Introduction Bariatric surgery is an evidence-based approach for sustained weight loss in patients with severe obesity. The most common procedures in North America are the laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). The Edmonton Obesity Staging System (EOSS) is a tool that assigns patients a score of 0 t...

Background Accumulating evidence suggests that the metabolic effects of metformin and fermentable fibers are mediated, in part, through diverging or overlapping effects on the composition and metabolic functions of the gut microbiome. Pre-clinical animal models have established that the addition of fiber to metformin monotherapy improves glucose to...

Obesity is a prevalent, complex, progressive and relapsing chronic disease, characterized by abnormal or excessive body fat (adiposity), that impairs health. People living with obesity face substantial bias and stigma, which contribute to increased morbidity and mortality independent of weight or body mass index. This guideline update reflects su...

Background The Edmonton Obesity Staging System (EOSS) is a staging system describing comorbidities and functional limitations associated with obesity, thus facilitating the prioritization of patients for bariatric surgery. Our objective was to elucidate any associations of EOSS scores with major complications after laparoscopic Roux-en-Y gastric by...
Article
We assessed the value of the Edmonton Obesity Staging System (EOSS) compared with the body mass index (BMI) for determining associations with use of health services and pharmacotherapies in a nationally representative sample of participants in the 2011–2013 Australian Health Survey. A subsample of participants aged 18 years or over, with at least o...

Obesity is a stigmatized disease due to pervasive personal, professional, institutional, and cultural weight bias. Individuals with obesity experience weight bias across their lifespan and settings, which can affect their life chances and significantly impact health and social outcomes. The objectives of this study were to: (a) explore weight bias...
