How This Works
Semaglutide is a GLP-1 receptor agonist with 94% sequence homology to native human GLP-1[4]. It promotes weight loss through multiple mechanisms: reducing appetite and food intake via central nervous system effects, slowing gastric emptying, and improving glycemic control through glucose-dependent insulin secretion[1][3]. The extended half-life of approximately 7 days is due to albumin binding and resistance to DPP-4 degradation, enabling convenient once-weekly measurement[1]. Clinical trials have demonstrated significant weight loss (mean 10–15% body weight reduction) in individuals with obesity when combined with lifestyle interventions[1][5]. The weekly 2.4 mg maintenance dose is FDA-approved for chronic weight management and represents the standard clinical approach[3][4].
