If you’ve started Wegovy, or you’re thinking about it, you may be wondering when you’ll see a difference. It’s a question our pharmacists hear often, especially from people putting real effort into their weight loss. You might notice changes in your appetite within the first few weeks, with measurable weight loss developing over the following months. Changes in the mirror can take longer, so it is worth giving your body time to respond. Everyone’s experience is different, so try to give yourself time and notice the progress you’re making along the way.
How Do Wegovy Injections Work?
Wegovy injections contain semaglutide, a GLP-1 receptor agonist that mimics a natural hormone released after eating. According to the NHS, semaglutide supports weight loss by reducing your appetite and helping you feel fuller for longer, when combined with changes to diet and exercise.
Treatment starts at a low dose and increases gradually. This gives your body time to adjust and helps reduce side effects such as nausea, which is also why weight loss can build gradually rather than happen overnight.
What Does the Wegovy Weight Loss Timeline Look Like?
Weight loss with Wegovy is usually gradual, with the amount you lose varying as your dose increases. A rough timeline may look like this:
| Stage | Usual weekly dose | What you may notice |
| Weeks 1 to 4 | 0.25 mg | Smaller portions, fewer cravings |
| Weeks 5 to 8 | 0.5 mg | Early changes on the scales |
| Weeks 9 to 16 | 1 mg, then 1.7 mg | Steadier weight loss, clothes fitting differently |
| Week 17 onwards | 2.4 mg (maintenance) | More visible changes over the following months |
When Will Other People Notice?
There is no set point when other people will notice weight loss. You may feel a difference in how your clothes fit before changes are obvious in photos or to other people.
Why Your Wegovy Dosage Matters
Your Wegovy dosage can affect how your treatment progresses, because the early doses are designed for tolerance rather than maximum effect. Each step usually lasts four weeks, although your prescriber may keep you on a dose for longer if side effects are troublesome. You can learn more about how treatment is managed on our Wegovy injections page.
What Affects Your Wegovy Results?
Wegovy weight loss varies from person to person, and the medicine works best as part of a wider plan. In the main clinical trial, adults lost around 15% of their body weight on average over 68 weeks, alongside diet and activity support, but individual results differ.
Factors that can influence your progress include:
- Taking your injection on the same day each week
- A reduced calorie diet with enough protein
- Regular physical activity
- Sleep, stress and other health conditions

When Should You Speak to Your Prescriber?
Speak to your prescriber if you have seen little change after several months at your maintenance dose, or if side effects are affecting daily life. Seek urgent help for severe stomach pain that does not go away, as this can be a sign of a rare but serious side effect.

Frequently Asked Questions
Can you lose weight in the first month of Wegovy?
Some people do, although the starting dose is mainly there to help your body adjust. Early weight loss can be modest.
Why am I not losing weight on Wegovy yet?
You may still be on a lower dose. Results tend to become more noticeable once you reach your maintenance dose.
How long do people usually stay on Wegovy?
It depends on your goals and clinical needs. Your prescriber will review your progress regularly and advise on the right length of treatment.
Will I regain weight if I stop Wegovy?
Some people regain weight after stopping, particularly without lasting changes to diet and activity. Your prescriber can help you plan for this.
Is Wegovy suitable for everyone?
No. Wegovy is a prescription-only medicine, and a consultation is needed to check it is safe and appropriate for you.
