Bariatric surgery, specifically Roux-en-Y gastric bypass (RYGB), improves metabolic health partly by activating the endocannabinoid system (CB-1) to increase sympathetic nerve activity and promote white adipose tissue browning.

If you are considering bariatric surgery, understand that it works by changing how your body signals hunger and burns energy, not just by restricting food intake. Discuss all options with your healthcare provider.

the beneficial metabolic effects of Roux-en-Y gastric bypass (RYGB) surgery in diet-induced obese mice are partly attributable to increased activity of the splanchnic nerve (a part of the SNS) by activation of CB-1 which result in visceral WAT (vWAT) browning, enhanced visceral thermogenesis and increased resting metabolic rate
