Is It Safe to Use GLP-1's Like Mounjaro for Weight Regain After Bariatric Surgery?
My experience using GLP-1's with my Weight Regain Ladies, after Bariatric Surgery.

Weight Regain After Bariatric surgery:
Weight regain after bariatric surgery can feel confusing, frustrating, and even shameful, but you're not alone. As a GLP-1/ Bariatric dietitian and Emotional eating coach with over 30 years of experience, I’ve worked with hundreds of women who’ve felt lost after regaining weight post-surgery.
Many come to me asking the same question:
“Is it safe to use GLP-1 medications like Mounjaro,Wegovy or Ozempic to help with weight regain after WLS?”
The short answer is: YES, when used correctly, and with my support. But there’s a lot more to it than just taking an injection.
Why You Regain Weight After Weight Loss Surgery:
First it's important to understand why you may regain weight after having weight loss surgery. In my experience it comes down to the reliance on the surgery to do all the work. The reality is that Bariatric surgery is merely a tool, however when you've struggled with your weight for most of your life and tried every FAD diet out going, you become programmed for instant results and who could blame with the cost of surgery. After the surgery you have a honeymoon period where you're losing weight with ease and this lures you into a "false sense" of security... until the weight loss slows down and the long stalls hit. Suddenly you feel let down by the surgery and begin to lose faith as the hunger returns. It's a very unsettling place to be if you don't have support. And most of the women I support with regain have had either no support or very little.
Why Women May Consider GLP-1s After Surgery
GLP-1 medications such as Mounjaro, Ozempic, and Wegovy were originally developed for managing diabetes, but their appetite-suppressing effects have made them popular tools for weight loss. These medications work by slowing down digestion, reducing hunger hormones, and quietening the mental food noise that many women struggle with once they begin to regain weight after surgery.
My Approach: Micro dosing for Maximum Impact
The women I work with have learned that they need support and aren’t looking for a quick fix, they want clarity, control, and to feel like themselves again. That's why I use a micro dosing approach, where we stay at very low doses, typically no higher than 2.5mg of Mounjaro.
This helps to:
- Take the edge off hunger
- Reduce cravings and food noise
- Recreate that focused, empowered feeling during the honeymoon phase
Once we’ve quietened the food noise, we go deeper working on nutrition, movement, and emotional eating. Because injections might lower your appetite, but they don’t teach you how to eat well, cope with stress, or build sustainable routines.
It’s Not Just About the Jab
GLP-1's are a tool, not magic wands. Without guidance, it’s easy to under-eat, lose muscle, or fall into restrictive patterns that can harm your long-term results.
That’s why my one to one support includes:
- Post-op meal plans that nourish, not deprive
- Step By Step Guidance on movement and exercise that feels achievable
- Deep work on emotional triggers and self-sabotage patterns
- Ongoing motivation and mindset support to rebuild trust with your body
Most women I support don’t stay on GLP-1's long-term. The goal is to create space and clarity, then build solid, lifelong habits.
Is It Safe for You?
GLP-1's can be a safe and effective option for weight regain, especially when you're supported by someone who understands both bariatric recovery and the complexity of emotional eating. You will need to meet criteria i.e BMI>30 or BMI>27 with a co morbidity like type 2 diabetes, hypertension or heart disease.
If you’re feeling stuck, overwhelmed, or unsure what to do next, I invite you to explore my GLP-1 Toolkit a step by step digital guide to fuel your body, create healthy habits and overcome emotional eating. It walks you through the steps I use with my one to one clients.
