Polycystic ovarian syndrome (PCOS) is the accumulation of underdeveloped follicles in the ovaries due to anovulation. It is is characterized by menstrual abnormalities and clinical or biochemical features of hyperandrogenism.
It results mainly from abnormal steroidogenesis that may be caused by insulin resistance leading to hyperinsulinemia.
There is increased sensitivity to androgens and the majority of women have elevated androgen levels.
A lifestyle intervention programme aimed at reducing intake of fat and calories appears to be effective for preventing the development of diabetes in high-risk Asian Indians, according to data from the Diabetes Community Lifestyle Improvement Program (D-CLIP) trial.
