Reply #68: The causality on polycystic ovary syndrome is the reverse; if you're heavy, you're more prone to it. [View All]

If you lose weight, symptoms decrease or disappear, though some thin women get pcos too.

Insulin resistance & high circulating levels of insulin appear to be causal. The most typical cause of insulin resistance = excess weight/low activity.

Losing weight/increasing activity/bariatic surgery resulting in weight reduction/diabetes drugs which improve insulin sensitivity have shown high effectiveness in treatment.

autoimmune disease is the body attacking itself. there's no evidence of this in pcos to my knowledge.
