Swapping from 7.2 to Mounjaro
Stats: 5'7" | SW: 121 kg (266 lbs) | CW: 108 kg (238 lbs) | Total loss: 13 kg / ~31 lbs in 7 months | Provider: SheMed (UK)
I started Wegovy in mid-January this year and I'm really proud of what I've achieved so far. This is the first time I’ve had genuine success with weight loss, and I’ve had some incredible non-scale victories (fitting into smaller dress sizes, feeling fitter, etc.).
Throughout my journey, my weight loss pattern was usually “loss, loss, loss, gain, then loss again when upping the dose.” I moved up every 4 weeks until reaching the highest maintenance dose in June of 7.2mg.
However, over the last 7–8 weeks, I’ve hit a complete stall:
The Stall: I've been stuck in a loop of losing and regaining the exact same 1 kg (2.2 lbs) over and over.
Routine: In June/July, I started hitting the gym consistently (3–4 classes a week) and walking 8,000+ steps most days.
Calories: Eating roughly 1,600–2,000 kcal to fuel my activity (at 5'7", 1,200 felt unsustainable and too low as recommended by TDEE).
Perception: Even though I know the "paper towel effect" is real, I can’t see the difference in the mirror yet, and no one has commented, which adds to the mental frustration. I can buy something’s in smaller sizes but this isn’t consistent so it’s not a full “I’ve lost a dress size”
Side Effects at Top Dose:
I was lucky with minimal side effects early on, but the top maintenance dose hit me hard - especially been given the all in one 7.2 mg pen (no more 3 x 2.4 mg)
- Severe stomach pain and non-stop diarrhoea
- Awful sulphur burps
- Skin sensitivity: to the point where fabric simply brushing against my arms and body felt painful and tender.
The Move to Mounjaro (MJ):
Given the plateau, the intense side effects, and the cost difference (MJ is nearly £50/month cheaper with my provider then max dose Wegovy), I’ve decided to switch to Mounjaro. They are starting me at 5 mg due to my prior tolerance on higher-dose semaglutide.
For those who switched from Wegovy to Mounjaro (especially starting around 5 mg after a plateau), how did you find the transition? Did it help break your stall or ease side effects?
Any advice or guidance would be helpful!
