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 experts have not come to a conclusion about the cause of PCOS, but the condition is marked by several hormonal imbalances, including the overproduction of estrogen and androgens by the ovaries. These excess hormones can lead to obesity, acne, the growth of facial hair, as well as the loss of hair from the scalp.
