Semaglutide & Tirzepatide
Semaglutide and tirzepatide are prescription medications used to support weight loss by helping regulate appetite and food intake. They work by mimicking natural hormones that signal fullness and slow down digestion, making it easier to eat less and feel satisfied longer. Tirzepatide targets two appetite-related hormones for a stronger effect, while semaglutide targets one. When combined with healthy habits, both medications have been shown to help people achieve significant and sustained weight loss.
