Definitely common if you start at a too high of a dosage. I talked with my doctor about it at my last exam. I told her I stopped taking it because of the diarrhea. I was resistant to taking it again, even though she was urging me to try it again.
Instead, she started me with 1-500 mg tablet in the evenings for 2 weeks, then adding 1-500 mg tablet in the morning. She said to try that for a few weeks and see if I can up the dosage on one end or the other to the full dosage (1000mg). I think that's the problem: starting at too high of a dosage. I've been on the 2 tablets a day for about a week now and no digestive issues so far!
Fatty foods are another huge culprit, so I find it easier to stick to my diet! :)
It's common to get the diarrhea if you eat really fatty foods. I can count it like clockwork - if I eat a greasy meal with my metformin, 3-4 hours later I am in massive painful diarrhea mode. I hope your doctor slowly got you up to that dose, 1500mg all at once is a giant leap!
Lost 65lbs in 15 months to get healthy and in top shape to try to get pregnant, and succeeded! Had our first baby in February 2013!
I only gained 32lbs in my pregnancy (and immediately lost half within a few weeks of his birth). April 1st is my full restart date.
I would ask your pharmacist or doctor. I started metformin for pcos in October. They started me on only 500mg a day, and are working me up so I don't have that issue. It does however make me more regular, I found it does seem to mess with my bowels more if I eat fatty foods though.
Interested in joining a team, I lead the following teams:
I just found out in September that I have PCOS and was started on Metformin 1500 mg a day. Well my doctor told me I would more than likely end up with diarrhea, which I did. It's now been 4 months and I still have it. Is this normal?
