significant and comparable weight loss 24 months after bariatric surgery.
• Depressive symptoms decreased substantially in both groups, indicating improved psychological well-being.
• Health-related quality of life and self-esteem improved similarly regardless of chronic pain status.
• Self-efficacy for exercise and actual physical activity increased postoperatively in both groups.
• Patients with chronic pain did not experience greater psychological improvements than those without pain, contrary to the initial hypothesis.
• Chronic pain presence did not negatively affect the psychological benefits derived from bariatric surgery.

Clinical Implications

Clinicians can expect that bariatric metabolic surgery will yield significant psychological and functional benefits in patients with obesity, irrespective of chronic pain status. The presence of chronic pain should not be considered a barrier to achieving improvements in depressive symptoms, quality of life, or self-efficacy post-surgery. Comprehensive preoperative assessment and postoperative support remain essential to optimize outcomes for all patients.

Conclusion

Bariatric metabolic surgery leads to substantial weight loss and psychological improvements in patients with obesity, with or without chronic pain conditions. Chronic pain does not diminish the positive effects of surgery on psychological well-being and functioning over a 24-month follow-up.
