How Much Weight on Average People Lose on Wegovy

The myth that everyone loses the same amount on Wegovy

The 15% average from the STEP 1 trial is widely quoted, and it is a genuine, peer-reviewed figure published in the New England Journal of Medicine. But an average conceals a wide spread. In STEP 1, some participants lost considerably more than 15%; others lost less. A number of factors shaped those differences: baseline weight, how consistently participants made the lifestyle changes the trial required, individual metabolic response, and how long they stayed on treatment.

The idea that Wegovy produces the same result in every person who takes it is the misconception worth setting aside gently here, because it shapes how people think about both the medicine and its cost. If the outcome varies, then the question "is Wegovy worth it?" cannot be answered with a single number. It needs an honest conversation with a clinician about your own situation.

Results at the newer 7.2 mg dose are closer to those seen with tirzepatide, a useful comparison if you want to weigh the two licensed options; our page on how much weight can be lost on Wegovy covers the dose-by-dose evidence in more detail. Both medicines are prescription-only and both require clinical assessment before anything is prescribed.

What UK private Wegovy pricing actually covers, and what it often does not

Private Wegovy pricing in the UK varies by provider and by dose. As a general guide, reported private market prices have ranged from roughly £150 to over £300 per month depending on the strength, and that range has shifted since Eli Lilly's list price increases in 2025 affected the broader GLP-1 market; if you want to understand what sits behind those figures, our guide to the average cost of Wegovy sets out how the numbers are built up and what can push them higher or lower. These figures are reported; actual prices differ between pharmacies and you should always confirm directly with the provider.

What matters more than the headline number is what that number includes. A low advertised price frequently covers the medicine alone. It may not include the consultation, the prescription fee, delivery, or any clinical support if you have a question mid-treatment. Those costs stack up. A more detailed breakdown of what drives the monthly figure (and how to read it accurately) is on our average monthly cost of Wegovy page.

At nume, one price covers the consultation, the prescription, the treatment itself, free next-working-day tracked delivery and 7-day aftercare. There are no repeat subscription charges and no hidden fees. We are not the cheapest option available, that is a deliberate choice, because a service built around clinical safety has costs that a bare-medicine listing does not. You can see what is included on our Wegovy price page.

Why "cheapest" is not the right test for a prescription medicine

Wegovy is a prescription-only medicine regulated by the MHRA. The only legal route to it in the UK is through a prescriber who has assessed your health, your history and whether treatment is appropriate. That assessment is not a formality, it is the part of the process that keeps you safe. NHS England's guidance on weight-management injections is clear that these medicines are used alongside diet and activity support, with clinical monitoring throughout.

Sellers offering these medicines at prices far below market rate, without any visible clinical process, are a genuine concern. The MHRA has warned publicly about counterfeit weight-loss pens sold online, some of which have contained insulin rather than semaglutide. Checking that any pharmacy you use is listed on the GPhC register takes about thirty seconds. It is worth doing. Suspect sellers can be reported through the Yellow Card scheme at yellowcard.mhra.gov.uk.

A small saving on the headline price is not the measure that keeps you safe on a medicine like this. What matters is that the supply chain is legitimate, the prescriber is qualified and the support is there if you need it. Understanding how results build over time is part of that picture, and our page on average Wegovy weight loss per month explains how losses typically progress as the dose increases, while our page on average monthly weight loss on Wegovy looks at how those figures compare across different patient groups. Our Wegovy cost-effectiveness page looks at how to think about value across a full course of treatment, rather than per pen. If you are ready to find out whether Wegovy is right for you, start your free consultation and a GPhC-registered prescriber will review your details the same day.
