Semaglutide is a medication originally developed for managing type 2 diabetes, now widely used for weight loss. It is a glucagon-like peptide-1 (GLP-1) receptor agonist that works by enhancing insulin secretion, reducing appetite, and slowing gastric emptying. Clinical trials have demonstrated significant weight loss in individuals taking semaglutide, making it a popular option for obesity treatment. Administered via subcutaneous injection, typically once a week, semaglutide supports sustainable weight management by helping individuals reduce caloric intake and improve metabolic health.
