Question 1

How does Wegovy work?

Accepted Answer

Wegovy (semaglutide) is a GLP-1 receptor agonist that mimics a natural gut hormone to regulate your blood sugar levels and suppress your appetite.

It works by:

Reducing appetite, making you feel less hungry.
Reducing cravings, helping you make healthier choices.
Lowering your ‘set point’, allowing for more weight loss before you reach a plateau.

Wegovy is most effective when combined with healthy lifestyle changes, including a balanced diet and regular exercise.

Question 2

How effective is Wegovy?

Accepted Answer

At the current maximum dose of 2.4 mg, Wegovy has been shown to support an average weight loss of 17.5%.

In more recent studies, the upcoming 7.2 mg dose, expected to launch later this year, demonstrated even greater results with an average weight loss of 20.7%.

Individual results may vary depending on how your body responds to treatment, along with factors like diet, activity levels, and consistency.

Question 7

Wegovy dosage

Accepted Answer

Your journey with Wegovy typically follows a gradual dose increase to help your body adjust and minimise side effects:

Month 1: Start with 0.25mg per week
Month 2: Increase to 0.5mg
Month 3: Dose increases to 1mg
Month 4: If tolerated, increase to 1.7mg
Month 5: Final increase to 2.4mg

That said, you’re always in control. If a lower dose effectively manages your appetite and helps you progress, there’s no pressure to increase. In the Voy app, you can choose to stay on the dose that feels right for you—whether it’s the one your body tolerates best or the one that gives you the results you’re looking for.

A new 7.2mg dose of Wegovy is also expected to launch later this year. In recent studies, it has shown even greater weight loss potential for those who need or can tolerate a higher dose. More details will be available once it becomes accessible in the UK.

Question 8

Maintenance dose

Accepted Answer

Your maintenance dose is the level you’ll transition to once you’ve reached your weight loss goal. This phase is all about maintaining your results, preventing further weight loss, and reducing the risk of regaining weight. It’s a crucial part of protecting the progress you’ve made and supporting a long-term, sustainable future.

For some people, maintenance may involve staying on a lower dose long term to help maintain their results. For others, it might mean coming off treatment entirely. Either way, it’s all about finding what works best for you.
