Balancing Hormone Function
in Women
By

Hormone
function is central to health and well being
in both men as well as women. A problem encountered
with any one endocrine gland can lead to a number
of clinical conditions. Often, several are affected,
especially in women whose endocrine system fluctuates
frequently. Therefore, disturbances are frequently
seen and can be difficult to sort through. A
multi-systems approach to evaluation and treatment
of endocrine system imbalances is a focus on
naturopathic medicine.
One of the most commonly encountered conditions
seen by physicians are problems associated with
the thyroid gland. The lack of adequate amounts
of thyroid hormone levels in the body can cause
weight gain, fatigue, lack of desire and motivation,
depression, brain fog, night sweats, hot flashes,
vaginal dryness, mood swings, insomnia, lack
of temperature regulation, cold hands and feet,
and food cravings. Many of these symptoms may
sound familiar, as most everyone will experience
them at some point in their lives. However,
if they persist, an evaluation of thyroid function
is indicated.
While the thyroid glands function can be measured
by blood or salivary testing, it does not act
as an independent entity as it is interconnected
with all of the other endocrine glands. Because
of this, problems with thyroid function may
be due to problems in other areas.
The primary regulator of hormone function is
the master gland, which is the pituitary. Located
at the base of the hypothalamus it sends signals
to various other glands in the body. For example,
it sends signal in form of TSH (Thyroid Stimulating
Hormone) to the Thyroid gland located in the
neck to produce the Thyroid Hormone, T4 (Thyroxine).
Likewise it sends signal in the form of ACTH
(Adrenocorticotropic Hormone) to the Adrenal
glands located on top of your kidneys to produce
cortisol and adrenaline, and also sends signals
in the form of FSH (Follicle Stimulating Hormone)
and LH (Luteinizing Hormone) to the ovaries
and testis to produce Estrogen and Testosterone.
Similarly, the pituitary gland sends signals
to various other glands in the body to produce
other hormones while attempting to maintain
a balance.
The thyroid gland is responsible for maintaining
the body’s metabolism. Thus, if the thyroid
gland is functioning optimally, then the mitochondria
in the cells are producing adequate ATP or energy.
The thyroid gland produces Thyroxine (T4) primarily
which is converted to Triiodothyronine (T3),
the active thyroid hormone. Thus a conversion
of T4 to T3 is important for the body to utilize
it. This step of T4 to T3 conversion requires
an enzyme and certain nutrients, specifically
iodine. If thyroid hormone production is lowered,
it means the metabolic rate is reduced and the
patient will experience lower energy or fatigue
and will gain weight. This is termed hypothyroidism.
Other signs and symptoms of hypothyroid include
feeling cold, having cold hands and feet, loss
of hair, dry skin, thinning of outer third of
your eyebrows, brain fogginess, and depression.
While hypothyroidism is much more commonly seen,
some people can develop a condition with an
increased amount of thyroid hormone production,
termed hyperthyroidism.
The treatment for a hypothyroid patient is to
replace the deficient thyroid hormones while
attempting to support the thyroid gland nutritionally
so that it can produce adequate levels. The
most common conventional medicine approach is
to use a synthetically derived T4 hormone called
Synthroid. In order for it to work, the body
has to convert it to T3 for it to be utilized
as occurs with the natural hormone produced
by the thyroid. Some physicians prescribe a
combination of T4 and T3 so the body does not
have to work so hard in making the conversion
and readily use the active hormone T3.
Naturally derived thyroid medications such as
Armour Thyroid, Nature thyroid, or desiccated
thyroids that are utilized by compounding pharmacies,
are porcine derived thyroid medication which
has both T4 and T3. These have been found to
be much more biologically active than the synthetics
as they are more closely allied to what the
human body produces.
In order to check thyroid function we perform
a thyroid function panel which includes TSH,
Total T4, Free T4, and a T3 Uptake. Typically,
most medical doctors will test the TSH only
to assess function. The problem with just assessing
TSH levels is that they are only assessing the
pituitary function and not able to evaluate
its effect on the thyroid gland, its target
gland. TSH is a pituitary hormone produced in
response to circulating T4 and T3 levels and
will be elevated when there is a low level of
T4 and T3. This indicates a low production of
thyroid hormone thus resulting in an increase
in TSH in order to produce more hormones. However,
while it is telling the thyroid gland to produce
more thyroid hormone, the thyroid gland may
not able to produce adequate levels for a number
of reasons. Often the levels of T4 and T3 are
within the “reference” range but
sub-clinically low. What this means is that
the thyroid gland is not able to respond adequately
to the pituitary output, or the pituitary output
isn’t adequate enough for the thyroid
to respond. The clinician must then sort through
the possible scenarios and figure out where
the problem lies in order to correct it.
