While estrogen levels will decrease during menopause, the truth is, estrogen levels do not fall appreciably until after a womanâs last period. In fact, far more women suffer from the effects of âestrogen dominanceâ during the transition â that is, they have too much estrogen relative to progesterone. And some women can suffer from the symptoms of estrogen dominance for 10 to 15 years, beginning as early as age 35.
