To Hormone Replace or Not To Hormone
Replace
Thoughts on the WHI Study
Whole Woman, PC: February Newsletter
Since July, 2002, I have had hundreds of conversations with my patients,
colleagues and friends about what this information means. For
those of you who hate suspense, I'll let you know right now that there
will be no Answer given at the end of this column. In my view, the
idea that there ever was or will be one Answer to the question of
hormone replacement is part of the problem. Instead, I will share
with you my thoughts on what the important issues are, so that you can
reach your own conclusions like the intelligent and capable women that
you are.First of all, the facts: In July, 2002, the Women's
Health Initiative study (WHI for short) announced it was halting one
portion or "treatment arm" because of unacceptably high risk of breast
cancer, heart attack and stroke in the patients under study. These
patients had been taking the most widely used form of hormone
replacement, Prempro, for about 5 years. The patients who were
taking only Premarin (possibly because they had had hysterectomies)
displayed no such increased risk, and are still being studied.
There are several issues to consider here. First, the increased
health risks should be put into perspective. The increased breast
cancer risk amounts to an extra 8 cases per 10,000 women per year.
The increase in heart attack and stroke is somewhat less. These
figures sure sound less scary than the "25% increase" in breast cancer
quoted in some news reports. It's good to keep in mind that
statistics can be very misleading, even if true.
Second, the findings apply to Prempro, and cannot be extrapolated to
all HRT, as many media reports so irresponsibly implied. Prempro
is a combination of Premarin (a mix of estrogens obtained from pregnant
mares' urine) and Provera, a synthetic progestin which is sort of like,
but not the same as, your body's progesterone. All we can tell
from this study is that in this group of women (mostly over 60), on this
particular form of hormone replacement, at this "one size fits all"
standard dose, there is a definite small increase in breast cancer and
cardiovascular events.
Now that hopefully some perspective has been introduced, a rational
discussion should be possible.
You should know that there are many ways to replace hormones besides
Prempro. In my view the optimal way is with bioidentical (i.e.
exactly the same as your body makes) types. ALL the estrogen
patches (except Combipatch) are bioidentical, as are Estrace tablets and
Ogen tablets. The only commercially made bioidentical
progesterones are Prometrium, a pill form, and Crinone, a vaginal gel.
Other brands such as Menest, Aygestin, Activella and FemHRT contain some
or all synthetic hormones. Some claim to be "natural" because they
are obtained from plants. The truth is that all forms of
hormone replacement therapy besides Premarin are obtained from either
soybean or wild yam; the plant compounds are converted in the lab to
whatever hormone is desired (bioidentical or not). So the words
"natural" or "plant based" are not too helpful.
Outside of pharmaceutical companies, bioidentical estrogen and/or
progesterone can be obtained (with a prescription) in every type of
vehicle (tablet, capsule, lozenge, cream, gel) at compounding
pharmacies. These are pharmacies that custom-make medicines to a
physician's order. There are many of these pharmacies in the
Denver metro area, such as Pen-Col, Belmar, Cornell, and The Herbal
Remedy. A popular blend of estrogens offered by the compounding
pharmacies is Tri-Est, which some of you will have heard about. It
contains estradiol, the most potent of the body's three estrogens and
the one found in the patches, as well as estrone (found in Ogen) and
estriol, a weaker estrogen seen in the body mostly in pregnancy.
The estriol is included because of some interesting but very preliminary
data that indicate it might protect breast tissue from cancer.
Estriol is fairly popular in Europe for hormone replacement. I use
compounded hormone preparations quite often to meet particular patient
preferences or needs. Their downside is they are not always
covered by insurance, and cost $30 per hormone per month.
Are bioidentical hormones safe? We don't really know.
There is some good evidence that progesterone is more heart
protective than the synthetic, Provera. Maybe now that the WHI has
stirred everyone up, we'll get some badly needed studies on the
bioidentical preparations. Meanwhile, the most appealing reason to
go with them in my view is simple common sense. The body is
incredibly precise and elegant. Tiny alterations in molecules can
be catastrophic (such as the slightly altered hemoglobin which results
in sickle cell anemia). Hormones are some of the most potent
substances in the body and have effects on nearly every organ, including
the brain. If you are going to replace such a substance, it makes
sense to use that exact substance whenever possible, and not
something "pretty much like it."
Enough about the wide range of hormone replacement options.
There are plenty of you who have made up your minds never (or never
again) to take any hormones. Good news! You have plenty of
options too. Less good news! Even more than the
hormone-replaced group, you will need to pay close attention to taking
good care of yourself---body, mind, and spirit. Some women sail
through menopause, some are nearly incapacitated, but most will
experience discomfort somewhere in between. For all of you,
dealing with menopause symptoms starts with a good foundation.
Diet: lots of fresh whole foods (fruits, vegetables, whole
grains, fish, lean meats, nuts). Minimize refined carbohydrates
(sweets and sweet drinks, most cold breakfast cereal, anything made with
white flour) and hydrogenated fats (anything deep fried, most
margarines, most commercially made baked goods). Include 1-3
servings of soy protein daily. Caffeine and alcohol are notorious
for bringing on hot flashes, aggravating mood swings and interfering
with sleep. You decide. Exercise: it's more important
to be regular than heroic. 30 minutes daily of brisk walking,
biking, or "sweatin' to the oldies" beats a once weekly mega-workout at
the gym. Herbs and supplements: The best known herb
for fighting hot flashes is black cohosh. Dose is 40mg 2-3 times
per day. The max. effect will be seen after 8 weeks, so this is
not a quick fix. Other helpful herbs include Vitex (chastetree),
red clover, and sometimes dong quai. It's OK to try a "women's
herbal blend" which contains several of these. When possible buy
an herbal tincture (concentrated extract) rather than capsules; potency
is much better. Helpful supplements include omega-3 fats (fish or
flax oil), 3000mg per day; a calcium preparation (not carbonate) that
includes magnesium also, about 1000 and 500mg per day each, and a good
quality multivitamin such as Thorne or Rainbow Light.
Mind/Spirit: menopause is when many women discover journaling,
women's groups, regular meditation, massage, yoga and other forms of
managing stress and processing emotions...out of necessity! The
emotional changes at this time are similar to adolescence (remember THAT
roller coaster?). Luckily we don't have parents who can take away
the car keys, so we have more options.
To sum it all up: go with what makes the most sense to you.
We're all going to get health problems eventually. The role that
hormones play is probably much less important than our overall lifestyle
and emotional state. The goal is to feel good and be
happy. If that means staying on hormones by whatever route
feels best, fine! If it means choosing not to take a pill every
day that scares you, that's OK too! And if you decide later on
that you want to choose differently, you're allowed to change your mind.
