What is Wegovy?

Wegovy is the brand name for semaglutide, a medication originally developed for type 2 diabetes management. The U.S. Food and Drug Administration approved Wegovy specifically for chronic weight management in June 2021. Manufactured by Novo Nordisk, this medication belongs to a class of drugs called GLP-1 receptor agonists, which work by mimicking a naturally occurring hormone in the body that regulates appetite and food intake.

How Wegovy Works

The science behind Wegovy is rooted in its ability to activate GLP-1 receptors in the brain, particularly in areas that control appetite and food consumption. When administered, semaglutide slows gastric emptying, meaning food stays in the stomach longer, creating a prolonged feeling of fullness. Additionally, it helps regulate blood sugar levels and reduces cravings, making it easier for patients to adhere to reduced-calorie diets.

Wegovy is administered through a once-weekly subcutaneous injection, which patients can self-administer using a pre-filled pen. The treatment begins with a lower dose that gradually increases over several months, allowing the body to adjust and minimizing potential side effects.

Clinical Effectiveness

Clinical trials have demonstrated impressive results for Wegovy users. In the landmark STEP trials, participants taking Wegovy lost an average of 15% of their body weight over 68 weeks when combined with lifestyle modifications. This represents a substantial improvement over traditional weight loss methods and earlier pharmaceutical options. Some participants experienced even greater weight loss, with approximately one-third losing 20% or more of their body weight.

Related Medications and Brands

Wegovy exists within a growing family of GLP-1 medications. Ozempic, also containing semaglutide, is approved for type 2 diabetes but has been used off-label for weight loss. Saxenda, containing liraglutide, was an earlier GLP-1 medication approved for weight management. More recently, Zepbound (tirzepatide) has entered the market, offering a dual-action approach by targeting both GLP-1 and GIP receptors.

Each brand has unique characteristics, dosing schedules, and approval indications, but they share the common mechanism of appetite suppression and metabolic regulation.

Considerations and Side Effects

While Wegovy offers significant benefits, it’s not without considerations. Common side effects include nausea, diarrhea, vomiting, constipation, and abdominal pain. These effects are typically most pronounced when starting the medication or increasing doses. Wegovy is intended for adults with a body mass index of 30 or higher, or 27 or higher with at least one weight-related condition such as high blood pressure or type 2 diabetes.

The medication requires a long-term commitment, as discontinuing Wegovy often results in weight regain. It’s also important to note that Wegovy works best when combined with a reduced-calorie diet and increased physical activity.

Wegovy represents a powerful tool in the fight against obesity, offering clinically proven weight loss results that surpass many previous pharmaceutical interventions. As part of a comprehensive weight management strategy that includes dietary changes and exercise, Wegovy provides new possibilities for individuals struggling with excess weight and related health conditions.
