How Did We Get Here?
Menopause is not a pause. While menopause literally means
"cessation of menstrual periods," for most women it defines the most traumatic
part of their lives. It forces them to confront the inevitability of aging. It
is not a glorious transition; it is not a time when women feel free and
empowered.
As one of my patients put it, "The menopausal experience
changes one's sense of self. Lots of little things go wrong and then suddenly,
one day, you find you are not the same person anymore." It is the accumulation
of many symptoms and changes that become progressively less manageable and end
up all too often with disastrous consequences. These disastrous consequences
affect more than forty-three million women today, along with twenty-one million
women who will be reaching their menopausal years in the next decade. The
research on menopause is limited, solutions scarce, information contradictory.
In 1993, the National Institutes of Health started a ten-year study to compare
hormone replacement therapy with diet, exercise, and calcium supplementation in
the prevention of cancer, heart disease, and osteoporosis. The results of this
study will not be available until 2005 at the earliest. Who has time to wait
until then? Definitely not the millions of women suffering from symptoms of
hormone imbalance today. Those women have options; all they need is an
understanding that menopause is simply another changeit does not happen
overnightit's another transition in the continuum of change in our lives.
Indeed, long before we reach the point of being overwhelmed
by the symptoms of menopause, long before we feel totally betrayed by our
bodies, little by little, one symptom at a time, menopause unfolds over more
than thirty years. The key to preventing the serious and devastating problems
created by menopause is found in understanding the correlation between these
symptoms we experience at all times during our lives and the hormone imbalance
that causes them. The symptoms begin when we are in our teens, and they follow
us throughout our lives with incredible tenacity. Let's look back in time and
see when they begin and what causes them to occur. Once we realize that these
symptoms are part of our lives at all ages, we can uncover their root cause. If
we connect our symptoms to the particular type of hormone imbalance that causes
themregardless of agethen we can treat the problem and prevent it from
recurring or getting worse. In The Hormone Solution, I'll provide you with a
comprehensive solution for the treatment of the normal changes that affect
women (and men) throughout their lives.
Does the following sound familiar? You're thirteen. You are
an accomplished athlete and a tomboy. You refuse to wear dresses even when you
go to church. Your mother is concerned because all your friends have gotten
their periods while you show no signsno breast buds, no perspiration odor, no
pubic hair. Your mother takes you to the doctor, and your blood tests, physical
examination, and CT brain scan are normal. Nothing changes for another three
years. And then, over a period of six months, you become a girlyou stop being
a tomboy, you grow breasts, get your period, and start blushing when you meet a
boy.
Or maybe this rings a bell? You're twenty-four. You just had
your second child. The pregnancy was uneventful, and your baby is beautiful and
healthy. Although you have plenty of support from your family and friends,
you're getting depressed. With each passing day, your family helplessly watches
you lose interest in the baby and yourself. You finally give in to your
husband's pleas to go see a doctor. You're diagnosed with postpartum
depression.
Perhaps you're at a later stage: You remember when you were
thirty-two and would come home from work and finally finish with the husband,
the kids, and the phone calls. Those were the days when you were done with
another long but rewarding day and couldn't wait to hit the sack. You'd crawl
into bed and fall asleep within a minute. You slept as if you were in a coma.
Now, fifteen years later, you're forty-seven. Your job is secure, your kids
have their driver's licenses and are ready to go to college, your husband and
you have stopped bickering over the position of the toilet seat cover, and just
when you thought things should be getting easier, something very strange has
happened.
By 10 p.m., you are so exhausted you barely make it through
brushing your teeth and applying your five different antiwrinkle creams
guaranteed to take ten years off your face. You're extremely tired but you
dread getting into bed because you know what follows will be a torture you
never believed possible. And yet, you have no choice, you know you need the
rest. So you go to bed, and thankfully, you fall asleep: but not for long.
Suddenly, it feels as though a bolt of lightning has shot through you. You jump
up, it's 2 a.m., you're lying in a pool of sweat, and your body temperature
feels high enough to boil water. The sheets are twisted around you; your heart
is pounding hard. You're fairly sure you aren't having a heart attack because
the same thing has happened every night for months now. Suddenly, you realize
you have to pee so badly that you're not sure you can make it to the bathroom.
