|Menopausal Women Afraid of Estrogen 10 Years After the Women's Health Initiative Study (WHI)|

Ten years after the publication of two Women's Health Initiative (WHI) studies on the risks and benefits of estrogen plus progestin in healthy postmenopausal women, millions of women suffer with menopausal symptoms because they fear these hormones. The two studies scared the hell out of women and many of their doctors (see below). But over the past 10 years, newer studies have disproven many of the original findings. But harm was done for women; the fear prevented many women from taking estrogen that could have prevented terrible symptoms. I want to help you make sense of these important studies.
First, let's look at what the studies were supposed to do.
At that time, estrogen plus progestin (notice, not progesterone which is the natural hormone, but progestin, a synthetic substance that the woman's body responds to similarly to how it responds to progesterone) were being recommended for all women in menopause to lower the risk of heart disease as well as treat symptoms of menopause such as hot flashes and vaginal dryness. Postmenopausal women ages 50 to 79 (mean age 63) were given different formulations of the most common estrogen and progestin medications in use at the time.
Giving hormones to older women, they thought, would lower their risk of heart disease and so the study didn't take into account how old the women were, how long it had been since they started going through menopause, or if they were at risk for any other diseases. Hormone Therapy (HT) was considered both good and safe.
There were two hormone studies that were started about the same time. The first involved giving some 16,000 women either estrogen and progestin (Prempro - the most commonly used hormone of this type at the time) or placebo. That study was stopped 3 years early because the risks were greater than the benefits. Not only did HT not protect women from heart disease, the study reported an increased risk of blood clots, stroke, heart attack and breast cancer. There was however, an equally lower risk of colon cancer and risk of breaking your hip.
The second study also followed a large number of women. But this group of women had their uterus removed (hysterectomy) as well as their ovaries. Women who have their uterus removed do not need to take progesterone or progestin – only estrogen. Once again, the study was stopped early because the women taking estrogen had an increased risk of stroke compared to those who took a placebo. However, compared to the women in the first study who took estrogen and progestin, these women who took estrogen only didn't have an increase of breast cancer or heart disease.
Postmenopausal women threw away their estrogen in droves and endured a very challenging window of time. So challenging in fact that many of my patients who initially went off their hormones called me up and within 3 to 6 months, wanted to get back on them. But in that year after the WHI was first published, between 25% and 72% of women stopped taking HT.
Over the past decade since those initial WHI studies were done, many of their conclusions have changed. Here are my thoughts on the highlights.
If you are interested in taking estrogen and/or progesterone or want to consider it as a possible treatment for your symptoms, talk with someone who is knowledgeable about these medications. It isn't the same as going in for an antibiotic – it will take time for the health professional to understand your personal risks, explain what the benefits and risks are for you, and provide you with an explanation of your options. When I see patients for these types of discussions, I allot nearly an hour to go over everything. Make sure you find the right person to work with you.
