Ozempic (semaglutide) works by mimicking a natural hormone in the body called GLP-1 (glucagon-like peptide-1), which helps regulate appetite, slow digestion, and balance blood sugar levels. By activating GLP-1 receptors in the brain and gut, it reduces hunger and cravings, helps you feel full longer, improves insulin sensitivity, and supports healthy glucose metabolism. The result is a science-backed, sustainable approach to weight management that works with your body’s own biology — promoting steady weight loss without strict dieting or exercise.
