Wegovy: What It Is, How It Works, and What You Need to Know

Wegovy, a once-weekly injectable medication approved for chronic weight management in adults. Also known as semaglutide, it’s part of a class of drugs called GLP-1 receptor agonists that mimic a natural hormone in your body to help control appetite and slow digestion. Unlike older weight loss pills that just suppress hunger, Wegovy works at the brain level to reduce cravings and make you feel full longer—without the jittery side effects of stimulants.

Wegovy isn’t a magic pill, but it’s one of the most effective tools doctors now have for treating obesity. Studies show people using Wegovy lost an average of 15% of their body weight over a year—some lost even more—when combined with diet and exercise. It’s not meant for quick fixes or cosmetic use. It’s designed for adults with a BMI of 30 or higher, or 27 with weight-related conditions like high blood pressure or type 2 diabetes. The FDA approved it based on real clinical trials, not marketing hype.

Wegovy is closely related to semaglutide, the same active ingredient in Ozempic, which is approved for type 2 diabetes. The difference? Wegovy is dosed higher specifically for weight loss. It’s also different from older weight loss drugs like phentermine or orlistat, which often cause harsh side effects like dry mouth, diarrhea, or increased heart rate. Wegovy’s main side effects are nausea, vomiting, or constipation—usually mild and temporary as your body adjusts.

People often ask if Wegovy is safe long-term. So far, data shows it’s well-tolerated when used as directed. But it’s not for everyone. If you have a personal or family history of medullary thyroid cancer or multiple endocrine neoplasia syndrome type 2, you should avoid it. It’s also not recommended during pregnancy or if you’re planning to become pregnant. Always talk to your doctor before starting—not just for safety, but to make sure it fits your health goals.

Wegovy doesn’t work alone. It’s most effective when paired with lifestyle changes: eating more protein and fiber, cutting back on ultra-processed foods, moving more, and getting enough sleep. Many users report that after a few weeks on Wegovy, they naturally start choosing healthier foods because they don’t crave sweets or snacks as much. That’s the hormone at work—not willpower.
