What is Ozempic and How Does It Work?
Ozempic (semaglutide) is a once-weekly injectable medication originally developed for type 2 diabetes but increasingly prescribed off-label for weight loss. As a GLP-1 receptor agonist, it mimics the hormone GLP-1, which regulates blood sugar and slows gastric emptying, leading to reduced appetite and significant weight loss.
