Thyroid health
Hypothyroidism in menopause — a whole-body perspective
by Marcelle Pick, OB/GYN NP
I talk to women daily about hypothyroidism in my practice, and one thing I hear
over and over from those who have been diagnosed is, “I thought I was healthy. How
did this happen?” Many women with hypothyroidism are struggling with
weight gain, fatigue, poor concentration, hair loss, even depression — and
they want answers about how to feel better.
About one in five of the midlife women we see at our practice have
abnormal TSH levels. So it isn’t just a problem for women who don’t pay
attention to their health — even Oprah Winfrey, who’s extremely health conscious, has talked about
her hypothyroid condition. The fact is, women are often diagnosed
with hypothyroidism during perimenopause and menopause,
but few conventional practitioners talk about this connection. And even fewer offer
solutions beyond synthetic thyroid hormone replacement medications like levothyroxine
(Synthroid, Levoxyl, Levothroid, Unithroid) to bring TSH levels down.
I know women want to support their thyroid health. One way to start is by realizing
that hypothyroidism is rarely an isolated condition. There could be several factors
leading to your thyroid disturbance, especially during the menopause transition,
and these factors vary from woman to woman.
Let’s look at the other pieces to thyroid imbalance — because there is so much more
to the story than elevated TSH. When these surrounding issues are resolved, it’s
amazing how much better you can feel! So whatever your lab results may be, let’s
take a look at what might be leading to your hypothyroidism and how you can feel
better naturally.
A natural desire for balance: how the thyroid steadies us
Our bodies continually strive for a dynamic balance that shifts according to positive
and negative feedback messages from the brain and cells of the body. No matter what
the disruption, the human body has amazing capabilities in terms of reverting to
this dynamic balance. Centrally located between the brain and rest of the body,
the thyroid is like a “transfer station” for that balance.
Typical thyroid hormone ranges
It’s a good idea to have your thyroid hormones checked once a year. Your practitioner
should also check levels after two months if you’re starting a new thyroid medication
or dose. Here are the typical ranges:
- T4: 4.8–13.2 mcg/dL
- Free T4: 0.9–2 ng/dL
- T3: 80–200 ng/dL
- TSH: 0.4–4.0 mIU/L (if you have no hypothyroid or hyperthyroid symptoms) 0.3–3.0
mIU/L (if you’re being treated)
Keep in mind that “normal” ranges vary by laboratory and that anyone with a TSH
>2.0 mIU/L and no other “abnormal” levels should be followed closely to watch for
symptoms of hypothyroidism. I strive to keep TSH levels below 2.0 mIU/L in my patients,
even though the normal range goes up to 4.0 mIU/L.
Reference
The thyroid carries amazing responsibilities. Its hormones affect how you metabolize
food, store and use energy, think, talk, sleep and more! So it makes sense that
when the thyroid isn’t functioning properly, life can seem entirely off-kilter.
The hormones of the thyroid, thyroxine (T4) and triiodothyronine (T3), influence
the metabolism of every cell in our bodies. Because T3 is the form our cells recognize
best, it is more readily used and considered much “stronger” than T4. The more slow-acting
T4 can be converted into T3 in the liver, kidneys and elsewhere.
When T3 and T4 are low in the bloodstream, the hypothalamus — the “command center”
for hormones in the brain — sends TRH (thyrotropin-releasing hormone) to the pituitary
gland. A sort of “halfway house” between the brain and the endocrine system, the
pituitary gland interprets the message to secrete more TSH (thyroid-stimulating
hormone), which in turn prompts your thyroid gland to take up iodine and the amino
acid tyrosine to produce more T3 and T4.
Nature has created an elegant system of set points, feedback loops, and checks and
balances to support the thyroid’s dynamic equilibrium. So as long as things haven’t
gotten too far out of whack, it will always move toward its default “normal” state
if you support it. And support becomes increasingly important as we age, as many
women who are approaching menopause come to realize.
Hypothyroidism and menopause — how hormonal imbalance affects the thyroid
Most women agree that menopause is accompanied by profound changes on both emotional
and physical levels. This transition and the years leading up to it, known as perimenopause,
can cause the body to temporarily shift its balance while hormones recalibrate and
readjust to a new set of demands. With childbearing over, the body intelligently
conserves energy and slows production of reproductive hormones. In many cases, progesterone
is the first to decline, which temporarily leaves estrogen as the dominant hormone.
Some researchers and practitioners feel that an imbalance between estrogen and progesterone
(often called “estrogen dominance”) is a key factor in decreased thyroid function.
The combination of normal estrogen levels with decreased progesterone may block
the action of the thyroid hormone and lead to
symptoms of hypothyroidism, even as thyroid hormone levels appear normal
on lab results.
