Introduction
Wegovy has changed the game for weight loss. This FDA-approved shot helps many people who struggle with obesity. Since its 2021 approval, Wegovy has shown amazing results in clinical tests. Let’s explore what Wegovy is, how it works, and if it might be right for you.
What is Wegovy?
Wegovy is a prescription shot that contains semaglutide 2.4mg. Novo Nordisk made it just for weight management. It’s like Ozempic (also semaglutide) but stronger and made for weight loss, not diabetes.
How It Works
Wegovy works in several ways to help you lose weight:
- It acts like a hormone called GLP-1 that controls hunger
- It tells your brain you’re not hungry
- It keeps food in your stomach longer so you feel full
- It helps control blood sugar
- It might make high-calorie foods less tempting
“Wegovy works on the brain’s hunger control centers,” says Dr. Robert Kushner from Northwestern University. “This tackles a main cause of weight gain.”
Does It Really Work?
The STEP trials tested Wegovy before FDA approval. The results were impressive.
What the Studies Show
- People lost about 15% of their weight over 68 weeks (versus 2.4% with fake pills)
- People with type 2 diabetes lost about 10% of their weight
- When paired with lifestyle coaching, weight loss reached nearly 17%
- Stopping treatment led to weight gain, showing ongoing use matters
Dr. Jamy Ard from Wake Forest notes: “The weight loss with Wegovy beats other weight loss drugs. It comes close to what some get from surgery.”
More Than Just Weight Loss
Wegovy also helps with:
- Heart health
- Blood sugar control
- Lower blood pressure
- Less body inflammation
- Better mobility
- Improved quality of life
- Less severe sleep apnea
A major study in 2023 found it cut heart risks by 20% in overweight people with heart disease.
Who Should Try Wegovy?
Wegovy is approved for:
- Adults with a BMI of 30 or higher (obesity)
- Adults with a BMI of 27 or higher (overweight) who also have health issues like high blood pressure or diabetes
Think About This First
Wegovy isn’t for everyone:
- It’s not for people who just want to lose a few pounds
- You need to use it long-term for lasting results
- It works best with diet and exercise changes
- You need regular doctor checkups
- It can be costly if insurance won’t cover it
What to Expect on Wegovy
How to Take It
You take Wegovy as a weekly shot under your skin. The dose starts small and increases over time:
- Week 1-4: 0.25 mg weekly
- Week 5-8: 0.5 mg weekly
- Week 9-12: 1.0 mg weekly
- Week 13-16: 1.7 mg weekly
- Week 17+: 2.4 mg weekly
How to Use It
The medicine comes in pens with hidden needles. You inject it into your belly, thigh, or upper arm. Change the spot each week.
When You’ll See Results
Most people start to lose weight within 4-8 weeks. The biggest changes happen around 6-12 months:
- First month: You might lose 1-3% of your weight
- Three months: About 5-7% weight loss
- Six months: Steady weight loss continues
- One year+: Best results with ongoing use
Side Effects to Know About

- Nausea (44% of users)
- Diarrhea (30%)
- Vomiting (24%)
- Constipation (24%)

These issues often get better as your body adjusts.

Important Warning
In 2023, the FDA added a warning about thyroid tumor risks. You shouldn’t take Wegovy if you or your family have had certain thyroid cancers.
Dr. Katherine Saunders from Weill Cornell explains: “Most patients handle the side effects well with good medical care. For those who qualify, the benefits usually outweigh the risks.”

Common Questions
How much weight will I lose?
Most people lose 15-17% of their starting weight after 68 weeks. Your results may vary based on your genes, starting weight, lifestyle, and other health issues.
Is Wegovy the same as Ozempic?
Both contain semaglutide, but Wegovy uses a higher dose (2.4mg) and is approved for weight loss. Ozempic (up to 2mg) is for diabetes. They also have different devices and insurance coverage.
Will my insurance cover it?
It varies widely. Most plans require:
- Proof of obesity or overweight with health problems
- Failed weight loss attempts
- Participation in a weight program
- Prior authorization
What happens if I stop taking it?
Most people regain weight. In one study, people who stopped Wegovy regained about two-thirds of their lost weight within a year. Many need to stay on it long-term.
Can I use it during pregnancy?
No. Wegovy might harm a developing baby. Women should use birth control while taking it and stop at least two months before trying to get pregnant.
How is it different from older weight loss drugs?
Wegovy works better than older drugs. Previous medications typically led to 5-10% weight loss and often had heart or mood side effects. Wegovy offers 15-17% weight loss with mainly digestive side effects.
Conclusion
Wegovy marks a big step forward in medical weight loss. It offers real help for people struggling with obesity despite trying lifestyle changes.
But it’s not a miracle cure. It has side effects, costs, and requires ongoing treatment. Talk with your doctor about whether Wegovy makes sense for you. Set realistic goals and commit to healthy lifestyle changes too.
Research continues to grow, and we’ll learn more about how best to use Wegovy. For now, it stands as a valuable option for tackling obesity—a tool that, when used right, can truly change lives.
