If you’re going through menopause, or have
been there, you’ve probably experienced some
common symptoms of this inevitable life
milestone: hot flashes, night sweats, headaches,
mood swings and maybe even depression.
Hormone therapy—which comes in
pills, patches and topical creams—is widely
known to provide symptom relief, but many
menopausal women are unsure about taking
hormones because they’ve heard mixed
reviews about the safety of long-term use.
According to Elizabeth Shaw, Ph.D.,
OGNP, a board certified OB/GYN nurse
practitioner with Pinehurst Surgical
Women’s Care Center, the widespread
decline in hormone therapy began in 2002,
after the National Institutes of Health
(NIH) abruptly halted a major long-term
clinical study designed to test the effects
of postmenopausal hormone therapy, diet
modification, and calcium and vitamin D
supplements on heart disease, fractures,
and breast and colorectal cancer.
The study, called the Women’s Health
Initiative (WHI), examined two types of
therapy: an estrogen-plus-progestin study
of women with a uterus and an estrogen alone
study in women who had their uterus
removed. In both hormone therapy studies,
researchers randomly assigned women
either to the study medication or placebo.
More than 16,000 postmenopausal women
participated in the studies.
“The WHI was halted prematurely after
five years, because the findings suggested
hormone therapy did not protect against
heart disease as we once believed,” says
Shaw. “On the issue of breast cancer and
hormones, researchers also saw a small, but
not statistically significant, increase in the
risk of breast cancer among women taking
combination therapy, which also led to the
early termination of this study.”
Researchers also found an increased risk
of blood clots, stroke and dementia in
the women who took the combination
estrogen-progestin pill. Faced with clinical
evidence about these potential health
hazards, the medical community began to
reevaluate its use of hormone therapy in
postmenopausal women.
William Terry, M.D., a board certified OB/GYN specialist with Pinehurst OB/GYN
Associates, believes the WHI, although well
intended, was not well designed.
“The media gave the WHI more credibility
than was due,” he says. “The study
enrolled women who were not appropriate
candidates for hormone therapy and
excluded women with mood swings, hot
flashes and other problematic menopausal
symptoms. The wrong group of women
was studied. It’s like evaluating a blood
pressure medication but excluding people
with high blood pressure.”
In October 2004, after reviewing WHI findings, the American College of Obstetricians and Gynecologists issued a task force report about menopausal hormone
therapy:
… It’s important to keep in mind that the WHI was designed to investigate whether or not hormone therapy or estrogen therapy could prevent disease—not whether they relieve menopausal symptoms. In fact, most of the women in the WHI were 10 years older than women who use hormones to relieve menopausal symptoms, and most of the WHI study participants had no menopausal symptoms while they were enrolled in the study. So although the WHI clearly showed that hormones should not be used for disease prevention, they are still appropriate as a treatment for the relief of menopausal
symptoms.

Hormones do help
For many menopausal women, hormone therapy helps alleviate one of the most debilitating
symptoms of menopause: hot flashes. The American College of Obstetricians and Gynecologists (ACOG) hormone therapy task force found that menopausal hormone therapy, either in pill or patch form, can reduce hot flashes by up to 90 percent.
During a hot flash, the face and neck become flushed and blotches may appear on the chest, back and arms. Heavy sweating and
cold shivering can follow.
“People often don’t realize how debilitating hot flashes can be,” says Dr. Terry. “They not only disrupt a woman’s sleep, but also have a ripple effect on mood, coping ability, and relationships at home and at work.”
With the loss of estrogen at menopause, women also can experience vaginal dryness or vaginal
atrophy, which can lead to painful intercourse. Physicians often prescribe hormone therapy to
treat this problem.
“After menopause, vaginal lubrication is diminished, and tissues become dry and irritated,” says
Shaw. “Even low-dose therapies and topical estrogen creams can relieve the dryness and significant
discomfort that accompanies this condition.”
