If you've recently started taking Wegovy (semaglutide) for weight loss, you may be curious about how long Wegovy stays in your system. This once-weekly injectable medication has gained widespread popularity for its impressive weight loss results.

What Is Wegovy?

Wegovy is a glucagon-like peptide-1 (GLP-1) receptor agonist that works by mimicking the effects of the naturally occurring hormone GLP-1. When injected, the medication is gradually absorbed into the bloodstream and distributed throughout the body. 

Wegovy binds to GLP-1 receptors in the brain and gut. This mechanism decreases appetite and promotes feelings of fullness, slows down gastric emptying, and improves blood sugar regulation. 

Together, these actions lead to reduced calorie intake and improved metabolic function. Clinical trials have shown up to 15% reduction of their initial body weight on the highest dose when combined with lifestyle changes. 

Its unique mechanism makes it a powerful tool for sustainable weight management.