Holding on to the walls, you reach the toilet and pray this activity won't wake
you up too much. You return to bed and pull the blanket to your nose as a cold
shiver runs through your body. You close your eyes and try not to think of the
perspiration-soaked sheets, which have now turned to ice. You look around and
wonder why the man lying next to you is sleeping soundly. You lie awake for
hours desperately wanting and needing to sleep. When the alarm goes off in the
morning, you want to die. You cannot believe it's time to start another day
feeling this way.
What happened? What has changed between the time you were
thirteen and forty-seven?
The answer is simple: Your hormones. Let's assume that our
lives are a jigsaw puzzle. The pieces that make up the puzzle are our hormones.
Having all the pieces isn't enough. What we must know is how the pieces fit
and, once they do, how to keep the puzzle together. When you're thirteen, you
clearly lived in a world where the puzzle fits neatly and flawlessly. While
your hormones may not follow the expected moldbreast buds at eleven, menstruation
at thirteenyou're fine. Your hormones balance themselves and find the happy
medium to keep you healthy and normal. At twenty-four, postpartum depression
represents a common example of hormone imbalance of a more severe type. By
forty-seven, the problems appear insurmountable. Our hormones, the pieces of
the puzzle, begin to come apart, and we either figure out how to fit them
together again, or we become sick, we feel old.
The Hormone Solution will teach you how to identify each
piece of the puzzle, make the pieces fit, and give you the secret to keeping
the puzzle intact for years to come. I will give you the background you need to
build the foundation that keeps your body and mind in perfect balance. If you
understand how your body works, you can help forestall illness, get rid of
unwanted symptoms, and restore your energy and vitality.
This may sound like a tall order, but I promise you it's
not. I won't waste your time with intricate, medical detail. While
understanding the complex physiology of hormones may be interesting, it's their
application to our personal lives that really matters.
The Hormone Story
Hormones are products of living cells that circulate in our
bodily fluids and produce specific effects on the activity of other cells far
removed from the organs where the hormones are made. They stimulate or inhibit
the actions of cells everywhere in the body. No organ is left untouched by the
actions of hormones. Hormones, however, cannot be seen with the naked eye, and
this situation makes them very difficult to understand.
Endocrinology: The Study of Hormones
In the 1970s, when I went to medical school, endocrinology,
the medical subspecialty involved in the diagnosis and treatment of diseases of
hormones and the glands that make them, was not a popular course. It was
complicated, it dealt with intangibles, and few students could grasp it.
Hormones were complex structures, critical to the proper function of the human
body, yet impossible to pin down. Even when dealing with diseases, they were
difficult to evaluate by our medical testing methods. Everywhere you turned, be
it in illness or in health, you saw their effects on men and women, yet our
profession could not control them.
Blood tests were inadequate and cumbersome, and no radiologic
techniques for evaluating the actions of hormones existed. Testing pituitary
(master gland) function was hell for both patient and physician. We tested only
for disease. The tests were complicated, they took days to perform, the
patients were invariably very sick, and the results were difficult to
interpret. Laboratory and clinical research was intricate and laborious, and
the information published in the scientific literature was mostly esoteric,
pertaining mainly to animals and not humans. As a result, few medical students
chose endocrinology as their career.
Even now, endocrinology, with its focus on diseasediabetes,
thyroid, pituitary, and genetic hormone imbalancesis not a popular specialty.
There has never been a glut of endocrinologists, which very well may be the
reason why the study of hormones and how to balance them has become an area for
wellness experts and anti-aging specialists.
The Importance of Hormones
Hormones run through our bodies with great speed. They have
the power to make us feel well, but they can also wreck our lives. There are many types of hormones, all
with important roles in keeping us balanced and healthy. They balance our sugar
level, instruct our cells to generate energy, keep our calcium level normal and
our hearts beating regularly, and help our liver detoxify our system even after
a five-martini night. Even with twenty-six years of clinical medical experience
and my present focus on the study of hormones, I am still utterly fascinated by
their impact on the human body. Although there are a lot of known hormones
controlling our body's functions, I believe one particular hormone group reigns
supreme: the sex hormones. These are estrogen, progesterone, and testosterone.
They determine our gender; they are responsible for our outlook on and
reactions to life, how we age, and ultimately how long we live.
