Well, a lot of the plastics and other chemicals in our environment are endocrine disruptors -- i.e. they affect our endocrine system = PCOS!
Here's a
list of scholarly articles on it.
I wouldn't doubt that there are some PCOS cases that fall in this category and are caused by chemicals and other environmental factors.
For myself, I know there is diabetes in my family, as well as thyroid issues, and other family members with PCOS. For me, it's genetic.
My lab results have shown it's a question of my insulin not working properly.
I eat organic (and have been doing that for a long time) as well as using less plastic in my life (water bottles included, no tupperware in the microwave that kind of stuff) and it hasn't made my weight loss any easier or faster.
If I keep my carbs low, and my calories low, I lose weight. There's no other secret for me, unfortunately.
It'd be nice to find a way to switch my weight loss into a faster mode, but I don't see what other changes I can make!
