i have not experienced yeast infections. i cannot lose weight even when i go to the gym. have you had your glucose levels tested? i have noticed an extreme sensitivity to sugar. mirena can mess with your glucose levels. if your glucose levels are high then you can get yeast infections easier and often. i dont have acne, but my hair is always oily. i never had that problem in my life. if your glucose levels are off it can affect your weight too.
