*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.
*Mechanism of Action*
Semaglutide mimics *GLP-1 (glucagon-like peptide-1)* — a hormone that:
- *Slows gastric emptying*, making you feel full longer
- *Reduces appetite and food intake*
- *Increases insulin secretion*
- *Decreases glucagon release*
By acting on appetite centers in the *brain (hypothalamus)*, it helps people *eat less without conscious effort*, leading to *significant and sustained weight loss*.
