Research presented at this year’s European Congress on Obesity (ECO 2026, Istanbul, Turkey, 12-15 May) shows that those living with obstructive sleep apnoea (OSA) have a 71% higher risk of cardiovascular events (CVEs) or death from any cause (all-cause mortality) compared with those not living with OSA. OSA is characterised by recurrent upper airway obstruction during sleep and is associated with reduced quality of sleep and life and increased cardiovascular risk. The preval

A global panel of 21 obesity and cancer experts have suggested that to test the potential efficacy of the new generation of obesity drugs such as semaglutide and tirzepatide in preventing obesity-related cancer (ORC), a trial of the drugs for some 5,000 participants at high risk of cancer due to their having a cancer pre-cursor condition will provide the required answers. The group of experts, convened at the European Congress on Obesity (ECO2026) in Istanbul, Turkey, includi

Research from Italy presented at this year's European Congress on Obesity, Istanbul, Türkiye, shows that when the gold standard technique of dual-energy X-ray absorptiometry (DXA) is used to measure body fat in the general population, it shows that the traditional WHO body mass index (BMI) classification system misidentifies significant numbers of people as having overweight or obesity. In the past few years there has been a lot of criticism of the BMI system due to its inabi

Prediabetes may leave a lasting molecular "footprint" on adipose (fat) tissue which appears to make maintaining weight loss after bariatric surgery more difficult, according to new research being presented at the European Congress on Obesity (ECO) in Istanbul, Turkey. "Our findings suggest that prediabetes is associated with persistent changes in fat tissue that may limit its ability to fully adapt after weight loss," said author, Dr Camila Milad from Hospital Clinic de Barce

Adults with overweight or obesity taking the new generation of weight loss drugs semaglutide and tirzepatide tend to eat significantly less, leaving them vulnerable to nutritional deficiencies, according to one of the first real-world studies to examine dietary behaviour in people using glucagon-like peptide-1 receptor agonists and dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) dual agonists RAs (collectively referred to as GLP-1 RAs) with the help of an AI-pow

Johnson & Johnson has announced results from the first clinical study of the investigational OTTAVA Robotic Surgical System – a prospective, multi-centre clinical study evaluating the safety and performance of the system in Roux-en-Y gastric bypass (RYGB) procedures. The results were presented at the 2026 American Society for Metabolic and Bariatric Surgery (ASMBS) Annual Meeting. “The data show encouraging evidence regarding the safety and performance of the OTTAVA™ Robotic

Bariatric News spoke with Professor Paulina Salminen, a professor of surgery and gastrointestinal surgery at University of Turku and Turku University Hospital in Finland, and President of the European Chapter of the International Federation For Surgery and Other Therapies for Obesity (IFSO-EC/IFSO), about her career path, her commitment to evidence-based research, and the challenges facing metabolic and bariatric surgery (MBS)... Why did you decide to enter medicine? Initial

For nearly two decades, Professor Michel Gagner (Professor of Surgery in Montreal, Canada) has been working on new technologies to eliminate the limitations and complications associated with staplers and sutures. His innovative solution is magnetic compression anastomosis. In this interview he discusses the evolution of the technology, the positive outcomes, the latest data to be presented in Malaga and why he believes it could revolutionise the future if gastro-intestinal (G

The British Obesity & Metabolic Specialist Society (BOMSS) recently revealed that endoscopic sleeve gastroplasty (ESG) procedural data will be incorporated into the Society’s National Bariatric Surgery Registry (NBSR). In this interview, Mr Omar Khan, Chair of the NBSR Committee, and Mr Jamie Kelly, who has performed over 500 ESG procedures, discuss the importance of the registry, why ESG plays a crucial role in the armamentarium of a bariatric specialist and the future possi

More than one billion people worldwide are living with obesity. Lifestyle intervention programmes, GLP-1 medications and bariatric surgery can be transformative, but they do not exist in a nutritional vacuum. Deficiencies are common among people affected by obesity before treatment begins, and surgery or medication can make them harder to ignore. Patients arrive underprepared, find little nutritional support built into their care, and are largely left to manage the consequenc