“Vaginal hormones, such as a slow-release ring, cream, or vaginal pill are necessary for a lot of
women,” says Dr. Terry. “The ring is particularly useful for women with breast cancer, because it
provides a low dose of estrogen that is released slowly.”
Hormone therapy also may protect postmenopausal women from osteoporosis, a potentially
disabling disease caused by loss of bone mass. According to the National Osteoporosis
Foundation, of the 10 million Americans believed to have osteoporosis, 80 percent are women. |
Osteoporosis is a major cause of bone
fractures in post-menopausal women.
“Estrogen therapies protect against
not just osteoporosis, but also osteopenia
(early-stage bone loss),” says Shaw. “We
get very concerned about osteoporosis,
because many active, healthy women
suffer fractures that impact their mobility
and quality of life. In fact, hip fractures
in women are associated with significant
morbidity and mortality. It’s important to
help prevent this.”
Proceed with caution
Current guidelines from the ACOG
and the North American Menopause
Society emphasize that hormone therapy
be prescribed at the lowest effective dose
and used for the shortest duration possible.
“We used to prescribe very high
doses of estrogen, telling patients they
would be taking it for the rest of their
life,” says Shaw. “Now we tell them
therapy is for a limited time and get
them on as low a dose as possible.
We’re using five years as a guideline,
although that is not supported by any
medical research. After five years of
menopausal hormone therapy, we evaluate
a woman’s symptoms and medical
history and make a mutual decision if
she will continue treatment.”
For some women, a type of antidepressant
known as a selective serotonin
re-uptake inhibitor (SSRI) may relieve
hot flashes in addition to depressive
symptoms of menopause.
“Antidepressants don’t work for everybody,
but they’re something to try and a
good option for women with breast cancer
who can’t take any kind of hormones
for five years after their diagnosis,” says
Dr. Terry.
Herbal hype
Herbal nutritional supplements and
over-the-counter remedies promise to
make menopause more comfortable and
tolerable, but these products and their
marketing claims are neither supported
by scientific studies nor regulated by the
U.S. Food and Drug Administration
(FDA). Some of the most recognized
herbal remedies for menopause include
soy and isoflavones, St. John’s wort, black
cohosh, evening primrose, dong quai and
ginseng.
“One of our biggest concerns is that
the herbal market is not regulated by the
federal government and, therefore, medical
providers do not have confidence
in the control, safety or effectiveness of
these products,” says Shaw.
“Potency can vary. Some have little
estrogen—and some have a level of
estrogen that puts people at high risk
for abnormal bleeding and blood clots.
There have been no large-scale studies
to support use of these products, and
we don’t know enough at this point to
recommend herbal supplements.”
Shaw cautions against products that
are labeled as “natural.”
“Someone has figured out when
women see the word ‘natural,’ they
feel the product is safe and better for
them, and even without risks,” she says.
“But it’s very important for women
to understand that estrogen-containing
products, whether prescribed by
your health care provider or purchased
over the counter, are made from the
same synthetic, animal or plant source.
Many of the products you can buy
over the counter contain plant extracts
in addition to chemically synthesized
hormones.
If you decide to take herbal
therapies or compounded hormonal
therapies, you should tell your doctor,
as these products have the potential
to cause drug interactions with other
medications you may be taking.”
A personal decision
If you are menopausal and considering
hormone or antidepressant therapy
to relieve your symptoms, talk to your
health care provider.
“Therapy is very individualized now,
and all women deserve in-depth education
on the risks and benefits of hormone
therapy to help them make an
informed decision,” says Shaw. “Also,
for women taking menopausal hormone
therapy, it’s very important that
they see their provider once a year
to discuss whether they are ready to
stop hormone therapy and see what
new research is available to help them
make that decision. All women also
should continue their annual breast
cancer screening, including a clinical
breast examination and periodic mammograms,
in addition to an annual
gynecological exam.” |
