There is growing evidence that mood disturbances, mostly severe depression, are common in PCOS women , in whom impaired quality of life from body image concerns cause fatigue, sleep disturbance and changes in eating habits.
The exact cause of PCOS is not clear. Many women with PCOS have insulin resistance. This means the body can't use insulin well. Insulin levels build up in the body and may cause higher androgen levels. Obesity can also increase insulin levels and make PCOS symptoms worse.
