Semaglutide is a medication that belongs to the class of GLP-1 receptor agonists. It works by mimicking the action of a natural hormone called glucagon-like peptide-1 (GLP-1), which helps regulate appetite and metabolism. When used for weight management, semaglutide can reduce hunger, make you feel fuller, and slow down the emptying of your stomach, leading to a decreased calorie intake. This medication is usually administered as a once-weekly injection and has shown promising results in helping individuals achieve significant weight loss when combined with a healthy diet and exercise program.
