1. Hormone Therapy Beyond the “Window“: Dispelling Age Myths

It's time to debunk the myth that hormone therapy is only for younger women. Older women, especially those beyond the so-called 'ideal' window, can still benefit from treatment. Let's shift the focus from age prohibition to the potential benefits of hormone therapy.

It's time to stop pretending that there's some magical age where hormone therapy (HT) suddenly becomes too dangerous to consider. The science doesn't support that fear-based messaging, and in fact, it tells a very different story.

For decades, women who were more than 10 years past menopause were told they were 'too late' for hormones (this usually means estrogen, implying that progesterone and testosterone don’t matter). You are too old. Past the window. Told that hormone therapy was 'only for young menopausal women' and 'not safe after age 60.' But let's be clear: those warnings were based on broad, outdated interpretations of the WHI study - a study that used oral conjugated equine estrogens and synthetic progestins (no longer the gold standard) in women who were already decades into menopause, many with underlying conditions. As the years went on in that study, the 'risks' didn't hold up - most strikingly, the risk of stroke.

The actual truth? It tells a different story. A safer, more nuanced one. Especially when discussing transdermal estradiol, the other hormones, and individualized care.

Every year, about 1.3 million American women enter menopause—the stage of life when your estrogen levels diminish and your periods stop completely. It’s a natural part of aging and nothing to fear.

That said, the symptoms of menopause—including hot flushes, low sex drive, trouble sleeping, weight gain, UTIs and vaginal dryness, brain fog, heart palpitations, muscle and joint aches, and mood changes—can be miserable and debilitating. You also lose the health benefits of estrogen itself, like heart and brain protection, says Avrum Z. Bluming, MD, a hematologist and medical oncologist who has spent decades investigating the benefits of estrogen. Women can avoid many of these problems with one treatment: hormone replacement therapy, or HRT. Alternatively called MHT, for menopausal hormone therapy, HRT refers to the combination of estrogen and progesterone given to women who still have their uterus; estrogen alone is given to women who have had a hysterectomy.

Unfortunately, HRT remains controversial, due mostly to the results of the decades-old Women’s Health Initiative, the largest study done on the health of postmenopausal women in the United States. In 2002, findings from the WHI were released suggesting that women on HRT had greater risks of heart disease, stroke, dementia, and, scariest of all, breast cancer; as a result, millions of women of menopausal age either quit or avoided it at all costs. Subsequent studies have walked back these claims, but many women remain gun-shy about taking estrogen. The fallout has been enormous: Among menopausal women in the United States, just under 5 percent are currently on HRT, and it’s been estimated that between 2002 and 2012, over 90,000 American women died prematurely, mainly from heart disease, as a result of avoiding HRT.
