Getting Off Wegovy: What Happens When You Stop Taking It

What clinical trials found when participants stopped semaglutide

The STEP 1 trial (which ran for 68 weeks with semaglutide 2.4mg) produced an average body-weight reduction of around 15% compared with placebo, as published in the New England Journal of Medicine. What happened next is less often quoted but just as important. In the one-year withdrawal extension, participants who stopped semaglutide regained, on average, about two-thirds of the weight they had lost. Cardiometabolic improvements (blood pressure, cholesterol, blood sugar) also partially reversed.

This reflects the underlying biology rather than any failure on the individual's part. Semaglutide works by activating GLP-1 receptors that regulate appetite, slow gastric emptying and reduce food-seeking behaviour. When the drug is no longer present, those signals revert to baseline. The body's set-point doesn't change simply because the medicine was taken for a period; weight management as a condition tends to be long-term.

A question our prescribers hear most weeks is whether stopping Wegovy means all the progress is undone. Clinically, it's more nuanced than that: the weight trajectory after stopping depends on what lifestyle changes have been embedded during treatment, the dose at which someone stops, and whether any underlying health conditions have improved enough to change the picture independently.

Why people stop, and what it means for how you do it

Reasons for stopping Wegovy vary considerably. Some people reach a weight they are happy maintaining and want to see whether they can sustain it without the medicine. Others stop because of side effects, cost, planned pregnancy, or an upcoming surgical procedure. The reason shapes the approach.

If you are stopping because of side effects, your prescriber may suggest stepping back to a lower dose before discontinuing rather than stopping at your current level, not because semaglutide is pharmacologically dependent in the way some medicines are, but because a lower dose may resolve the side effect while preserving some benefit. If you are stopping ahead of surgery, NHS England's guidance on weight management injections advises telling your anaesthetist about GLP-1 treatment, and many surgeons now ask patients to pause before a procedure because of aspiration risk under anaesthesia. Your surgical team will tell you how far in advance to stop.

If you are stopping because of a planned pregnancy, the advice from the MHRA is clear: semaglutide is not recommended in pregnancy, breastfeeding, or for those actively trying to conceive. A wash-out period applies before trying to conceive, the exact duration is confirmed by your prescriber, not a fixed public figure. If oral contraceptives are part of your routine, note that starting Wegovy carries specific guidance on contraception too; stopping it generally does not carry the same instruction, but any hormonal changes are worth discussing.

How to approach the conversation with your prescriber

There is no single licensed tapering protocol for stopping Wegovy in the UK. The NHS guidance on semaglutide advises patients not to stop taking it without talking to their doctor or pharmacist first, a principle that applies whether you've been on it for three months or three years. The absence of a formal taper doesn't mean stopping is without planning; it means the plan is individual.

Things worth discussing with your prescriber: whether your reason for stopping is permanent or temporary, what dose you're currently on, whether there are alternatives worth considering (including whether a lower maintenance dose might achieve acceptable results at lower cost, for context on how Wegovy pricing works, this page covers the cost landscape), and what monitoring would be helpful in the weeks after you stop.

If you took Wegovy through an online service and your prescriber is remote, the same principle applies. At nume, every repeat order involves a fresh clinical review, which means if a patient's circumstances have changed, including a desire to stop, that conversation can happen at the repeat stage. You don't need a separate appointment to raise it. The dedicated guidance on how to get off Wegovy covers the process in more detail if you want a step-by-step framework.

Looking after yourself after stopping

The return of appetite after stopping semaglutide is real and, for many people, rapid. Within a few weeks of the last dose, hunger levels typically return to where they were before treatment, sometimes more acutely because the contrast is noticeable. Planning for this in advance (rather than being caught off guard) makes a practical difference.

NHS guidance on healthy weight maintenance consistently highlights protein adequacy, regular physical activity (particularly resistance exercise to preserve lean mass), and routines around mealtimes as the practical tools available once medicine is stopped. These are more effective if they've been practised during treatment rather than started from scratch afterwards.

If weight begins to return at a rate that concerns you, or if a health condition that improved during treatment begins to worsen, that is clinical information worth acting on. Going back onto semaglutide, or exploring the broader semaglutide options that exist, is a legitimate medical decision, not an admission of defeat. Obesity is a condition with a biological basis, and treatment timelines are set by health, not by an arbitrary endpoint.