Hormonal imbalance contributes to perimenopausal and menopausal thyroid problems,
but I’ve found that there are additional factors to consider as well. The bodies’
systems are intimately connected, and a disease or disorder may not always begin
with the tissue or organ exhibiting the problem. And a disorder in the thyroid may
very well originate somewhere else in the body. Let’s begin with how the adrenal
glands influence thyroid function.

How your adrenals can affect your thyroid function
If patients come to see me with symptoms of hypothyroidism, one thing I do after
thyroid testing is evaluate their adrenal
function. Many women are surprised to learn there’s a connection between the two
(that is, if they’ve even heard of the adrenals!) But I’ve found overstressed adrenal
glands to be one of the most common contributors to hypothyroidism in my patients.
If you take a look at the diagram above, you can see that stress of any kind — mental,
emotional, or physical — stimulates the hypothalamic-pituitary-adrenal (HPA) axis,
the dynamic feedback system between the brain and the adrenal glands. Overstimulation
of this axis has huge implications throughout the body.
The short-term result of a stimulated HPA axis is higher cortisol production from
the adrenals. High cortisol (hypercortisolism) in the bloodstream can directly inhibit
production of TSH (thyroid-stimulating hormone) as well as conversion of T4 to T3.
But cortisol can’t remain high forever. Eventually, the adrenal glands reach exhaustion
and too little cortisol is produced (known as hypocortisolism), which comes with
another set of problems. For more on this topic, see our article on the
adrenal spectrum.
Either way, with lower levels of T3 in the blood, your cells can’t produce a healthy
biological response. This is when women begin to see
hypothyroidism symptoms like fatigue, cold intolerance, weight gain, memory
loss, poor concentration, depression, infertility, hair loss and more.
The prescription drug levothyroxine acts by replacing the body’s T4 with a synthetic
form. Though some women feel better on some form of levothyroxine, many do not.
As you can see from the diagram, when overstressed adrenals are at the root of your
thyroid trouble, feeding the body more T4 is a stop-gap solution that eventually
teaches the thyroid to stop producing its own T4. If you’re not already on synthetic
T4, it may be worthwhile finding out why thyroid function declined in the first
place — an important step toward correcting it.
The adrenal glands are one piece to the thyroid equation, but for other patients,
there may be something entirely different causing a sluggish thyroid. My experience
has shown me that looking deeper into the origins of a thyroid disorder can be much
more helpful in bringing TSH down, while at the same time creating whole-body wellness.
Other factors in the hypothyroidism equation
On top of the physical and emotional stress women feel at menopause, there are several
very real biological stresses on the thyroid to consider.
Low iodine levels. Iodine is the central ingredient in thyroid hormones T3 and T4.
Trying to produce T3 and T4 without iodine is like trying to make an omelet without
the eggs! We need about one milligram of iodine a week to form the required amount
of thyroxine.
But iodine is not all that widely distributed in nature. Despite iodine being added
to our commercial table salt, American iodine status was recently deemed “marginal”
by the World Health Organization. Given that many of the world’s crop-growing soils lack
iodine, fewer people eat foods naturally rich in iodine, and more and more avoid iodized
table salt, iodine deficiency
is on the rise.
Exposure to environmental toxins — including halides, heavy metals, pesticides,
and antibiotics in our air, food, and water — can also interfere with our thyroid
function. We all know it’s best to limit our toxic exposure wherever possible, but
increasing iodine intake and implementing a regular detox program to support the
body’s natural detoxification pathways
can also make a difference.
Food allergies and sensitivities — including to gluten — can place tremendous stress
on thyroid function. Many of my patients with hypothyroidism see positive results
when they eliminate gluten from their diets. You, too, may want to give an elimination
diet a try. This is a connection I’ve noticed for several years, and research around
the world is bearing this out.
Food sensitivities may also promote autoimmune reactions in which the body’s immune
system attacks the thyroid as though it were a foreign invader. More research is
called for in this area, but it’s now clear that the food we eat “talks” to our
genes. And when we have food intolerances occurring in the gut, the resulting chemical signals
influence our DNA — including the DNA in our immune cells. Unfortunately, the messages
carried by food stressors turn off the default “healthy” pathways and turn on those
that lead to disease.
A long list of prescription medications can also impair thyroid function. Drugs
like lithium, amiodarone, somatostatin, inhalers, and others have the potential
to disrupt thyroid hormone balance at any level — from synthesis, secretion and
transport, to how thyroid hormones act in our organs to regulate metabolism — with
an the unintended outcome of hypothyroidism or
hyperthyroidism. I acknowledge that prescription medications save lives,
but we have to be mindful that their benefits often come at the expense of other
systems in the body. Sadly, the targeted strength provided by many drugs can be
overwhelming — in some cases destructive — to the thyroid.
