My favorite posts on Facebook are those where someone asks their followers for their opinion on which outfit to wear to a family event or their high school reunion. I love how everyone weighs in, and while they are opinionated, they are usually kind and supportive. (“Maybe go with the blue sheath instead of the peasant dress with puffed sleeves and cherries on the skirt. It looks incredible on you!”)
The posts that I struggle with are those in which someone asks for medical advice. The response is well-meaning, but the misinformation that is authoritatively given makes me a little crazy. Every once in a while, I weigh in, but it would be a full-time job to respond to every comment. This is especially true when it comes to information on menopause. As the author of many books on menopause and women’s sexual health, I feel compelled to debunk the myths that frequently pop up on social media, and with my patients, or that even your own doctor may have told you.
If you have had a blood clot, you can’t take hormone therapy.
It is true that oral estrogen slightly increases the risk of developing a blood clot and should be avoided by women who have developed a blood clot in the past. However, transdermal estrogens, which include patches, sprays, lotions and gels applied to the skin, do not increase the risk of blood clots. This includes women with a genetic predisposition to forming blood clots, such as those with a Factor V Leiden deficiency. A transdermal estrogen is preferable if there is a prior history of blood clots, a hereditary risk of blood clots, obesity, high blood pressure, diabetes, elevated cholesterol or triglycerides, liver disease, gallbladder disease, metabolic syndrome, smoking or if someone is starting hormone therapy after the age of 60.
Local vaginal estrogen, such as creams, rings, vaginal tablets and suppositories, which are prescribed to treat vaginal dryness, painful sex and urinary symptoms such as urgency and recurrent urinary tract infections, is a different story. Not one study has ever shown an increased risk of a blood clot from the use of local vaginal estrogen. There is no increased risk, and women with a history of blood clots can safely use those products.
Bioidentical estrogen is less likely to cause breast cancer than other forms of estrogen.
While bioidentical estrogen has some advantages over other forms of estrogen, when it comes to the reduction of breast cancer risk, bioidentical estrogen is not always the best.
