Polycystic ovary syndrome (PCOS) is an endocrine disorder that affects approximately 5% of all women. It occurs amongst all races and nationalities, is the most common hormonal disorder among women of reproductive age, and is a leading cause of infertility. The symptoms and severity of the syndrome vary greatly among women. While the causes are unknown, insulin resistance, diabetes, and obesity are all strongly correlated with PCOS.
Where PCOS is associated with overweight or obesity, successful weight loss is probably the most effective method of restoring normal ovulation/menstruation, but many women find it very difficult to achieve and sustain significant weight loss. Low-carbohydrate diets and sustained regular exercise may help. Some experts recommend a low Glycemic index diet in which a significant part of the total carbohydrates are obtained from fruit, vegetables and whole grain sources.
