What is Wegovy (Semaglutide)?
Wegovy is a breakthrough weight loss medication that has helped millions of people manage their weight effectively.
Overview
Wegovy contains the active ingredient semaglutide. It is a GLP-1 receptor agonist that was specifically approved for weight management in 2021.
It is a weekly injection, similar to Mounjaro, and comes in pre-filled pens.
How Does It Work?
Wegovy mimics the hormone GLP-1 (glucagon-like peptide-1) that targets areas of the brain that regulate appetite and food intake.
By increasing feelings of fullness and reducing hunger, it helps you eat fewer calories and lose weight.
How Effective Is It?
In clinical trials (STEP trials), participants taking Wegovy lost an average of 15% of their body weight over 68 weeks.
More than one-third of participants lost more than 20% of their body weight.
