Hormonal

Bariatric surgery (RYGB/VSG) provides superior sustained weight loss (13-27%) and T2D remission compared to pharmacological interventions, largely driven by endocrine changes rather than just mechanical restriction.

Bariatric surgery (like gastric bypass) is currently the most effective treatment for obesity, achieving 13-27% sustained weight loss and often curing type 2 diabetes. Its success is driven by hormonal changes (increased GLP-1/PYY) rather than just stomach size reduction. However, due to its invasive nature, it is reserved for extreme cases, driving the need for drugs that can mimic these hormonal effects.

StrongSupportsVERY_HIGH confidence
Bariatric surgery is rapidly gaining in popularity, and large-scale follow-up studies dependent on the surgical procedure, demonstrating sustained weight loss of 13%–27%, with follow-up for as much as 15 years... The improvement of metabolic control cannot be singularly justified by the physical limitation in gastrointestinal uptake of food, and notably glucose metabolism is typically improved much before a meaningful decrease in body weight is observed.
