I started out about a year ago taking Metformin 500mg twice a day. Then a few months later the Dr. increased my dose to 800mg twice a day. Ever since then, I have had uncontrolable diarrhea and weight loss. I am way overweight so I love the weight loss, but the diarrhea is another matter. I have also had mild/moderate abdominal discompfort too. Are these side effects common with Metformin? I have been taking Imoduim every 3 days or so to help control the diarrhea, but I am getting tired of doing that. Because if I forget to take the Imoduim, then I find myself in trouble later when I can't make it to the bathroom in time.
Metformin cause for uncontrollable diarrhea and weight loss?

Yes, diarrhea and hence weight loss is a common side effect of Metformin.
Have you talked to your doctor about this?
You may need to consider lowering the dosage or trying a slow release formulation (if you are not already).
Reducing carbohydrate and fat intake may also help try to ensure you take each dose with a meal. All the best.
