Ok I have been on metformin hcl ER 500 mg once at night. It has been almost two weeks since I started the medication.....for the past couple of days I noticed something in my bowel movement.....its in my morning stool it looks kinda orangish an kinda like a small carrot that has white stuff in the middle. I know this is totally disgusting but I need some advice! Could it be the metformin being released in my stool?? If so, does that mean I'm not getting my medication like I should?? My sugar levels have been alright, sometimes up to 140 after I eat a meal that I shouldn't but other than that ok. What should I do???!!! I haven't noticed any other aide effects but occasional loose bowel movements.
