Gastric bypass results in large and long-lasting weight loss (25-27% total body weight loss at 12-15 years) and remission of obesity-related conditions, making it suitable for patients with BMI 35-50 kg/m2, especially with type 2 diabetes or reflux.
Gastric bypass is a highly effective surgical option for patients with BMI 35-50, especially those with type 2 diabetes or reflux. It leads to large, long-lasting weight loss (25-27% at 12-15 years) and remission of obesity-related conditions.

Gastric bypass results in large and long-lasting weight loss. Maximum weight loss is achieved at 2 years (30%–35% reduction of total body weight), and at 12–15 years postoperatively, a 25%–27% total body weight loss remains [49, 50].

More from this paper
- Lifestyle treatment alone has modest or little long-term effect on weight loss, particularly in adults, and is often insufficient for sustainable weight maintenance due to biological drivers like hunger.Strong
- Semaglutide (GLP-1 receptor agonist) produces significant weight loss (15.5% in adolescents, 12.5% in adults) and cardiovascular benefits, making it a prioritized treatment for those with metabolic risk factors.Good
- Phenotype-guided pharmacotherapy (matching 'hungry gut' to GLP-1, 'hungry brain' to phentermine-topiramate, and 'slow burn' to phentermine + resistance training) yields 1.75-fold greater weight loss compared to non-phenotype-guided treatment.Moderate

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
