Semaglutide is an injectable medication approved for weight loss in addition to its use for type 2 diabetes management. As a GLP-1 receptor agonist, it works by increasing feelings of fullness, reducing appetite, and slowing gastric emptying. Clinical studies have shown that it can lead to significant weight loss when combined with a reduced-calorie diet and increased physical activity, making it a valuable option for individuals looking to achieve and maintain weight loss.
