medication and weight loss

Amy_FeathSaorsa

Hi
I currently take 3 medications/6 tablets a day for different conditions. I have PCOS and therefore take metformin which in theory should help me lose weight however I'm still gaining weight despite counting my calories and carb intake. Its been suggested that my other medications are causing my weight gain and have been replaced with alternatives to try to combat this.
Has anyone else experiences this, especially when taking metformin? How did you combat it?
Thank you
