A friend of mine has PCOS more severely than I do. She is really hairy and has always struggled with her weight, BUT she just had a kid who is beautiful and healthy so woohoo!
I know this because one of mine is poly cystic. Usually it's both ovaries though. You can go on medication to help - an issue for young women is estrogen is required for building bone mass and reducing the risk of osteoporosis etc when you're old. So hormone regulating medication can help.
Poly cystic ovarian syndrome. Your ovum basically swell inside your ovaries. This happens normally with ovulation, but one egg at a time on either side. PCOS happens with multiple eggs at once, and they aren't released. It has a lot to do with estrogen production in your ovaries and hormones in your thyroid gland too. PCOS has symptoms like fatigue, weight gain, irritability, hairiness... Lol. It can be difficult to conceive sometimes, and many women with PCOS have irregular periods.
It is called Poly Cystic ovarian Syndrome, Multiple cysts on your ovaries, Hope that helps
