Semaglutide for Weight Loss: A Complete Guide to This Game-Changing Drug

 *Introduction*

*Semaglutide* is a revolutionary medication originally developed to manage *type 2 diabetes*, but it has now gained worldwide attention for its *dramatic effects on weight loss*. It belongs to the *GLP-1 receptor agonist* class and is available under brand names like *Ozempic*, *Wegovy*, and *Rybelsus*.

In 2021, the *FDA approved Wegovy (semaglutide 2.4 mg weekly)* specifically for *chronic weight management*, making it the first drug of its kind in years to show such significant results.
