Hunger While Switching

Understanding Hunger and Progress When Switching from Mounjaro to Wegovy

At SheMed, we know that switching between GLP-1 medications can feel uncertain - especially if you notice changes in your hunger, appetite, or rate of weight loss. You’re not alone in this experience, and what you’re feeling is completely normal. It is important to recognise that your first month is all about adjustment. 

Why hunger can increase after switching

If you’ve recently moved from Mounjaro (tirzepatide) to Wegovy (semaglutide), you may notice a temporary increase in hunger or “food noise.” This doesn’t mean that Wegovy isn’t working - it’s simply because the two medications act differently in the body and your body is adjusting

Mounjaro affects two key receptors (GLP-1 and GIP), while Wegovy targets GLP-1 alone. When your body transitions from one to the other, it may take a few weeks to readjust. During this period, appetite and cravings can feel stronger until the new medication reaches steady levels in your system.

This doesn’t mean your progress has stopped

It’s common to see your progress slow down or even plateau temporarily during a switch phrase, whilst your body adjusts to Wegovy. Your strength of Wegovy may take a little time to build up again, but as your dose increases and your body adapts, you’ll find that appetite control and weight loss return gradually. If you’ve had little to no side effects since switching, that’s a really positive sign.

Remember, these medications are designed for long-term use. The key to success is steady progress - not quick fixes. 

Keep Your Schedule Consistent 

We know it can be tempting to request to increase your dose when hunger returns, but we strongly recommend not requesting to do so. Increasing your dose mid-pen can raise the risk of side effects such as nausea or stomach upset.

Instead, stay consistent with your current plan and allow your body the time it needs to adjust safely. If you haven’t experienced any side effects so far, that’s a really positive sign that your body is tolerating the change well.

Your refill questionnaire helps guide your next steps

Each time you complete your refill questionnaire, your responses go directly to our clinical team. They review your feedback carefully, including any notes about hunger, cravings, or changes in weight, to determine whether your dose or treatment plan needs adjusting.

If you’re feeling frustrated or unsure about your progress, please include as much detail as possible in your next questionnaire. This helps your clinician understand your experience and tailor your plan for the best possible results.

The bottom line

Feeling hungrier or noticing slower progress after switching from Mounjaro to Wegovy doesn’t mean your treatment isn’t working - it’s part of your body’s natural adjustment. Your results will continue to build as you move through your doses, and our team is here to support you every step of the way.

At SheMed, our priority is your safety, comfort, and confidence - ensuring every stage of your journey feels supported, understood, and guided by science.
