Special Issue Information
Dear Colleagues,
Obesity, largely driven by lifestyle changes over recent decades, is now a major global health concern. It is strongly linked to comorbidities such as type 2 diabetes, cardiovascular disease, hypertension, and certain cancers, all of which contribute to reduced life expectancy. Traditional strategies including diet, exercise, and pharmacological treatments remain first-line approaches but often fail to achieve significant or lasting weight reduction in severe obesity, with frequent relapses and weight regained.
Bariatric surgery (BS) has become the most effective therapeutic option for individuals with morbid obesity. Procedures such as gastric bypass and sleeve gastrectomy induce substantial and sustained weight loss, offering a superior benefit–risk ratio compared with nonsurgical methods. Beyond weight reduction, BS improves metabolic parameters, frequently achieves diabetes remission, reduces cardiovascular risks, and enhances both quality of life and psychological well-being. On average, BS extends life expectancy by more than six years compared with conventional therapy.
Optimal outcomes depend on specialized nutritional management before and after surgery to prevent deficiencies and long-term complications. This includes assessing levels of key nutrients and correcting deficits via targeted supplementation or dietary adjustments. The role of preoperative weight loss remains debated: it may ease surgery and reduce risks but can delay treatment. Correcting nutritional status preoperatively appears beneficial, improving both immediate and long-term outcomes by ensuring that the body has adequate reserves for surgical recovery.
This Special Issue will showcase cutting-edge research on preoperative and postoperative nutritional management in bariatric surgery, with a focus on strategies to optimize nutrient balance, prevent deficiencies, and support long-term weight maintenance and metabolic improvement. We welcome original research and review articles that explore evidence-based nutritional assessments, personalized dietary interventions, supplementation protocols, and the impact of nutritional care on surgical outcomes in patients undergoing bariatric surgery.