The Primitive Master Gland: The Hypothalamus
Hormones are produced by lots of organs, but their
production and actions are always rigidly controlled by the master glandthe
hypothalamus (hi-po-THA-la-mus, a pinhead structure buried in the middle of the
brain, above the pituitary gland). The hypothalamus literally supervises the
synchronization of hormone release. We don't know how the hypothalamus got to
be in charge of all hormone balance. Its mysterious function has been studied
for many years. The most commonly accepted belief is that the hypothalamus is a
very old organ linked to early animal evolution; it was allegedly there before
the pituitary existed and before sexes were differentiated. Its role was to
control basic body functionsheartbeat, breathing, digestion, reproduction,
excretion. Throughout evolution, the hypothalamus has maintained its
controlling role by making the one hormone that coordinates all sex hormones:
gonadotropin-releasing hormone (GnRH).
Through a system of blood vessels inside the brain, this
hormone goes directly to the pituitary and stimulates it to release its own set
of hormones with the final role of modulating end-organ sexual hormone production.
"End organ" refers to the ovaries, testes, and adrenal glands; the hormones
they produce are estrogen, progesterone, and testosterone, among others.
Remarkably, this one hormone (GnRH) monitors the production and effects of
hormones made by the pituitary, the ovaries or testes, and the adrenals. This
remarkable feat is the main reason why the hypothalamus is one of the key
pieces in the hormone puzzle.
Along the evolutionary ladder, a new organ developed between
the hypothalamus and the other organs (heart, lungs, stomach, ovaries, testes,
adrenals). That organ is the pituitary.
The Modern Master Gland: The Pituitary
Below the hypothalamus, buried in the middle of the brain,
lies the pituitary gland. While we consider the hypothalamus a primitive, old
remnant of an antique glandular system, the pituitary is much newerthe
modern-age master gland. Arbitrarily divided by physiologists into anterior and
posterior portions, the pituitary produces a lot of different hormones. All
sex-hormone-releasing and -inhibiting factors are produced by the anterior
portion of the pituitary gland. It is there, in an area of a few millimeters,
that the headquarters of hormone regulation are located.
The anterior pituitary is in charge of stimulating or
blocking the release of the principal sex hormonesestrogen, progesterone, and testosterone. This is
accomplished through the actions of two hormones secreted by the anterior
pituitary: follicle-stimulating hormone (FSH) and luteinizing hormone (LH). FSH
and LH are directly responsible for cycling the production of estrogen and
progesterone by the organs that produce them (ovaries, adrenals, and corpus
luteum). FSH stimulates estrogen production, while LH stimulates progesterone
production. FSH and LH work together to balance estrogen and progesterone
levels. Another sex-related hormone produced by the pituitary, prolactin is
released primarily after a woman gives birth. Its role is to stimulate the
breast to produce milk and to shrink the size of the uterus back to normal.
How Do FSH and LH Work?
Let's take an average twenty-eight-day menstrual cycle, when
you aren't pregnant. We'll start with day 1. You have just started your period.
Your estrogen and progesterone levels are practically nil. The lack of hormones
in your system is what has induced you to get your period.
GnRH from the hypothalamus and FSH from the pituitary are
excreted in response to the level of estrogen circulating in your bloodstream.
On day 1, as the blood washes against the hypothalamus and anterior pituitary,
there's practically no estrogen in it. The hypothalamus thus sends out its
hormone GnRH to wake up the pituitary. The receptors on the cells that make up
the anterior pituitary gland respond to the rise in GnRH and the lack of
estrogen in the bloodstream. Their response is to release FSH into the
bloodstream. The presence of FSH stimulates the ovaries and adrenals to start
making estrogen. For the following ten days of the normal cycle, the anterior
pituitary gland will be pouring out FSH to stimulate the ovaries to make
estrogen.
Indirectly, the high levels of FSHtogether with the
now-rising levels of estrogenare responsible for another important job.
Remember that FSH stands for "follicle-stimulating hormone." Its job is to
stimulate the formation of the follicle and the maturation of an egg. In one of
the ovaries, an egg has been identified. This egg (ovum) will become mature
over the following ten days. It is this egg that will be expelled from the
ovary at the time of ovulation, fifteen days before the end of the cycle. If
fertilized by a sperm, this is the egg that will become a baby nine months
later.
FSH and estrogen prepare the egg for ovulation. This part of
the cycle is called the follicular phase. It is during this phase that the
ovaries are making estrogen and testosterone to help the egg ripen. As it
ripens, the egg is surrounded by a protective bubble, the follicle, which
develops as the egg matures. Once mature, the egg is expelled from the ovary on
ovulation day. The follicle is left behind in the ovary and it becomes the
corpus luteum, which produces progesterone.
