Four key factors can greatly impact how much weight people lose while taking GLP-1 drugs like Ozempic, Wegovy, Victoza, and Saxenda. Here's what to know.

Many people are doing an end-run around their doctor's office, reaching out to potentially unreliable sources that promise to set them up with Wegovy, Zepbound and other weight-loss drugs.

Half a century of advancements in biomedical science paved the way for today's powerful weight-loss drugs like Ozempic -- so what was that journey like for the scientists involved?

Research has shown there are plenty of perks of using a medication like Ozempic for weight loss. But, given that this is a drug, there are some potential downsides to consider, too. New research published in JAMA Network Open links GLP-1 receptor agonists—a class of medications that includes semaglutide medications like Ozempic and Wegovy—to a loss of bone density.
