Book a ConsultationIn recent years, Mounjaro (tirzepatide) and other GLP-1 medications have become widely used for weight management. As more patients reach their weight-loss goals, many start exploring plastic surgery to refine their results, address loose skin, or enhance body confidence.
However, taking a GLP-1 medication does come with important considerations when planning any surgical procedure. Proper preparation helps ensure your treatment is safe, smooth, and predictable. Here’s what patients should know.
Understanding Mounjaro and Its Effects
Mounjaro works by:
- Slowing digestion
- Reducing appetite
- Helping regulate blood sugar
- Supporting weight loss
Because it affects the gastrointestinal system, it may also influence fasting before surgery, nausea, and anaesthesia considerations. That’s why it’s essential that your surgical team knows exactly what medication you’re taking and how long you’ve been on it.
Why Your Surgeon Needs to Know
Anaesthetists and surgeons increasingly request information about GLP-1 medications because:
1. Slower gastric emptying may increase risk during anaesthesia
Patients on Mounjaro can have food remaining in the stomach for longer than usual, even after the standard fasting window. This is important because retained stomach contents can increase aspiration risk during general anaesthesia.
2. You may need to pause the medication before surgery
Many surgical teams now ask patients to temporarily stop Mounjaro before their procedure.
The timing varies depending on:
- The type of surgery
- Your medical history
- The dose you’re on
- The anaesthetist’s protocol
Your surgeon and prescribing clinician will guide you on the safest plan for you.
3. Surgery results may be more predictable after weight stabilises
If you are still actively losing weight, results of certain procedures—such as tummy tucks, breast surgery or body contouring—may change as your weight continues to drop. Many surgeons recommend waiting until weight has been stable for a period of time.
How to Prepare Safely
Here are general, non-medical preparation guidelines your clinic can share with patients:
✔ Inform your surgeon early
Tell your surgical team about all medications, including Mounjaro, supplements, and over-the-counter products.
✔ Follow your surgeon’s and prescriber’s advice on pausing the medication
Only stop or adjust your medication if you are advised by the professionals managing your care.
✔ Allow extra time for consultation and planning
Patients on GLP-1 medications may require:
- Additional fasting instructions
- Extra anaesthetic assessment
- Slight adjustments to the surgery timeline
✔ Stay well-hydrated and nourished
Mounjaro can reduce appetite, so it’s important not to enter surgery depleted. Proper nutrition supports healing and recovery.
✔ Ensure your weight is stable
This helps your surgeon plan the most accurate results, especially for contouring procedures.
✔ Plan for recovery support
Healing after surgery requires patience and rest. Include time off work, help at home, and post-op garment wear in your planning.
Why GLP-1 Patients Often Seek Surgery
Many patients considering surgery after weight loss describe wanting:
- A more balanced body shape
- Removal of loose skin
- Better comfort and confidence
- Clothing that fits well
- A physical result that matches their hard work
Plastic surgery can be an empowering step, helping patients feel fully at home in their new body.
The Bottom Line
Taking Mounjaro doesn’t prevent you from having plastic surgery — it just means you need thoughtful planning and the right medical guidance.
With clear communication, proper preparation, and a tailored plan, patients can safely move forward toward the results they’ve been working so hard for.
