Ok, so we all know we have PCOS but how many of us know what causes it? There is a health article about this topic but not everyone has seen it so i thought why not post it here!?
Picture of a Polycystic Ovary.
In each menstrual cycle, follicles grow on the ovaries. Eggs develop within those follicles, one of which will reach maturity faster than the others and be released into the fallopian tubes. This is "ovulation". The remaining follicles will degenerate.
In the case of polycystic ovaries the ovaries are larger than normal and there are a series of undeveloped follicles that appear in clumps, somewhat like a bunch of grapes. Polycystic ovaries are not especially troublesome and may not even affect your fertility.
However, when the cysts cause a hormonal imbalance, a pattern of symptoms may develop. This pattern of symptoms is called a syndrome. These symptoms are the difference between suffering from polycystic ovary syndrome and from polycystic ovaries.
So you can have polycystic ovaries without having PCOS. However, nearly all women with PCOS will have polycystic ovaries. Polycystic Ovary Syndrome is the name given to a metabolic condition in which a woman will have polycystic ovaries, along with a certain pattern of other symptoms that reflect imbalances in reproductive and other hormones.
We referred to polycystic ovarian syndrome as a “metabolic" disorder. By this we mean that there are numerous factors in basic body processes that have gone awry. Because your body is a unified whole, a problem or dysfunction in one area causes dysfunction in other areas. Polycystic ovarian syndrome is a dysfunction that is related to your whole body, not just your ovaries.
Let’s define some terms:
"Syndrome" simply means a set of symptoms that occur together, in a pattern.
"Polycystic" means there is an accumulation of incompletely developed follicles (cysts) in the ovaries.
"Polycystic ovarian syndrome" refers to a health disorder where there may be many cysts in the ovaries, accompanied by a distinctive pattern of symptoms.
"Metabolic" refers to the physical and biochemical processes required for the body to function.
"Polycystic ovary syndrome" is the name given to a metabolic condition in which a woman will have cystic ovaries, along with a certain pattern of other symptoms that reflect imbalances in reproductive and other hormones.

Polycystic ovary syndrome is a dysfunction that is related in some way to your whole body, not just your ovaries.
There is disagreement and uncertainty as to what causes polycystic ovarian disease. Polycystic ovaries and polycystic ovary syndrome have been associated with one or more of these factors:
Genetic predisposition.
Insulin resistance or hyperinsulinism (high blood levels of insulin).
Obesity.
Hyperandrogenism (excessive production of male hormones).
Abnormality of the hypothalamic-pituitary-gonadal axis (organ/hormonal disorder).
Environmental chemical pollution (hormonal disruptors)
Food adulterantion (excitatory amino acids, for example)
Chronic inflammation.
Some of these causal factors may also be consequences of polycystic ovary disease. In other words, we have an amazingly complex network of interacting variables, each of which influences the other. Polycystic ovarian syndrome is not a simple disease with a single cause.
I really question "Obesity" as a cause (I know that you did not come up with it) I was never fat until I had PCOS and never started being able to loose the weight that I had gained until after being treated for PCOS. Thanks to PCOS, I am also pre-diabetic 
I think that my mother was PCOS and never diagnosed with it and she would up Type II Diabetic, with no family history of diabetes.
I do blame it for not being able to lose weight, well that & the fibro 
My internet broke so i havent been on for a couple of days, theres so many posts for me to read
