Dr. Heward explains if women not taking hormones age faster than women taking hormone replacements.
It’s a hard question to answer. It's difficult to answer a question about aging faster, particularly for someone like me who is in the business of trying to develop biomarkers of aging and actually measure aging. I can tell you pretty much unequivocally, we don’t know how to measure aging. We don’t know what aging is, but based on a number of biomarkers of aging and health risks, what I can tell you unequivocally is that women who are not on hormone replacement therapy decline functionally in many ways measurably faster than women who are on hormones and derive the benefits for that.
So in terms of functional capacity, hormones preserve youthful function, and the absence of hormones accelerates the loss of that function. To the extent that loss of function is aging, and it is, then hormones slow the aging process.
