From the second day of taking metformin I got constipated. They took me off for a week, then had me on a timed release kind, but still constipated. Now I am off any kind of med and I'm fine.

I've been on it a week. For the first 5 days I had horrible stomach cramps and diarrhea, the last 2 days constipation. Nothing else had changed medication- wise or with diet. It has to be the metformin.

Interestingly, I was prediabetic for years because of this metabolic syndrome. I was taking berberine for the Sunstone (study being done in Mexico). I ran out about a month ago, and that's when I started getting super slept after meals. Went in and was DX'd with diabetes. If this medication continues to be this harsh, in going back to berberine. It also helped my cholesterol tremendously.

They still have not put me on anything, but I think the next time I go for A1C test, I will go on a low dose of insulin. I have a hard time with meds, I ended up in ICU for a week because of an antibiotic. My body has changed over the years, and myself and Doc. are nervous putting me on any new pills. So tell them about me next time you go to doctors.

I have been on metformin for 5 months and have been constipated for 4 months. Trying to get DR to change, but he seems to think metformin does not cause it.

The most common side effect of metformin is diarrhea. regardless of the cause, you can treat the constipation the same way (i.e. increase fiber intake or use fiber supplementation, take a stool softener such as docusate). If you have not had a bowel movement in sometime, you can resort to more immediate measure such as milk of magnesia, miralax, senna, bisacodyl, etc. all available in the pharmacy.

I asked my Dr the same thing wehn i started it. She said she hasn't heard that being a side effect. I stuck it out for a week and the opposite most common side effect happened. Now all good, my body adjusted

I thought it would go away but after a month and a half, it was still bad. I assumed I'd get used to it. But never did. So after 3 months of misery I was taken off of it.

I have never heard of metformin giving someone constipation, it's usually the opposite. I do know that pain meds can often cause it. Could it be something else you are taking or maybe you just didn't eat enough veggies?

I had been on Met for about 10 years before I had to switch to insulin due to kidney issues. I have heard of diarrhea due to Met but not constipation. However since not every input (food, drink, meds) is metabloized the same way by differnt people, I could believe it. I had no problem with my digestive tract when I was on Met.

God's best to you
