What Happens After 6 Months on Wegovy?

The biggest myth: that six months is when results plateau

Ask anyone searching "6 months Wegovy" what they expect and many will tell you they've heard the medicine stops working at this point, or that weight loss grinds to a halt. That's not what the evidence shows. The STEP 1 trial, published in the New England Journal of Medicine, ran for 68 weeks and found that weight continued to fall steadily throughout, the six-month mark fell well within the period of active, ongoing loss for most participants. A plateau in the rate of loss is normal and expected as the body adjusts, but that is different from results stopping altogether.

What six months often represents is a consolidation phase. By now, most people have worked through at least three or four dose increases. The nausea and digestive disruption that accompany each titration step have largely settled. Appetite suppression has become a familiar background state rather than something new and slightly disconcerting. That shift in experience can sometimes be mistaken for the medicine losing effect, when in reality it's working as intended, just more quietly.

If you feel you've stalled earlier than expected, it's worth reading about what the five-month mark looks like for context, because the arc of change across the middle months varies considerably from person to person.

Where most people actually are at the six-month point

Wegovy's licensed titration schedule moves in roughly four-week steps: 0.25mg, 0.5mg, 1.0mg, 1.7mg, and then 2.4mg as the standard maintenance dose. At a textbook pace that puts someone reaching 2.4mg around week 17, so by month six, many people have been on their maintenance dose for roughly three months. Others have needed longer at one or more steps because of tolerability, meaning they may still be at 1.7mg or even 1.0mg.

Neither scenario is a failure. The prescriber's job is to find the highest tolerated dose, not to hit a timetable. What matters clinically is captured in NICE's appraisal of semaglutide for weight management (TA875): if someone has lost less than 5% of their body weight after six months at their highest tolerated dose, the case for continuing should be reassessed. That threshold exists to protect patients, not to penalise slow starters, it's a review trigger, not an automatic stop.

For a sense of how this compares to the earlier months, the three-month mark and four-month mark each have their own characteristic patterns that help frame the six-month picture.

What the 5% review threshold means in practice, and what comes next

The NICE 5% benchmark can feel alarming if you encounter it for the first time at your six-month review. It's worth understanding what it is and what it isn't. It applies specifically to weight loss after six months at the highest dose the patient has tolerated, not six months from the very first injection. If you've spent two of those six months still titrating, the clock restarts in a meaningful clinical sense once you've stabilised at your maintenance dose.

Prescribers don't just look at a number on the scales. They consider how much of the journey was spent on lower doses, whether lifestyle changes are in place, and whether non-scale benefits (blood pressure, energy, sleep quality) have shifted. The full Wegovy guide on our site covers how these clinical decisions are framed across the treatment period.

One practical question that often comes up around this stage is whether the changes in appetite and digestion are permanent. The honest answer is that they reflect how semaglutide acts on GLP-1 receptors, an effect that continues as long as the medicine is taken. Our page on how Wegovy affects appetite and digestion goes into the physiology in plain terms.

Side effects, cost, and continuing treatment past six months

For most people, the gastrointestinal side effects that dominated the early weeks (nausea especially, and sometimes loose stools, bloating, or reflux) are much less prominent by month six. The body has had time to adjust at each rung of the dose ladder. Fatigue and headache, which can appear after dose increases, also tend to ease. That said, some people do experience a return of milder symptoms after moving to 2.4mg, particularly in the first two to four weeks. The NHS advises sticking with the current dose rather than pushing ahead if side effects are uncomfortable, and your prescriber is the right person to guide that call, not an article online.

Cost is a real consideration for anyone thinking about the longer term. Private treatment is priced per month, and six months is often the point where people first sit down to think about what continuing beyond a year might look like. The Wegovy cost guide sets out the honest picture, what's typically included in a legitimate price, what the Eli Lilly list-price changes mean, and why a prescription medicine isn't a category where the lowest quote is always the right one.

If you're six months in and wondering what comes next, the guide to Wegovy beyond six months covers exactly that. And if you're still at the earlier stages of your journey, the two-month guide is a useful reference point for comparison.
