I don't have PCOS, insulin resistance (that I know of) or diabetes. However my doctor prescribed me Metformin to help with weight loss. I was thrilled!
However I've been taking Metformin for a number of weeks now and I seem to be gaining weight. Big ol' WTF?
I do have hypothyroidism and my TSH has been stable for around 18 months. Apart from that my weight gain is unexplained. I have a small appetite and reasonably healthy diet (ie. lots of veggies, little to no junk).
I've read that common side effects of Metformin can be nausea and diarrhea (which is sometimes attributed to higher rates of weight loss), however it seems to be doing the opposite to me (TMI - mild constipation).
What the heck? Has anyone else experienced this while taking Metformin?
