Which Hormones Need
Testing?
The major sex
hormones to assess are estradiol, progesterone and
testosterone. The main adrenal hormones are DHEA and
cortisol. These five hormones will provide crucial
information about deficiencies, excesses and daily patterns,
which then result in a specifically tailored treatment
approach and one far more beneficial than the old “shotgun"
approach.
Below is a brief description of
each of these five hormones:
Estrogen:
there are
three forms made by the body: estrone, estradiol and estriol.
The form used in past hormone replacement therapies is
estradiol, often in the form of concentrated pregnant mare’s
urine (premarin).
It is a proliferative (causes growth) hormone that grows the
lining of the uterus.
It is also a known cancer-causing hormone: breast and
endometrial (uterine) in women and prostate gland in men. It
will treat menopausal symptoms like hot flashes, insomnia and
memory-loss. With the bio-identical formulas estriol is matched
with estradiol (biest) to provide protective effects and
additional estrogenic benefits. The other major protector in
keeping estradiol from running amok is
progesterone.
Progesterone
is called
the anti-estrogen because it balances estradiol’s proliferative
effects. It is considered preventive for breast and prostate
cancers as well as osteoporosis. In addition too little
progesterone promotes depression, irritability, increased
inflammation, irregular menses, breast tenderness, urinary
frequency and prostate gland enlargement
(BPH).
Testosterone
is an
anabolic hormone (builds tissue) that is essential for men and
women. The proper level of testosterone is necessary for bone
health, muscle strength, stamina, sex drive and performance,
heart function and mental focus.
DHEA
is an
important adrenal gland hormone, which is essential for
energy production and blood sugar balance. DHEA is a
precursor to other hormones, mainly
testosterone.
Cortisol
is your
waking day hormone (highest in the morning and lowest at
night). It is necessary for energy production, blood sugar
metabolism, anti-inflammatory effects and stress
response.
Some of the common
imbalances identified through testing include estrogen
dominance, estrogen deficiency, progesterone deficiency,
androgen (testosterone and DHEA) excess or deficiencies,
adrenal dysfunction and adrenal fatigue.
ESTROGEN AND
PROGESTERONE:
Estradiol and
progesterone are 2 hormones that are often tested
together.
When you test these 2 hormones together we also provide you
with a Pg/E2 ratio. This ratio allows you to determine if the
patient (male or female) has “Estrogen Dominance". Estrogen
dominance is a risk factor for breast cancer and osteoporosis
in females and prostate gland enlargement and cancer in males.
The term “Estrogen
Dominance" is less related to the amount of circulating
estrogen and more related to the ratio of estrogen to
progesterone in the body. Menopause and PMS are not the
result of estrogen deficiency; although, estrogen levels do
decline during the latter phases of a woman’s reproductive
cycle.
More relevant is that the estrogen levels drop by approximately
40% at menopause or during periods of stress while progesterone
levels plummet by approximately 90% from premenopausal
levels.
It is the relative loss of progesterone that causes the
majority of symptoms termed estrogen dominance. The
disproportionate loss of progesterone begins in the latter
stages of a woman's reproductive cycle, when the luteal phase
of the menstrual cycle begins to malfunction.
The malfunction is initiated when the corpus luteum, the
primary source of progesterone, begins to lose its functional
capacity. By about age 35, many of these follicles fail to
develop creating a relative progesterone deficiency. As a
result, ovulation does not always occur and progesterone levels
steadily decline.
It is during this period that a relative progesterone
deficiency, or what has become known as Estrogen Dominance,
develops.
Typical
Symptoms of Estrogen Dominance
Include:
Irritability/Mood
Swings
Depression
Irregular Periods
Heavy Menstrual
Bleeding
Vaginal Dryness
Water Retention
Sleep Disturbance
Hot Flashes
Headaches
Fatigue
Short-term Memory
Loss
Weight Gain
The
Progesterone/Estradiol (Pg/E2) reference ranges are optimal
ranges determined by Dr. John R. Lee MD. While they are not
physiological ranges, they are optimal values for the
protection of the breasts, heart and bones in women, and the
prostate in men.
Salivary values within these ranges have been shown by Dr. Lee
to decrease both breast and prostate cellular proliferation,
thereby providing protection to these vital tissues.
TESTOSTERONE:
Testosterone is
often tested because the patient talks of low libido.
Declining testosterone levels are the number one cause of
low libido in males, and plays a contributing factor in
females.
Declining
testosterone levels are commonly seen in men beginning in
the fourth decade of life. Suboptimal or low testosterone
levels in males are often associated with symptoms of aging
and are referred to as “Andropause" or male menopause.
Testosterone is an
important anabolic hormone in men. It increases energy,
prevents fatigue, helps maintain normal sex drive, increases
strength of all structural tissues such as
skin/bone/muscles; including the heart and prevents
depression and mental fatigue.
