How Much Weight Do You Lose Weekly on Wegovy?

The question behind the question: are you deciding whether Wegovy is worth it?

If you are searching for a weekly weight-loss figure, you are probably weighing a real decision: is this treatment likely to work for me, and does the cost make sense given what I might achieve? That is the right frame. Wegovy is not a quick intervention. The dose starts low, at 0.25mg, and is increased gradually by your prescriber over roughly five months before reaching the 2.4mg maintenance level. During that ramp-up, weekly losses tend to be modest — often 0.3–0.7kg. Once established at maintenance, some weeks will show more, some less, because weight does not leave the body in a straight line.

The week-by-week pattern in trials reflects this: heavier losses tend to cluster in the middle phase of treatment, slowing as you approach a new set point. Expecting a fixed number every single week sets most people up for unnecessary disappointment. The more useful question is what the trajectory looks like over months, and the trial evidence on that is genuinely encouraging, provided treatment is clinically appropriate for you.

The NICE appraisal of semaglutide for weight management, TA875, notes that treatment should continue only if at least 5% of body weight has been lost after six months at the maintenance dose. That threshold gives you a practical benchmark: if the medicine is working for your biology, meaningful progress should be visible well within half a year.

What the first week and the first month actually look like

The first week of Wegovy often produces a noticeable drop, partly fat, partly fluid, partly the effect of eating less because nausea is common early on. That initial figure can flatter the long-term average, so it is worth keeping in perspective. By the end of the first month, losses are typically in the 1–3kg range for most people, though some see more and others less.

Looking at monthly rather than weekly progress tends to give a cleaner picture. The body responds to semaglutide by reducing appetite signals and slowing gastric emptying, and those changes compound over time. Weeks where the scales barely move often precede weeks of clearer progress. A prescriber can help you interpret whether your pattern is within the expected range or whether a clinical conversation about your dose is needed.

One thing our prescribers hear regularly: people who track weight daily find the variation stressful in a way that weekly or fortnightly check-ins simply do not. That is a small practical point worth knowing before you start.

How private Wegovy pricing actually works in the UK, and what matters more than the headline figure

Private treatment prices for Wegovy in the UK vary by dose and provider. Any legitimate price for a prescription medicine should include a clinical consultation and the prescriber's assessment, a headline pen price that excludes those things tells you less than it appears to. Eli Lilly's September 2025 list-price increase for Mounjaro was widely reported as a marker of how quickly manufacturer pricing can shift; Novo Nordisk's pricing for Wegovy follows its own trajectory, and what you pay privately will depend on the dose you reach and how the service structures its fees.

Delivery charges, aftercare access, and the cost of clinical re-reviews before each repeat are all things worth checking before committing. You can find a clear breakdown of how Wegovy is priced and what is typically included on our dedicated cost page, and a fuller look at the overall cost of a Wegovy treatment course covers what the investment looks like over several months.

At nume, one price covers everything: the consultation, the prescription, the treatment, and free next-working-day delivery by DPD in plain packaging. We are not the cheapest option available, and we are not trying to be. What that price buys is a named prescriber reviewing your case the same day, clinical oversight before every repeat, and a service built around the GPhC-registered pharmacy you can verify yourself. Details of current treatment pricing are on the treatment page.

Why 'cheapest Wegovy' is the wrong question for a prescription medicine

Wegovy is a Prescription-Only Medicine. The clinical assessment is not a formality sitting alongside the product, it is the part that keeps you safe. A seller offering semaglutide without a proper clinical consultation, or at prices that seem implausibly low, is a genuine concern. The MHRA has warned publicly about counterfeit and illegally traded weight-loss pens, and reports of suspect sellers can be made via the Yellow Card scheme. Fake pens have been found to contain the wrong substance entirely.

The measure that matters is not cost per pen, it is whether you are receiving a genuine medicine, assessed and dispensed by a regulated professional, with clinical support if anything changes. That is what a clinician-led service is built to provide.

If you are ready to find out whether Wegovy is clinically suitable for you, the weight-loss treatment overview covers the options, and our clinical team (you can read about our approach on the clinical team page) is available seven days a week once you are a patient. Start with a free consultation; there is no obligation until a prescriber has reviewed your answers and confirmed suitability.
