I believe I've failed to mention this in previous posts, but the most recent post about Depo-Provera causing PCOS got me to thinking about it:
I think Megace ES caused my PCOS.
Unfortunately, I didn't know that Megace ES was an extremely potent synthetic progesterone (progestin). It was prescribed to me to "increase weight and appetite." (I was skinny and my doctor didn't like it).
Here's the story: When I first began having PCOS symptoms, it was the day following a dose of Megace ES. Megace ES is a liquid medication used to stimulate the hypothalamus to make you hungry. It is commonly given to cancer patients to help with their appetite.
The reason why *I* was on it was because my stupid doctor didn't like the fact that I was a bit underweight (HA! Not anymore, so it must have worked. :eyeroll

. I tried explaining to him that I've always been underweight, but he made me feel bad about myself, so I took the Megace ES.
If I had any idea that Megace ES is actually an extremely potent synthetic progestin I would have never touched the stuff with a 40ft pole!!!!
the day after I took the Megace I had a period (withdrawal bleed) for a week, and was quite upset because I already HAD aperiod that month. When I called my doctor he said I just had a double period, nothing to worry about, and that it probably wouldn't happen again.
Needless to say 2 weeks later I picked up the Megace ES once again when I wanted to give it another go.
Lo and behold, another period (withdrawal bleed).
By that time I just *knew* the Megace had something to do with it, but never understood why.
The following 3 months after those 2 doses of Megace ES, I had about
8 periods.
Then boom, PCOS sympotms soon followed including cystic acne, perpetual PMS, fatigue, bloating, weight gain, and then finally a complete cessation of periods.
Just figured I'd share...
