Why this topic matters

Incretin medicines can affect appetite, weight, and blood sugar, all of which are important in pregnancy planning. The safest approach is to plan ahead rather than stopping suddenly without a strategy.

Pregnancy

If you are pregnant or think you might be, seek medical advice promptly.
Discuss medication timing and alternatives with a clinician who can consider your full history (including diabetes status).

Trying to conceive

Tell your prescriber early if you’re planning pregnancy (including IVF).
Ask about how long to stop before trying to conceive, and how to manage appetite and weight during that transition.

Breastfeeding

Breastfeeding decisions involve balancing infant safety, maternal health, and the feasibility of weight‑loss plans. Discuss this with your clinician to decide the safest approach.

If your goal is metabolic health pre‑pregnancy

Focus on nutrition quality, protein intake, and strength‑building habits you can maintain.
Treat sleep and stress as part of the plan (they affect appetite and insulin sensitivity).
Work with a clinician to choose a safe approach for your timeline.