As this scenario unfolds, the increased levels of estrogen
produced by the ovaries and follicle are now reaching the pituitary and sending
a new message to the master gland: "We have enough estrogen here to go ahead
and ovulate."
If the pituitary reads the message correctly, it starts
releasing LH (luteinizing hormone). LH promotes ovulation. Within ten to twelve
hours of the spike of LH in your bloodstream, you ovulate. LH stimulates the
production of pro-gesterone, the thinning of the wall of the ovary, the
expulsion of the egg from the ovary, and the beginning of the luteal phase of
the cycle. Once ovulation has occurred, fifteen days before the start of the
next period, LH levels drop rapidly.
While FSH is around for the better part of the cycle,
stimulating the production of estrogen and its attendant effects, LH comes out
for just a short time, in spurts or pulses. LH production is turned off by the
increasing levels of progesterone.
For the last two weeks of the cycle, estrogen and
progesterone production are in balance to prepare the body for pregnancy.
Progesterone is made by the corpus luteum, the name given to
the follicle once the egg has been expelled from the ovary. The corpus luteum
then becomes an independent organ responsible for further support and
preparation of the egg for fertilization. The progesterone made by the corpus
luteum prevents other eggs from maturing, and keeps the uterine lining ready for
implantation. More than 90 percent of the body's progesterone is made by this
short-lived organ. If you get pregnant, the corpus luteum thrives and makes
literally gallons of progesterone to nurture and sustain the fetus during the
pregnancy. If you don't get pregnant, the corpus luteum shrinks and dies. With
its demise, progesterone productionand thus circulating progesterone
levelswanes. The cycle has ended; you get your period. The fall of estrogen
and progesterone levels is sensed by the hypothalamus. This signals the start
of a new cycle, and the hypothalamus heralds it by secreting GnRH.
The cycle repeats itself every month until you either get
pregnant or stop ovulating.
Estrogen, Progesterone, and Testosterone
Today, in the arsenal of medical knowledge, there are many
sex hormone precursors, multiple "almost sex" hormones, and lots of wannabe sex
hormones. There are only three true end-organ sex hormones: estrogen,
progesterone, and testosterone. Both men and women have all three. The difference
between men and women lies in the varying concentrations of these hormones
circulating in the bloodstream.
Estrogen and progesterone are the dominant hormones in
women. The dominant hormone in men is testosterone. A significant shortcoming
in our understanding of hormones is the belief that estrogen, progesterone, and
testosterone act independently of one another. The truth is that unless we
totally incorporate into our understanding the inseparability of the three sex
hormones, we cannot solve the problems caused by imbalances in their levels.
Estrogen
In women estrogen is made in the ovaries, the follicle
around the ovum, the adrenal glands, and the fat cells. Estrogen is not just
one molecule, but rather a group of molecules. The three main estrogen
molecules are estriol, estradiol, and estrone.
Estradiol (E2). Estradiol (es-TRA-di-ol) is the most
active form of estrogen made by our ovaries, adrenals, and fat cells as we get
older. Estradiol directly affects the functions of most of our body's organs.
Practically every cell in our body houses on its surface receptors for
estradiol. This means that estradiol can directly attach to every cell in our
body and influence its function. This is the way estradiol affects organ
function directly.
Estriol (E3). Estriol (ES-tree-ol) is the weakest and
least active form of estrogens. It is mainly made by the placenta. It attaches
to cell receptors making up hair, nails, skin, and mucosal membranes. It
affects primarily the vaginal walls and has little effect on the heart or
bones. In nonpregnant women, some estriol is made in the liver in small doses.
Estrone (E1). Estrone (esTRONE) in women is made after
menopause primarily in fat cells from testosterone derivatives
(androstenedionean-dro-STENE-di-own) and also in the ovaries. While most data
on estrone have been obtained from animal studies, human studies have shown
that overweight older women have high circulating levels of estrone. A European
study revealed higher levels of circulating estrone in women with breast
cancer.