In order to determine the underlying problem
we will also test for the thyroid antibodies,
anti-thyroperoxidase (Anti-TPO) and anti-thyroglobulin
(Anti-TG). Produced as a result of an autoimmune
condition these antibodies attack the thyroid
gland decreasing its response to TSH which suppresses
production of thyroid hormones. It is the body’s
own immune system attacking the thyroid gland
and is known as Hashimoto's Thyroiditis. For
whatever reasons, the incidence of Hashimoto’s
disease has increased, and is more often seen
in women.
Adrenal and ovarian function follows a similar
feedback loop with the pituitary gland much
like the thyroid. Our adrenal glands produce
hormones in response to stress. Cortisol and
DHEA-S are the primary hormones used in assessing
adrenal gland function. Cortisol levels are
increased in times of chronic stress and can
lead to weight gain around the abdomen. It could
be physical, mental or emotional stress that
is experienced over long periods that eventually
exhausts the adrenal production of cortisol
leading to Adrenal Fatigue. Cortisol levels
vary during the day, with their being the highest
in the morning and lowest at night. If the opposite
occurs, meaning the patient has low cortisol
levels in the morning then they can have difficult
time getting up from bed in the morning and
the higher levels in the night can cause difficulty
falling asleep. Cortisol levels are best evaluated
with a salivary Adrenal Stress Index kit, as
they are a better indicator of biologically
active hormone levels than blood tests. It is
performed by collecting saliva samples at 8am,
noon, 4 pm and 11pm which helps the clinician
to follow the body’s normal diurnal variation.
Ovarian hormone production is a very important
topic for all women, but especially those who
are peri-menopausal or going through menopause.
Women who are experiencing problems with ovarian
hormone production and regulation complain of
hot flashes, night sweats, brain fogginess,
vaginal dryness, no desire for sex, sleep problems,
and mood swings. Many women report that they
don't feel like themselves any more. The reason
that this feeling occurs is not just in their
heads but it is because their hormone levels
have dropped significantly.
The ovaries produce estrogens, so when they
stop producing, a feedback signal goes to pituitary
that in turn increases the FSH (follicle stimulating
hormone). This occurrence indicates the women
is in menopause. There are three kinds of Estrogens
E1 (Estrone), E2 (Estradiol) and E3 (Estriol).
E1 is the bad estrogen that causes symptoms
of breast tenderness, E2 is the one that is
mostly utilized by the body and needs to be
replaced while E3 is the weaker one of them
which is sometimes useful when used vaginally
in a cream form for vaginal dryness. Progesterone
(P4) is the other important female hormone that
needs to be replaced when using hormone replacement
therapy as it helps to balance estrogen levels.
Women also need testosterone but in much smaller
amounts than men. Typically blood testing for
the various hormone levels are performed but
salivary levels often provide a more accurate
assessment of what is going on at the cellular
level and seem to have a better clinical correlation
with HRT.
Frequently women want to know what is the difference
between Bioidentical Hormone Replacement and
Hormone Replacement? The answer is that synthetic
hormones, the most commonly used one being Premarin,
is made from the pregnant mare's urine. A mare
makes 50 different kinds of estrogen which are
good for horses but is not as useful for humans,
so why give the body estrogens that it does
not need or make? Bio-identical hormones are
made from soy. Soy has a basic chemical structure
that can easily be made into the structure of
the hormone that the body naturally makes, thus
called termed bio-identical.
Personally, having a conservative approach in
medicine, when a patient comes to me with these
symptoms, I first take a complete history, order
relevant lab work, and then based on the results
form an individualized treatment plan. I approach
the case and plan the treatment based on the
degree of dysfunction and have a leveled approach.
The first level is helping the gland with herbal
support so that it begins producing hormones
on its own, the second level is using glandulars
or protomorphogens and the third and last level
is using hormone replacement therapy when the
gland has lost the ability to produce hormones
on its own.
The treatment is individualized based on patient
symptoms, lab results and age. It is extremely
important to address other factors like patient's
diet, exercise, and nutrition while balancing
the hormones. Also, hormone balancing done with
Estradiol and Testosterone is not only to help
a women get rid of the symptoms but also prevent
her from osteoporosis and heart disease. How
many people have you known who have gone to
their doctor and complained of feeling the way
they are and come back with a script for a mood
disorder medication? Symptoms of hormone imbalance
are not a mental disorder but a physiological
one that can be corrected with proper evaluation
and therapy.
