Hormone Testing in Perimenopause and Post-Menopause

Is Hormone Testing in Perimenopause and during Post-menopause helpful?
Every day in practice patients ask me if we can test their hormones.
As a naturopathic doctor who supports women during mid-life, my answer is always
“Yes, of course we can.” But I follow this response with a discussion that clinical context
is important to consider when deciding what information we are looking for, which
hormones should be tested, when to test, and whether to test in blood, urine and/or
saliva.
I spend a lot of my clinical days supporting women through the perimenopause and
menopause transition. I have been fortunate to have had access to consistent
continuing education in perimenopause and menopause over the past 25 years of
practice. During all these years, MHT (menopause hormone therapy) was not
commonly prescribed for women. Women needing support often turned to naturopathic
doctors for assessment and an individualized plan using herbs and nutritional supports.
With health authorities having lifted the black box warning on applicable estrogen
products, many (not all) women are seeking out hormone therapy options for both
symptomatic relief and preventative support for bone density. (1)
Although I have additional training in therapeutic prescribing, prescribing
pharmaceuticals, including hormones, is not currently in the scope of practice for
Naturopathic Doctors in Saskatchewan. However, my patients experiencing this
hormone transition find having an ND as part of their healthcare team beneficial for
many reasons. Testing options is one of them.
Healthcare practitioners agree that symptoms in the perimenopausal and menopausal
transition are going to be most helpful in guiding treatment. However, hormone testing
may provide useful information to help optimize a treatment plan and facilitate patient
understanding and engagement.
Hormone testing options may include:
1. Serum blood testing of hormones can provide a snapshot of total hormone
levels, bound and unbound. Blood levels can be measured at certain times of an
individual’s menstrual cycle for general information during that cycle or during
flares in symptoms to understand how hormone changes happening at that time
relate to the symptoms the patient is experiencing. Post-menopausally, blood
hormone levels are more stable. Serum hormone testing is standard of care to
monitor oral MHT, pellets or patches.
2. Saliva testing is an option that is an easy collection without requiring a blood
draw. It provides an option to assess free, bioavailable hormone levels (rather
than total, bound and un-bound hormone) reflecting tissue-level availability
because only free hormones cross into saliva. It is also a convenient option to test
hormones at more than one time of the day. This is particularly helpful for
assessing cortisol hormone levels.
Saliva hormone testing has limitations with oral MHT intake as oral MHT may
contaminate the salivary reservoir. It’s a consideration for those on topical
creams or gels however it’s generally not recommended by medical authorities to
manage patient on MHT.
3. Urine testing offers a broader look at how hormones are being cleared and
measures their breakdown metabolites which are biologically active as well and
can also be contributing to symptoms. This sample can also be collected at home
and mailed off to a private laboratory.
Other testing is also an essential part of a thorough work up for mid-life health.
This includes:
a. A more comprehensive assessment of health parameters that can affect
ovarian hormone levels or contribute to symptoms in mid-life. Examples
include thyroid hormones, adrenal hormone, dhea, iron and ferritin, and
vitamins B12 and D.
b. Testing for contributors of weight gain which is a common during the
perimenopause transition. Examples include fasting insulin, cortisol and
comprehensive thyroid testing.
c. Testing for markers of cardiovascular health such as lipids, homocysteine
and crp to inform on an individualized preventative plan.
Here is some more explanation of when I find testing hormones to be
helpful:
During Perimenopause
During the reproductive years, estrogen and progesterone follow patterns that are linked
to the menstrual cycle.
As ovarian function begins to change, that predictability often starts to disappear.
Ovulation may occur regularly one month and not the next. Progesterone can therefore
vary considerably depending on whether ovulation occurred. Estrogen can also rise and
fall throughout the transition.
At the same time, the brain is sending stronger signals to the ovaries through hormones
such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Cycle length,
the amount of blood loss and hormonal symptoms can vary and give information about
the changing hormone levels.
Hormone testing when concerning symptoms are present or testing hormones more
than once a month can be very helpful in directing treatment. This can be particularly
helpful during perimenopause when there is no bleed due to an ablation or an IUD.
Once menopause has occurred
Once a woman is postmenopausal (over 12 months without a bleed), we know that both
estrogen and progesterone levels are going to be more stable with a substantially lower
baseline that the premenopausal years. The priority in care shifts to managing
symptoms that haven’t resolved with the transition through menopause while focusing
on preventative health.
Symptoms assessed include hot flashes, sleep, night sweats, mood, vaginal or urinary
discomfort, and libido. When MHT is being considered or adjusted, symptom response
is an critical part of the decision.
The North American Menopause Society emphasizes that hormone therapy should be
individualized according to the woman's symptoms, health profile, treatment goals,
dose, duration, regimen, and route of administration, with periodic reassessment of
benefits and risks.(2) The current clinical guidance does not recommend titrating
systemic menopausal hormone therapy to a particular serum hormone level.(2)
A laboratory value is not the guiding information for a prescription of MRT which is a
small amount of hormone compared to physiological levels in menstruating years. It is
important that the progesterone dose is proportionate to the estrogen dose to oppose
the proliferative effects of estrogen on the uterine lining.
And let’s not forget about testosterone. Testosterone plays an important role in energy,
cognition, sexual health and body composition. Testing dhea (the adrenal hormone
precursor) and testosterone can help provide more direction for actionable supports.
Testing different androgens (male hormones) can give helpful insight into symptoms
such as hair loss and acne during a woman’s hormone transition.
The most important measurement may be how you feel, however for optimal health now and as you get older, hormone testing can be helpful.
If you would like to understand what your body is telling you and feel confident that you
are supporting your hormone balance optimally during perimenopause and through the
menopause transition, you may find a relationship with a Naturopathic Doctor and some
testing to be a helpful support.
