I'm not a doctor, but I did have them so bad I had to have my right ovary removed. It kept making cysts, I kept going to the ER from rupturing cysts. Finally enough was enough and it had to go.
Before that, I was given lots of options for treatments that did not work for me. Different hormones, naproxen (which was new at the time). As a distance athlete, it was interfering with a lot of my training. I was always careful with my diet and weight (too careful, I was anorexic) so the weight gain issue did not affect me until recently. I've had to really restrict my calories lately even though my running has not changed much.
If there's anything I could tell Whitney, I'd tell her that it gets harder as you get older. If she thinks it's hard now, she's in for a real disappointment as she ages. It's her choice to keep using PCOS as an excuse but if she remains that obese, she will be chasing a problem she won't be able to catch later on. I still feel she's hiding a food addiction with PCOS as her crutch.
