I've just had my 1 year mounjaro anniversary. I've not had any pancreas related side effects.
Side effects I have had: I have had a loose tummy and / or felt nauseous at times, mostly in the day or two after jabbing in the first few weeks, then when going up a dose whilst my stomach adapts. The first three months, I was incredibly tired, but that did get better. I've had fairly significant hairloss, but luckily, I have very thick hair so it wasn't noticeable and it is now growing back. I've also recently started getting really sensitive skin on my wrists and inner arms, it's hard to describe but it sort of feels like a friction burn, again in the first day or two after jabbing. Ive also been really really cold.
That said, I've never had all those things at once and they are all manageable, it's never been enough for me to even think twice when weighed against the benefits I've seen. I've lost over 5 stone in a year and now have a BMI in the healthy range. It's changed my life in so many ways. Just a one example, my 6 year old has been teaching me to do flips on her trampoline for the last few months, we've had such a laugh together, a year ago I would have simply refused to try.
I think the best advice if you do want to give it a go is to be completely open and honest with your prescriber and contact them to discuss if you have any concerns.
Good luck 👍
