How much weight should you expect to lose on Wegovy?

The myth: Wegovy produces the same loss for everyone

The 15% figure from STEP 1 is real, but it is an average across roughly 1,300 adults taking the 2.4mg maintenance dose. In practice, the range is wide. Some participants lost closer to 5%; others exceeded 20%. A handful lost very little. Weight loss on semaglutide reflects how your body responds to GLP-1 receptor agonism, how consistently you manage your diet, how much activity you build in, and whether the dose is titrated to the level you can tolerate. Starting dose is 0.25mg, stepping up gradually over months under prescriber guidance until reaching 2.4mg, or the highest dose you can comfortably hold. The relationship between semaglutide dose and weight loss explains why the titration phase matters so much to your overall result.

The new 7.2mg dose, approved by the MHRA in January 2026 and now available as a dedicated single-dose pen, brought trial data of around 20.7% average loss over 72 weeks, narrowing the gap with tirzepatide. That is a higher ceiling, but it is still an average, not a floor. If you are wondering how much you can realistically expect to lose on Wegovy, the answer depends on your individual response, your dose, and how well you sustain the lifestyle changes alongside it. Our guide on how much weight you should be losing on Wegovy is a useful reference point, because weekly progress patterns look different from month-average data too, which catches many people off guard early on. Understanding how much weight you should lose per week on Wegovy adds further detail on what typical weekly progress looks like in practice.

What headline Wegovy prices often leave out

Private Wegovy costs in the UK vary between providers, and the figures quoted online are not always the full picture. A headline price may cover the pen itself but exclude the consultation, the prescription, delivery, and any follow-up clinical support when you move to a higher dose. Those costs exist; they are just presented separately or quietly absorbed into a subscription you may not have noticed. If you cancel before a review cycle, you may find you have paid for clinical time you never used, or lose access to aftercare mid-titration.

It is worth checking what the quoted price actually includes before comparing numbers. For context: Eli Lilly's September 2025 list-price rise pushed tirzepatide pens to around £149–£375 per month by dose; Wegovy sits within a comparable private market range, varying by dose and provider. Those figures are reported market context only, and your own cost will depend on the dose you reach. Timing matters practically too, if your next pen is due just after a bank holiday weekend, or you order on a Monday after payday, knowing whether your provider dispatches the same day makes a difference to how smoothly treatment runs.

The Wegovy cost guide sets out what UK private pricing typically looks like dose by dose, and how those prices compare across the market. What the numbers rarely reflect is the clinical workload behind a legitimate prescription (identity verification, weight confirmation, prescriber review, GP notification) all of which protect you.

What num's transparent price actually covers

nume is not the cheapest option. That is deliberate. One price covers the free consultation, the prescription (if clinically approved), the treatment itself, and free next-working-day delivery tracked by DPD. Aftercare is included, seven days a week. There is no subscription, no auto-renewal, and every repeat order is reviewed by a prescriber before dispatch. A real clinician reads your consultation answers the same day, not software, not a queue.

The Wegovy treatment page shows current pricing transparently. If you want to understand how much Wegovy slows down digestion and how that affects your appetite and eating habits throughout treatment, or how to eat alongside Wegovy, those are questions our prescribers handle as part of ongoing aftercare, not extras you pay for separately. See our clinical team for more on who is reviewing your care.

Why the cheapest Wegovy listing answers the wrong question

For most purchases, lowest price is a reasonable guide. A prescription medicine is different. Wegovy requires a valid prescription from a qualified prescriber who has assessed your health, your other medicines and your suitability for treatment. The NHS semaglutide guidance and NICE's appraisal TA875 both make clear that this is a treatment to be used within a clinical framework, not purchased like a supplement. The MHRA has warned repeatedly about counterfeit weight-loss pens sold online without a clinical assessment; some have contained incorrect substances. A small saving is not the measure that keeps you safe.

If you have found a source advertising Wegovy at a price that seems far below market, that is a red flag, not a bargain. Verify any online pharmacy on the GPhC register before purchasing, it takes about thirty seconds and tells you whether the pharmacy is legitimate. Report anything suspicious at yellowcard.mhra.gov.uk. The right question when choosing a Wegovy provider is not who is cheapest, but who has the clinical infrastructure to get your treatment right and keep you safe throughout. Start with your free consultation to see whether Wegovy is clinically suitable for you.
