What is Semaglutide?

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist that mimics the GLP-1 hormone released in the gastrointestinal tract in response to eating. It works by increasing insulin secretion, decreasing glucagon secretion, and slowing gastric emptying. Originally developed for type 2 diabetes management, semaglutide has gained significant attention for its effectiveness in weight loss. The medication helps reduce appetite and food intake, leading to substantial weight reduction when combined with diet and exercise.
