Obesity and type 2 diabetes mellitus have been associated with higher morbidity and mortality. Bariatric surgery results in substantial and sustained weight loss in morbidly obese patients and improves obstructive sleep apnea. Furthermore, bariatric surgery improves diabetes control, hypertension, quality of life, stroke, myocardial infarction and reduces mortality. Interestingly, bariatric surgery induces high rates of short and long-term diabetes remission. While the exact mechanisms behind this are not completely understood, improved insulin action, β-cell function and a complex interplay of hormones in the entero-insular axis appear to play major roles. Insulin action improves proportionally to weight loss and it gets completely normalized especially after bilio-pancreatic diversion. β-Cell function also seems to improve after a variety of bariatric surgeries. Seemingly, baseline β-cell function is able to predict future diabetes remission. This article will review the effectiveness of bariatric procedures on the remission and improvement of diabetes and its implicated mechanisms.

Expert Rev Gastroenterol Hepatol
January 2025
Department of Surgery, Trinity St. James's Cancer Institute, Dublin, Ireland.
Introduction: Advances in treatment strategies for gastric and esophageal cancer have led to improved long-term outcomes, however the local and systemic effects of tumor growth, neoadjuvant therapies and surgery, results in specific nutritional challenges. Comprehensive nutritional evaluation and support represents a core component of multidisciplinary holistic care for this patient population.
Areas Covered: This review provides a detailed overview of the nutritional challenges in gastric and esophageal cancer, with a focus on malignant obstruction, preoperative optimization and nutrition in survivorship.
Semaglutide and laparoscopic sleeve gastrectomy in an adolescent with congenital adrenal hyperplasia due to 21-hydroxylase: a case report.

Background: Classic congenital adrenal hyperplasia, primarily due to 21-hydroxylase deficiency, leads to impaired cortisol and aldosterone production and excess adrenal androgens. Lifelong glucocorticoid therapy is required, often necessitating supraphysiological doses in youth to manage androgen excess and growth acceleration. These patients experience higher obesity rates, hypertension, and glucose metabolism issues, complicating long-term health management.

Background: Metabolic and bariatric surgery (MBS) is a suitable solution for the treatment of morbid obesity. Investigating an MBS method that has the best outcomes has always been the main concern of physicians. The current study aimed to compare nutritional, anthropometric, and psychological complications of individuals undergoing various MBS Techniques.

Background: Earlier evidence indicated that metabolic and bariatric surgery (MBS) may adversely affect neonatal outcomes among patients conceiving soon after MBS, but recent studies demonstrated conflicting results, especially for new surgical techniques.
Objectives: The aim of this study was to assess the effects of MBS types and surgery to birth interval on maternal, birth, and nonbirth outcomes in women with severe obesity.
Setting: New York State's all-payer hospital discharge database (2008-2019).
Background: Transumbilical single-port sleeve gastrectomy (SPSG) is a minimally invasive bariatric surgery that offers cosmetic benefits. However, the procedure's feasibility in patients with higher BMI or taller stature remains debated. This study evaluates the outcomes of SPSG based on patient height and BMI.
