1. Stimulates Insulin Secretion
Semaglutide enhances the release of insulin from the pancreas in response to elevated blood glucose levels.
This helps lower blood sugar after meals (postprandial glucose).
2. Suppresses Glucagon Release
It reduces the secretion of glucagon, a hormone that increases blood sugar levels.
This action prevents the liver from releasing excessive glucose into the bloodstream.
3. Slows Gastric Emptying
Semaglutide delays the emptying of the stomach, which helps to reduce the speed at which glucose enters the bloodstream.
This contributes to better blood sugar control and may help with appetite suppression.
4. Promotes Satiety
By acting on the appetite-regulation centers in the brain, semaglutide helps reduce hunger and calorie intake.
This effect supports weight loss in individuals with obesity or overweight.
5. Improves Beta-Cell Function
Semaglutide enhances the function and survival of pancreatic beta cells, which are responsible for insulin production.
