wegovy

Introduction

 

Wegovy (semaglutide 2.4 mg) is one of the most effective FDA-approved medications for weight loss on the market today. It’s helped thousands of people lose significant weight without surgery and has become a go-to prescription for healthcare providers treating obesity.

 

In this guide, you’ll learn exactly how Wegovy works, what kind of results to expect, how the dosing schedule works, and what to know about side effects and safety.

 

What Is Wegovy?

 

Wegovy is a GLP-1 receptor agonist, which means it mimics a natural hormone called glucagon-like peptide-1. This hormone affects parts of your brain that control appetite and digestion.

 

Wegovy helps you lose weight by:

  • Reducing appetite and cravings
  • Slowing how quickly food leaves your stomach (so you feel fuller longer)
  • Helping regulate blood sugar and insulin levels

Who Is Wegovy For?

 

Wegovy is FDA-approved for:

  • Adults with a BMI ≥30 (obese), or
  • Adults with a BMI ≥27 who also have a weight-related condition (such as high blood pressure, diabetes, or sleep apnea)

💡 It is not approved for cosmetic weight loss or short-term use.
