Bariatric surgery comprises operative procedures that treat severe obesity by altering the gastrointestinal tract to reduce intake, modify nutrient absorption, and influence gut-hormone signalling that affects appetite and metabolism. Common approaches include sleeve gastrectomy and Roux-en-Y gastric bypass, alongside endoscopic and device-based options such as intragastric balloons, and they are generally indicated for individuals with severe obesity who have not achieved durable weight loss through diet, physical activity, and behavioural means. Beyond weight reduction, these interventions can improve obesity-related metabolic disease, but they require careful patient selection and long-term nutritional and clinical follow-up. Research in this area examines outcomes and complications, including sequential intragastric balloon treatment in super-obesity, predictive markers for lower-quartile weight loss after gastric bypass, and the nutritional consequences of surgery, such as deficiencies in pregnancy after obesity surgery and Wernicke encephalopathy following sleeve gastrectomy. Studies situate surgery within the wider management of obesity, addressing dietary regimens for reversal of obesity, body-composition modelling that links severe obesity to skeletal-muscle mass, energy-expenditure estimation, obesity in psychiatric populations, and related comorbidities including obstructive sleep apnea. By connecting surgical, nutritional, and metabolic perspectives, the field informs safe and effective management of severe obesity. The journal publishes peer-reviewed research relevant to bariatric surgery and the broader clinical care of obesity.
