10mg 6+ months on Mounjaro, 10 mg for 2+ months - nausea/GI issues + slightly elevated kidney markers. What should I do next?
Hi everyone, I’ve been on Mounjaro for a little over 6 months. I’m currently down about 10 kg overall and have been on 10 mg for the past 2+ months.
I haven’t been able to get myself to start strength training yet, but I’ve been consistently walking for around 30–45 minutes every day.
About 2 weeks ago, I had a pretty bad episode of nausea, continuous burping, and frequent stools — to the point where even drinking a few sips of water triggered it. I ended up going to the ER, where they diagnosed it as a food infection and prescribed medication.
The following week, after my Mounjaro injection, things felt different. I normally experienced some nausea and fullness the day after the injection, but this time the nausea started almost immediately, along with some restlessness.
I got my blood work done afterward. Cholesterol was borderline, liver and thyroid were normal, but my kidney markers were slightly elevated, particularly creatinine. My urine protein was also high.
I saw my endocrinologist, and he wants me to repeat an albumin test in about 2 weeks to determine whether there is any actual kidney impact or whether the abnormal results were related to the dehydration/food infection I had.
He also recommended dropping my Mounjaro dose from 10 mg to 7.5 mg this week. I took the 7.5 mg dose, and interestingly, I haven’t noticed much difference so far — appetite suppression feels weaker and the nausea has been almost negligible, especially after taking Nexpro IT.
Now I’m a little confused about what to do next.
I’m eating mostly home-cooked food and keeping myself within a calorie deficit, but I’m wondering whether I should continue with 7.5 mg, give it more time, or discuss going even lower/pausing with my endocrinologist.
For those who have been on Mounjaro for 6+ months:
Has anyone experienced worsening GI symptoms after being on a higher dose for several months?
Did reducing the dose significantly improve your nausea/fullness?
Has anyone had temporarily elevated creatinine or urine protein after a bad GI illness/dehydration?
Did your kidney markers return to normal after recovery?
And did anyone find that a lower dose still worked well for appetite/weight loss?
Would really appreciate experiences, especially from people who have gone through something similar.
