Hormonal imbalance. Most docs prescribe metformin bc ppl with PCOS are said to be insulin restistant. Metformin is a drug used to treat type 2 diabetes. Most chances if you have PCOS you are not ovulating, your producing eggs but they are not being ovulated so they form a string around your ovaries that look like cycts. You can look up metformin and infertility to find out more.
If you are overweight even moderate weight loss and exercise will improve the symptoms of PCOS . because weigth gain makes the hormonal imbalance worse. although i hate medicines and their side effects metformin may help with weight loss aswell .
Pcos is an abnormal hormonal imbalance (to much of the male hormone)
I have had it for many years, and i always was stuck at a certain weight, for years and years i tried to shift the weight only to pile it back on again.
But for a year now, i have been on a healthy diet and i do exersise every now and then.
I am down to a weight that i can control, and feel much healthier, apart from a dizzy spell here and there..
There are some good books on pcos, by collete harris, You can buy her books and the net, either at amazon or play.com.
I would recomend them, because they have helped me a great deal
