[|Human|] I am taking metformin for pcos. Since i been taking it pretty much every stool has this oval either off white or translucent shaped object that comes out. I have never seen this in my stool except when i take the metformin. What is this and should i be concerned?
[|AI|]  Hi, Commonly used in the treatment of type 2 diabetes and polycystic ovarian disease, metformin is well tolerated by most of the patients however its common side effects include abdominal cramps, diarrhea, deficiency of vitamin B12 and a serious condition called lactic acidosis. Based on the history given the oval-shaped white or translucent shaped objects in the stool appear to be the outer shell of the undigested tablet of metformin.  The actual Chat Doctor.  This is a harmless effect which can be minimized by swallowing whole table without crushing, dividing or chewing it. Hope I have answered your query. Let me know if I can assist you further. Take care