Testosterone deficiency is often associated with symptoms such
as night sweats, insulin resistance, erectile dysfunction, low
sex drive, decreased mental and physical ability, lower
ambition, loss of muscle mass and weight gain in the waist. The
primary cause of this increase in girth is visceral fat, not
excessive subcutaneous fat (fat under the skin).
The visceral fat
cells are the most insulin resistant cells in the human
body. As a person ages hormone levels change in favor of
insulin resistance. The insulin levels rise while
progesterone, growth hormone and testosterone decline.
The visceral fat cell begins to collect more fat in the form of
triglycerides. A vicious cycle is initiated, which if not
interrupted with natural hormone balancing will lead to
abdominal obesity, diabetes and high cholesterol levels.
This phenomenon is known as “Metabolic Syndrome". In males,
metabolic syndrome results in lower testosterone levels,
however, in females metabolic syndrome results in high
testosterone levels and a phenomenon known as Polycystic
Ovarian Syndrome (see below).
Stress management,
exercise, proper nutrition, dietary supplements, and
androgen replacement therapy have all been shown to raise
androgen levels in men and help counter male metabolic
syndrome symptoms.
The “trick" is to know how much testosterone is required for
each individual male. This is where knowing the salivary
testosterone levels come into play. Initial salivary testing
and following salivary monitoring are crucial for determining
the most optimal prescription.
Metabolic Syndrome
and Polycystic Ovarian Syndrome (PCOS) in females results in
the same visceral fat pattern, insulin resistance and
triglyceride formation as in males, however, the female
patients with PCOS and metabolic syndrome had high levels of
testosterone and often DHEA.
This results in a typical symptom pattern seen in women with
metabolic syndrome – acne, increased facial and body hair, hair
loss on the head, trunkle obesity and infertility. Salivary
testosterone and DHEA levels are diagnostic for this syndrome
and follow up testing is key for monitoring treatment.
It is important to note that women do not need to have their
ovaries to have metabolic syndrome. The adrenal glands in women
who have a predisposition to metabolic syndrome can produce
above normal levels of testosterone and
DHEA.
DHEA AND
CORTISOL:
DHEA is often
thought of as an adrenal hormone and in fact it is, however,
DHEA is also made in the ovaries. When we measure DHEA we
are eliciting information about both the adrenal glands and
the ovaries.
This is particularly important when DHEA levels are high. High
levels of DHEA can mean that the adrenal glands are increasing
DHEA production on response to stress or high glucose levels,
or that the ovaries are increasing the production of DHEA as
part of the PCOS cascade.
High levels of DHEA are often seen years before a female
develops metabolic syndrome and should be used as a risk factor
marker for insulin resistance.
Low levels of DHEA
are seen in evolving “Adrenal Gland Fatigue" (hypoadrenia).
As acute stress becomes more chronic, the constant demand by
the body for adrenal gland hormones begins to wear out the
adrenal glands and DHEA and cortisol levels fall.
It is for this reason that DHEA is often measured in
combination with cortisol levels. Cortisol is a hormone
produced by the adrenal glands in response to stress and blood
sugar levels. Cortisol secretion has a diurnal rhythm.
Normal cortisol levels should be highest one hour after waking
in the morning and drop gradually throughout the day. Measuring
the diurnal rhythm with 4 cortisol levels throughout the day
gives a very accurate measure of adrenal gland function and
their ability to cope with stress.
Adrenal fatigue occurs in stages. The stage at which a patient
is at can be determined by looking at the diurnal cortisol
graph and DHEA levels. Symptoms of evolving adrenal gland
fatigue include fatigue, sleep issues, inability to cope with
stress, anxiety, nervousness, irritability and allergies.
Hypothalamic
Pituitary Axis (HPA) Dysregulation is due to chronic stress
with the resultant excess cortisol production and down
regulation of cortisol receptors in the hypothalamus. In
other words the negative feedback loop that normally shuts
down the production of ACTH release is blunted and cortisol
production by the adrenal glands is uncontrolled. If this
continues, hypoadrenia always evolves. The symptoms of HPA
and hypoadrenia are essentially identical but salivary
testing easily distinguishes the two. This is crucially
important as treatment of each can be very different.
Measuring cortisol
and DHEA levels will also diagnose complex diseases such as
Addison’s Disease and Cushing’s Syndrome. Addison's disease
occurs when the adrenal glands do not produce enough of the
hormones cortisol and DHEA.
The disease is also called adrenal insufficiency, or
hypocortisolism. It has however, no relationship to end stages
of “adrenal gland fatigue" described above. The two illnesses
have very different mechanisms of action.
Most cases of Addison’s disease are caused by autoimmune
destruction of the adrenal cortex. Symptoms include chronic
fatigue, weight loss, loss of appetite, muscle weakness, and
hyperpigmentation of the skin.
Cushing’s Syndrome
results in excessive production of cortisol by the adrenal
glands. Symptoms include rapid weight gain of face, trunk
and back of neck, hirsutism, depression, anxiety and panic
attacks.
