Weight Loss Drug Mounjaro Linked to Endometriosis Misdiagnosis
14 Sep
Summary
- Caitlin Sorby lost nearly 8st on Mounjaro for presumed PMOS symptoms.
- Her symptoms persisted, suggesting a possible endometriosis diagnosis.
- She spent £300 monthly on medication, now hopes to save money.
A 31-year-old woman's extensive weight loss journey, fueled by the drug Mounjaro, has taken an unexpected turn. Caitlin Sorby lost almost 8 stone, reducing her weight to 8 stone 12 lbs, after being diagnosed with presumed PMOS in July 2024. Her GP referred her to a weight management program, and she began Mounjaro in March 2025, which led to consistent weight loss.
Despite her significant physical transformation and improved energy levels, Sorby's severe pelvic pain and irregular periods continued. These persistent symptoms prompted a medical review, revealing that she might actually have endometriosis rather than PMOS. This potential misdiagnosis has left her feeling that her efforts were "all for nothing."
Sorby spent approximately £300 monthly on Mounjaro and is looking forward to discontinuing the medication, which she hopes will alleviate financial strain. Endometriosis, a condition where womb-like cells grow outside the uterus, can take years to diagnose in the UK. Sorby is now focused on maintaining her current weight and managing her health going forward.
