polycystic ovary syndrome
"I was on yaz for three years. I am really torn on how I feel about it. I am an average weight non smoker. I am on birth control for ovarian cysts, not to prevent pregnancy. At first yaz was great. No periods, at all, but some bleeding after sex. I lost 10 lbs immediately, mostly just water weight, and my pms/pmdd was so much better. The negative part is the extremely painful breasts, low libido, a blood clot, binge eating, price, and eventual negative mood changes. I have finally connected yaz to two whole years of horrible light headed/dizzy spells, of which I originally blamed my antidepressant. I am now getting off of yaz to and going back on my antidepressant. I cannot yet prove it was the yaz but I do see dizziness as a side effect."
