Semaglutide for Weight Loss: What It Is, Who It Works For, and What You Need to Know

When you hear semaglutide, a prescription medication originally developed for type 2 diabetes that also triggers significant weight loss by reducing appetite and slowing digestion. Also known as Wegovy when used for weight loss, it’s one of the most talked-about drugs in modern medicine. It’s not a magic pill, but for many people struggling with obesity, it’s the first tool that actually works without extreme dieting or surgery.

It’s part of a class of drugs called GLP-1 agonists, hormone-like compounds that mimic the body’s natural appetite-control signals. Also known as incretin mimetics, they help your brain feel full faster and keep food moving slower through your stomach. That’s why people on semaglutide often eat less without feeling hungry. The same drug, sold as Ozempic, the brand name for semaglutide when prescribed for diabetes. Also known as diabetes medication, it’s the same molecule—but higher doses are approved specifically for weight loss under the name Wegovy. Many people wonder if they can use Ozempic for weight loss off-label. The answer? It’s possible, but insurance rarely covers it unless you have diabetes.

Not everyone is a candidate. If you have a personal or family history of thyroid cancer, especially medullary thyroid carcinoma, or multiple endocrine neoplasia syndrome type 2, semaglutide is off-limits. People with a history of pancreatitis or severe gastrointestinal issues may also face risks. And while it helps with fat loss, it doesn’t fix poor sleep, stress, or inactivity. You still need to move, eat well, and manage your habits—semaglutide just makes it easier.

Insurance coverage is a big hurdle. If you’re trying to get Wegovy, the FDA-approved weight loss version of semaglutide. Also known as semaglutide for weight loss, it’s often denied unless you meet strict BMI and medical criteria, you’ll likely need prior authorization. Companies like Express Scripts may require proof of failed diet attempts, lab results, or even a referral from a weight loss clinic. If your claim gets denied, appeals are possible—but they take time and documentation.
