during menopause, the there is a significant decrease in estrogen produced by the ovaries, according to up to date. mht works by replacing this estrogen, often combined with progesterone, that the body may no longer be producing.
but it’s not as simple as a one-for-one replacement, cardiologist and university of toronto professor dr. beth abramson explained to ctv.
“estrogen is a hormone and a hormone by definition has multiple effects on the body … and the issue with estrogen is that there is a consistently small, but important, increased risk of blood clots in the legs and the lungs. we call it venous thromboembolism. that has to be weighed against the risk of benefit to that individual patient.”
hormone replacement therapy for menopause may pose risks if started later in life
women who are a decade past menopause — roughly 60 years or older — have a higher risk of blood clotting, so mht is not recommended for this cohort.
“there have been several studies and analyses that have come out in the last few years to inform and appropriately give health-care providers the information to have a conversation with their female patients,” abramson told ctv news.
abramson is one of the authors of the new guidelines and says they are designed to give doctors, nurses, pharmacists and other health professionals the tools to better understand the therapy protocols and risks. she also says each patient has individual risks and circumstances that factor into treatment.
