Wegovy (semaglutide) is a newly approved medication by the FDA that has gained attention for its role in weight management, particularly for adults struggling with obesity or overweight. As a family medicine and obesity medicine physician, this is a medication that I have experience in utilizing to help improve my patients' health and wellbeing.
FDA Indications for Use
Wegovy is approved by the FDA for chronic weight management in adults with:
- A body mass index (BMI) of 30 or greater (obesity)
- A BMI of 27 or greater (overweight) with at least one weight-related condition such as hypertension, type 2 diabetes, or dyslipidemia.
Wegovy is intended to be used alongside a healthy diet and regular physical activity.
How Does Wegovy Help with Weight Management?
Wegovy mimics the action of GLP-1 (glucagon-like peptide-1), a hormone that regulates appetite and food intake. By activating GLP-1 receptors, Wegovy:
- Reduces Appetite: It helps you feel fuller sooner and decreases cravings, making it easier to adhere to a calorie-restricted diet.
- Delays Gastric Emptying: This leads to prolonged satiety after meals.
- Enhances Insulin Sensitivity: It may help improve blood sugar levels, making it beneficial for patients with insulin resistance.
Expected Weight Loss
Clinical trials have shown that patients taking Wegovy can expect to lose an average of 15-20% of their body weight over 68 weeks when combined with lifestyle changes. Individual results may vary based on many factors including adherence to dietary and exercise recommendations.
Common and Uncommon Side Effects
Like any medication, Wegovy has potential side effects. Common side effects may include:
- Nausea
- Diarrhea
- Vomiting
- Constipation
- Abdominal pain
Uncommon but more serious side effects can include:
- Pancreatitis
- Gallbladder disease (seen with any rapid weight loss)
- Kidney injury (often due to dehydration)
- Risk of medullary thyroid tumors (based on animal studies)

Duration of Treatment
The duration of treatment with Wegovy can vary. It is generally recommended for long-term use, as weight management is a chronic condition. Patients should be re-evaluated periodically to assess the ongoing need for medication and effectiveness.
Insurance Coverage and Cost Without Insurance
Insurance coverage for Wegovy varies by plan. Many insurance companies may cover it for patients meeting specific criteria related to obesity or weight-related conditions. Without insurance, the cost of Wegovy can be significant, typically ranging from $1,200 to $1,500 per month. Programs for patient assistance may be available, and it’s advisable for patients to consult their pharmacy or insurance provider for specific coverage details.
Other Medication Options for Weight Management
In addition to Wegovy, there are other medications approved for weight management, including:
- Saxenda (liraglutide): Another GLP-1 receptor agonist. However Saxenda is a daily injection compared to Wegovy which is a weekly injection.
- Zepbound (tirzepatide): A combination GLP-1 and GIP receptor agonist.
- Phentermine-topiramate (Qsymia): A combination that suppresses appetite.
- Bupropion-naltrexone (Contrave): Targets the brain's appetite control center.
- Orlistat (Alli, Xenical): A lipase inhibitor that reduces fat absorption.
Each of these medications has its own mechanisms of action, benefits, and side effects. I go into more detail in this video.
Conclusion
Wegovy represents a significant advancement in the pharmacological management of obesity and overweight. Understanding its role in weight management, potential side effects, and insurance considerations can help healthcare providers better support their patients in achieving sustainable weight loss and improving metabolic health.
Many patients at Missouri Metabolic Health are prescribed Wegovy along with a comprehensive treatment plan that includes lifestyle changes, regular follow-up, and supportive care.