Finally, insufficient nutrition may also affect thyroid function — but it’s a problem
that’s easily addressed! Selenium, for example, is needed for the conversion of
T4 to T3, so if you’re selenium deficient, increasing this nutrient in your diet
may make a difference in how you feel. And as mentioned above, iodine is essential
for making thyroid hormones. Vitamin A, EPA and DHA, and zinc all act to improve
T3 binding in your cells. By working with your body’s natural pathways, vitamins,
minerals, omega-3 fatty acids,
and extra antioxidants can offer great results without the side effects. The bottom
line is that when we give our bodies the gentle support they recognize, we often
see positive results that last.
Natural hypothyroid relief — from Women to Women
Menopause is a time of profound transition — one that can take its toll on the mind
and body, particularly the thyroid. Hypothyroidism may be the manifestation of many
different imbalances, and the best way to restore healthy thyroid function in the
present is by looking into the problem’s past to address the root causes.
After years of clinical experience, I’ve seen women greatly improve by implementing
elements of the natural approach I use to give women with hypothyroidism a better
future.
Nutrient-rich foods to replenish thyroid health
- Iodine (I): seaweed (e.g., nori), clams, shrimp, haddock, oysters, salmon, sardines,
pineapple, eggs.
- Selenium (Se): smoked herring, smelt, wheat germ, Brazil nuts (just one nut provides
~139 mcg), apple cider vinegar, scallops, barley, lobster.
- Zinc (Zn): fresh oysters, ginger root, pecans, dry split peas, Brazil nuts, egg
yolk, whole wheat, rye, oats, peanuts.
- Vitamin E: wheat germ oil, olive oil, sunflower seeds, almonds, peanuts.
- Vitamin A: dark green leafy veggies, liver, winter squash, cantaloupe, stone fruits,
papaya, and cod liver oil.
- B vitamin complex: brewer’s yeast, wild rice, brown rice, whole wheat, beans, peanuts.
- Vitamin C: Red chili, guava, parsley, dark green leafy veggies, strawberries, papaya,
citrus fruits.

- Support your adrenals. If this is the
only thing you do, I promise it will benefit your health on many levels. Not only
will supporting your adrenals lighten the burden of your thyroid, it will also help
restore your energy levels and overall well-being.
- Introduce a quality multivitamin–mineral complex. I encourage all my perimenopausal
and menopausal patients to take a pharmaceutical-grade supplement like our Essential
Nutrients. Ensuring a rich foundation of nutrients for the daily production and
activity of thyroid hormones may be all you need to get yourself back on track,
or to prevent hypothyroidism.
- Consider supplementing with selenium and iodine. Ask your practitioner to test your
iodine levels, and talk about boosting your iodine and selenium levels in addition
to your multivitamin. You can do this through the foods you eat (see the box) or
with supplements, but if you do use selenium or iodine supplements, please work
with a professional healthcare provider to monitor your levels appropriately. And
when it comes to selenium supplements, I do not recommend taking more than 200 mcg/day.
- Find ways to diminish stress and speak your truth. By the time we reach perimenopause,
many of us find we’ve given so much to the world around us there is little reserve
for ourselves. This is the time to speak up, to share your opinions, to explore
the things that make your life meaningful. Don’t feel guilty about asking for —
and receiving — more support. Though easier said than done for many women, this
may be the perfect time in life to learn to say “no.” You deserve a break — and
so do the cells in your body!
Remember to have your practitioner examine your thyroid and thyroid hormone levels
once a year, to stay on top of any changes.
If you make these changes and your thyroid hormone levels still aren’t right (or
you’re still experiencing symptoms despite “normal” TSH), then it is worth considering
using thyroid medications. For some women, levothyroxine is all they need to feel
much, much better. But others don’t quite get the relief they were looking for with
synthetic T4. Should you find you need additional support, ask your practitioner
about a prescription for natural
thyroid hormones, such as Armour Thyroid, WestThroid, and Nature-Throid.
Another alternative is compounded individualized levels of T3 and T4. The combination
of both T4 and T3 often makes a dramatic difference for women suffering from symptoms
of severe hypothyroidism. Keep in mind that these natural and compounded forms are
somewhat controversial, so some practitioners might be unwilling to consider it
an option, and you may need to seek a second (or a third) opinion.
Your thyroid, your voice
In Eastern medical paradigms, the thyroid is associated with “sacred voice.” As
a component of the fifth chakra, thyroid issues are linked with difficulty speaking
our truth, following our dreams, or fully expressing ourselves. Anatomically, the
thyroid sits right over the voice box, and one of the symptoms of thyroid dysfunction
is a gravelly or “muted” voice. When the thyroid is underactive, it doesn’t hurt
to step back and evaluate how well you’re expressing your individual needs, wants,
and opinions to those around you.
Remember that your voice doesn’t serve to merely communicate — it is connected to
your whole being. Likewise, your thyroid doesn’t simply produce thyroid hormone.
It is connected to every cell in your body and subject to physical as well as psychological
influence. My advice is to look at the whole picture when it comes to your thyroid,
and you will find the dynamic balance your body is naturally seeking.
