Obesity and metabolic (bariatric) surgery

Surgical treatment of severely obese adolescents with type 2 diabetes is associated with better glycemic control and a greater reduction in BMI than medical management, US researchers report.

Obese patients who undergo bariatric surgery are significantly less likely to require treatment for diabetes 6 years post-surgery compared with those who do not undergo such procedures, study findings indicate.

The 5-year outcomes of the Diabetes Surgery Study show that the benefits of gastric bypass remain but are of smaller magnitude compared with the 1-year results.

Obese patients who undergo bariatric surgery are more likely to self-harm or die by suicide than those who undergo nonsurgical management, but the absolute risk is low, suggests an analysis of two Scandinavian cohorts.

Research shows that patients who undergo Roux-en-Y gastric bypass are extremely unlikely to develop diabetes over the following decade, and a large proportion of those who have the condition at the time of surgery achieve remission.

The all-cause mortality benefits of Roux-en-Y gastric bypass surgery are predominantly driven by patients who have diabetes at the time of surgery, according to the results of an observational study.

A study suggests that obese patients may improve their chances of becoming non-obese and reversing comorbidities such as diabetes if they undergo bariatric surgery before their body mass index reaches 40 kg/m².

The 24th European Congress on Obesity is taking place this week in Porto, Portugal, with key presentations including the findings from the World Health Organization’s Health Behaviour in School-aged Children survey.

Research shows that the largest long-term reductions in microvascular complications around 20 years after bariatric surgery for obesity are seen among patients who had prediabetes at the time of surgery.

Long-term follow-up of the STAMPEDE trial shows that improvements in body mass index and glycemic control are maintained 5 years after metabolic surgery in patients with type 2 diabetes.

Two studies of patients who underwent bariatric surgery during adolescence reveal sustained weight loss and improved cardiovascular risk factors 5 years or more after the procedure.

Closed-loop gastric electrical stimulation is noninferior to adjustable gastric band for weight loss and has markedly fewer adverse effects, show the 1-year findings of a randomised trial.
