Semaglutide: What It Is, How It Works, and What Alternatives Exist
When you hear semaglutide, a GLP-1 receptor agonist used to treat type 2 diabetes and promote weight loss. Also known as Ozempic or Wegovy, it works by mimicking a hormone your body naturally makes to control blood sugar and appetite. Unlike older diabetes drugs that force your pancreas to pump out more insulin, semaglutide tells your brain you’re full and slows digestion—so you eat less and your blood sugar stays steadier.
This isn’t just another pill. It’s part of a new wave of medications that treat both diabetes and obesity by targeting the same biological pathway. That’s why you’ll see it listed alongside drugs like liraglutide, another GLP-1 agonist sold as Victoza and Saxenda, and tirzepatide, a dual GIP and GLP-1 activator marketed as Mounjaro. These aren’t just different names—they work differently, have different side effects, and suit different needs. For example, semaglutide is injected once a week, while some older options need daily doses. And while Ozempic is approved for diabetes, Wegovy is the same drug but at a higher dose, approved specifically for weight loss.
People use semaglutide not just to lower A1C levels but to lose significant weight—often 15% or more of their body weight. That’s not magic. It’s biology. The drug reduces cravings, delays stomach emptying, and helps regulate hunger signals. But it’s not for everyone. Side effects like nausea, vomiting, or diarrhea are common at first. And if you have a history of thyroid cancer or pancreatitis, your doctor might avoid it. That’s why comparisons matter. You’ll find posts here that break down how semaglutide stacks up against metformin, GLP-1s like liraglutide, and even newer options like tirzepatide. You’ll also see how it fits into real-life routines—what to expect in the first weeks, how to manage side effects, and when to talk to your doctor about switching.
What you’ll find below isn’t just a list of articles. It’s a practical guide to understanding where semaglutide fits in the bigger picture of diabetes and weight management. You’ll see how it compares to other medications, what alternatives exist for people who can’t tolerate it, and how lifestyle changes can make it work better. No fluff. No marketing. Just clear, direct comparisons based on how real people use these drugs every day.
