So, my sister thinks she might have PCOS (polycystic ovaries), and she seems to be blaming it on her several month eating disorder episode. She thinks she made herself sterile. That doesn't make any sense, and I don't see how that could be possible. I looked up the consequences of eating disorders, and I saw a lot of cardiac, etc symptoms, but nothing reproductive. With that aside, I KNOW it already runs in the family. My grandmother had it, and my aunt has it. I just don't want her to feel guilty when she doesn't need to. She doesn't need another thing to be upset about.
