Core Tip
Core Tip: Obesity and diabetes are growing at an alarming rate. Bariatric surgery is an effective method for weight management and inducing diabetes remission (DR); therefore, choosing the correct type of bariatric surgery is important. Sleeve gastrectomy is the most frequently performed bariatric surgery, and one-anastomosis gastric bypass has seen an increase in popularity recently. Literature regarding the most effective bariatric surgery for weight reduction and DR is scarce. This review provides broader insights into one-anastomosis gastric bypass and sleeve gastrectomy in the medium term, including their impact on excess weight loss, DR, complications, mortality, and quality of life.
