Consequently, perimenopausal and menopause of women are often exposed to unpossed estrogen for long periods, and this exposure can lead to endometrial hyperplasia, Osteoporosis, Insomnia, Schizophrenia, Panic disorders, obsessive- compulsive and bipolar disorders. In United Kingdom, 1.3 million Women reach menopause annually. Although most women transition to menopause without experiencing psychiatric problems, an estimated 20% have depression at some point during menopause.
