Semaglutide, under the brand name Wegovy, can be used for weight loss. You’ll need to meet the criteria to take it, such as having a BMI of overweight (27 to 30) and a weight-related medical condition like prediabetes, or a BMI of obese (30 or more).
Wegovy comes as an injection. Research has shown that people lose up to 21% of their starting weight after taking 7.2mg a week for 72 weeks.
How does semaglutide work for weight loss?
Semaglutide works by binding to GLP-1 receptors and mimicking the actions of the natural hormone GLP-1. This means it sends signals to your brain, reducing your appetite and causing the stomach to empty more slowly, making you feel less hungry and fuller for longer.
Naturally, GLP-1 only does this after eating, but semaglutide taken once a week will continuously reduce your appetite, so you’ll feel less hungry all the time, not just after eating. It works effectively alongside a diet and exercise plan.
How do you take semaglutide for weight loss?
