GLP-1 Agents: What They Are, How They Work, and What You Need to Know
When you hear GLP-1 agents, a class of injectable medications that mimic a natural hormone in your gut to control blood sugar and reduce appetite. Also known as GLP-1 receptor agonists, they’re not just for diabetes—they’ve become one of the most talked-about tools for weight management in recent years. These drugs work by slowing digestion, telling your brain you’re full faster, and helping your pancreas release insulin only when needed. Unlike older diabetes meds that force your body to produce more insulin all the time, GLP-1 agents respond to your actual blood sugar levels, which means fewer crashes and less risk of low blood sugar.
Two of the most common names you’ll hear are semaglutide, a once-weekly injection linked to significant weight loss in clinical trials. Also known as Wegovy and Ozempic, it’s used for both diabetes and obesity, and liraglutide, a daily injection originally approved for diabetes and later for weight loss under the brand name Saxenda. Also known as Saxenda and Victoza, it’s been used for over a decade. These aren’t magic pills—they work best when paired with diet and movement. But for many people who’ve struggled with weight loss or blood sugar control, they’ve been a game-changer. What’s more, research shows they can reduce the risk of heart attacks and strokes in people with type 2 diabetes, which is why doctors are now prescribing them for more than just glucose control.
