Jot down a few questions to make the most of your conversation.
Will I gain weight if I stop taking weight loss jabs?
It is possible to regain weight after stopping weight loss jabs such as Wegovy, Saxenda or Mounjaro. These medicines can help reduce appetite and support smaller portions while you are taking them. If the underlying habits are not maintained, weight often starts to creep back.
That does not mean everyone will put all the weight back on. Some people keep part of their weight loss, especially if they have built stronger routines around food, activity and sleep. But many people find that their appetite increases again once treatment ends.
Why weight regain can happen
Weight loss jabs work by affecting hunger and fullness signals in the body. When the medicine is stopped, those signals may return to how they were before. This can make it easier to feel hungry more often and harder to feel satisfied after meals.
Your body may also respond to weight loss by slowing metabolism slightly and increasing appetite. This is a natural survival response, but it can make it easier to regain weight. For many people, this is one reason long-term weight management can be challenging.
Can anything help prevent weight gain?
Yes. Keeping a balanced eating pattern can make a big difference after stopping treatment. Regular meals, enough protein, plenty of fibre and fewer ultra-processed snacks can help with fullness. Planning ahead can also reduce the chance of overeating when hunger returns.
Physical activity is important too. You do not need intense exercise to benefit; walking, cycling, swimming or strength work can all help. Good sleep and managing stress may also support appetite control.
Should I stop my treatment suddenly?
You should not stop weight loss jabs without speaking to your prescriber or GP first. They can explain whether you need to reduce the dose gradually or whether it is safe to stop. They may also discuss whether another plan is needed to help keep the weight off.
If you have side effects, are concerned about cost, or feel unsure about continuing, get medical advice rather than making changes on your own. A clinician can help you weigh up the benefits and risks. They can also check whether the medicine is still suitable for you.
What should I expect in the UK?
In the UK, these medicines are often part of a broader weight management plan, not a standalone fix. NHS or private treatment usually works best when it is combined with lifestyle support. That means stopping the jab may be less likely to cause regain if you have sustainable habits in place.
If you are worried about regaining weight, ask for a follow-up plan before you stop. A realistic maintenance strategy can make the transition much easier. The key is to think beyond the injections and focus on long-term support for your health.
