Can you stop Wegovy after 6 months — and what happens when you do?

What actually happens to your weight when you stop Wegovy at six months?

This is the question most people are really asking, and the honest answer is: the weight tends to come back. The STEP 1 trial (published in the New England Journal of Medicine) followed participants after they stopped semaglutide 2.4mg and found that within a year of stopping, much of the weight lost had returned. That is not a flaw in the medicine; it reflects the biology of appetite regulation. Semaglutide suppresses hunger signals that are physiological, not behavioural. Remove the medicine and those signals reassert themselves.

Six months is also a fairly early point in a full treatment course. Many people are still working through the dose titration at that stage, moving from the starter dose up through 0.5mg, 1.0mg, 1.7mg, towards the 2.4mg maintenance level, each step roughly four weeks apart. If you are on the 1.7mg stage at six months, you may not yet have reached the dose where results are most pronounced. Stopping at that point means stopping before the treatment has had the best opportunity to work.

None of this means stopping is wrong. It means it is worth understanding before you do it. The NHS medicines information on semaglutide notes clearly that stopping treatment is likely to result in weight regain, and that this should be discussed with a prescriber.

What does the NICE guidance say about the six-month mark?

NICE's recommendation for semaglutide (Wegovy) includes a specific six-month review criterion. If a patient has not lost at least 5% of their starting body weight after six months on the maintenance dose, continuing treatment should be reconsidered. That is a clinical trigger for a conversation, not an automatic stop, and not a reason to panic if you are making progress more slowly than you hoped.

The inverse also matters: if you have lost more than 5% at six months, that is exactly the situation the guidance envisions as supporting continuation. NICE's recommendation also specifies that Wegovy should be used for a maximum of two years within appropriate clinical oversight, so six months is not the end of the road for most people who are responding well.

If you are weighing up what treatment costs look like across a longer course, our Wegovy price comparison page gives an honest breakdown of what to factor in. Cost is a real consideration, but it is a separate one from the clinical question of whether to stop.

It is worth knowing that if you stopped earlier (say at three months) the picture looks similar but with less weight lost to begin with. Our page on stopping Wegovy after three months covers that scenario directly.

Are there situations where stopping Wegovy at six months is the right clinical call?

Yes. There are several circumstances where stopping at or around six months is appropriate, sometimes even necessary. Pregnancy is the clearest example: Wegovy is not recommended during pregnancy, while breastfeeding, or for anyone trying to conceive, so if your situation changes in any of these ways, stopping promptly is the right course. Surgery is another: NHS England advises patients to tell their healthcare team, including the anaesthetist, that they are taking a GLP-1 medicine before any procedure, and some surgical teams request a pause in advance.

Persistent, intolerable side effects are also a legitimate reason. Most GI side effects settle after the first weeks of a new dose, but in a minority of people they do not. If nausea, vomiting or other symptoms remain significant and are affecting quality of life despite clinical support, stopping is a reasonable outcome, not a failure. If you have found the injection format difficult, it is worth knowing that the oral semaglutide option exists; the semaglutide overview covers both formats.

If your reasons for stopping are practical rather than medical (cost, logistics, the injection routine) those are worth raising with a prescriber too, because there may be options you have not considered. Our team at nume reviews every repeat order clinically, and those consultations are the right place to have an honest conversation about whether continuing makes sense for you specifically.

If I stop, is there a right way to do it?

Wegovy does not typically require a medical taper the way some other medicines do (you can stop without a formal dose-reduction schedule) but abrupt stopping can still catch people off-guard. Appetite often increases noticeably within days to weeks. Some people find the rebound hunger harder to manage than the original weight gain was. Planning for that (with support around diet and activity) makes a real difference to outcomes after stopping.

If you are thinking about stopping because you feel you have reached a plateau at six months, it may be worth looking at what Wegovy progress at six months typically looks like before making that decision. A plateau is not always a signal that treatment has stopped working; sometimes it reflects the body adjusting ahead of the next phase. Equally, if you are earlier in your journey and wondering whether you are on track, our pages on progress at two months and three months give context for those earlier stages.

If you are ready to discuss your options properly, speak to our prescribers, every consultation at nume is reviewed the same day by a real clinician, not automated software, and there is no charge for the consultation itself.
