Abstract
Obesity is a globally prevalent condition associated with elevated morbidity and mortality. Metabolic and bariatric surgery offers a definitive treatment for class III (BMI > 40) obesity, achieving substantial, enduring weight loss and improving metabolic health. Despite extensive research on the physical benefits, comparatively fewer reviews investigate the psychosocial and relational changes accompanying these procedures. This narrative review examines how such procedures affect partner relationship quality, sexual function, and broader social integration, aiming to synthesise current findings on key factors like self-esteem, body image, and family support in the recovery process. It further discusses how strong social networks can bolster long-term weight management and psychological outcomes. By viewing these multifaceted changes through a holistic, family-centred lens, the review highlights the interdependence of emotional, familial, and community support systems in optimizing postoperative results and sustaining improvements in quality of life.
