After weight-loss surgery, the gut becomes more responsive to bile acids via a receptor called TGR5, which helps trigger the release of a hormone (GLP-1) that improves blood sugar control.

Similar Assertions

After metabolic or bariatric surgery, people experience a doubling of GLP-1 hormone levels following meals, unlike those who lose the same amount of weight through dieting. This higher hormone level is linked to feeling fuller after eating.

If someone has had weight-loss surgery but didn’t lose enough weight or gained it back, taking GLP-1 drugs (like Ozempic or Wegovy) can help them lose about 7.8 kilograms (around 17 pounds) on average, with better results the longer they stay on the medication.
