Question:
Female, 40 years old, unknown subtype
My daughter’s GP, and she herself, want to try Mounjaro injections for 6 months. She will be closely monitored by her nurse, her GP, her care team and family. She currently does not appear to have issues with gastroparesis but I want to prevent them by changing her diet to the low fiber, low fat and frequent snack one recommended in the article “Hidden Gut Issues” on this website. Do you have any new information and/or advice on the Mounjaro or the prevention of digestive issues?
Nurse Lynn’s Response:
While your daughter has strong monitoring in place, it’s important to note that GLP-1 medications are considered high-risk for individuals with Prader-Willi Syndrome (PWS) due to their unique gastrointestinal vulnerabilities. Currently, there is one study underway in the United States evaluating the efficacy and safety of this class of medication in individuals with PWS, and hopefully more research will follow.
It’s clear that you’re doing your homework, and your instinct to proactively adjust her diet before any issues arise is absolutely appropriate. Based on current expert guidance, it is essential to have a thorough discussion with her GP and care team about the lack of long-term safety data and the very real risks associated with GLP-1 use in people with PWS.
If you and her healthcare provider decide to proceed with a GLP-1 medication, be alert for warning signs that may indicate serious complications, such as:
- -Complaints of abdominal fullness or bloating
- -A firm or distended abdomen, or refusal to eat
- -Drooling, pale skin, or episodes of fainting
- -Sudden behavioral changes or lethargy
These symptoms may be early indicators of gastric necrosis or rupture—a life-threatening emergency in individuals with PWS—and require immediate medical attention.