When we refer to estrogen, we refer to its three components
as one. At times, this attempt to simplify creates errors in separating the
individual functions of its components. Although their combined actions present
as one in what we know as estrogen, its component molecules have different
potencies. For now, just remember that when I'm speaking of estrogen, I'm
referring to all three components (estriol, estrone, estradiol) as one, unless
otherwise specified. When I address treatment with natural hormones, however,
I'll be separating the three estrogen molecules.
With the progression of the aging process, the ovaries stop
producing estrogen on a regular basis, and the main source for the production
of estrogen becomes the adrenal glands. Unused testosterone is also transformed
into needed estrogen, and even estrogen stored in fat cells is called to
action. Estrogen and progesterone are designed to balance each other, to keep
each other in check.
We cannot live in a healthy state without their balanced
presence in our bodies. As we begin to examine their individual effects, keep
in mind that at no time does estrogen or progesterone act independently, in our
body.
Estrogen makes everything grow. The positive effects of its
action are that it:
Makes the lining of the uterus grow, to prepare for
pregnancy.
Helps the breast tissues grow, in preparation for making milk.
Causes the ovum to mature inside the ovary, to prepare for ovulation.
Supports the growth of the follicle where the egg matures.
Promotes the growth of the fetus.
Keeps the vagina, the vulva, and the cervix well developed and moisturized.
Promotes growth of underarm and pubic hair, and pigmentation of the nipples.
Stimulates body fat accumulation, to help the fetus grow.
Prevents bone destruction by bone-destroying cells (osteoclasts).
Protects the body from hypertension by relaxing the lining of blood vessels.
Stimulates the production of lipoprotein lipase, an enzyme that breaks down fat. The result is low cholesterol levels and a healthy balance between good (HDL) cholesterol and bad (LDL) cholesterol.
Lowers insulin levels.
Induces relaxation of blood vessels in the circulation in
general, and the heart in particular.
The negative effects of the growth induced by estrogen
unopposed (acting alone), without the balancing effects of progesterone, are:
Increased accumulation of body fat.
Increased water and salt retention.
Interference with normal insulin release and blood sugar
control.
Increased risk of overgrowth of endometrium (lining of the
uterus).
Increased risk of overgrowth of breast tissue.
Increased risk of anxiety and irritability.
Increased risk of headaches.
Increased risk of gallbladder disease.
Increased incidence of blood clot formation.
Progesterone
Progesterone is made primarily by the corpus luteum (the
follicle transformed after ovulation), and is a precursor to most sex hormones.
Progesterone comes into action in the middle of the normal menstruating woman's
cycle.
Stimulated by the release of LH (luteinizing hormone) in the
form of pulses by the pituitary gland, progesterone is absolutely crucial to
the survival of the ovum once fertilized. When pregnancy occurs, progesterone
production increases rapidly and is taken over by the placenta. If the woman
does not get pregnant, the corpus luteum shrinks, progesterone production
falters, and menstruation arrives.
Progesterone is the precursor, or parent, of estrogen in the
ovaries. The adrenal glands and testes also manufacture it. Progesterone is the
precursor of testosterone, all androgens, and other adrenal hormones, making it
extremely important for reasons far beyond its sex hormone role.
Progesterone's functions on the estrogen-progesterone team
are to:
Prepare the endometrium for implantation of the fertilized ovum.
Ensure survival of the fetus in the uterus.
Prevent water retention.
Help use fat for energy at the cellular level.
Serve as a natural antidepressant.
Create a calming effect on the body.
Help restore regular sleep patterns.
Help keep insulin release in check and maintain even blood
sugar levels.
Prevent overgrowth of the endometrium.
Prevent breast tissue overgrowth.
Maintain sex drive.
Maintain normal blood-clotting parameters.
Protect against fibrocystic breasts.
Progesterone's negatives are few and easily balanced by
estrogen:
A sedating effect.
Increased spotting and changes in bleeding patterns.
Bloating, when taken in large quantities.
Gastrointestinal discomfort.
Acne.
Hyperpigmentation of facial skin when exposed to sunlight.
Testosterone
The classic male hormone, testosterone is the third of the
sex hormone trio. Made primarily in the testes and adrenals in men, and the
adrenals, ovaries, and corpus luteum in women, testosterone is part of a class
of hormones called androgens. These hormones have primarily masculinizing
effects. Like estrogens, when we speak of androgens (AN-dro-gens), we include
more than one hormone: testosterone (tes-TOS-te-rone), androstenediol
(an-dro-STENE-di-ol), dihydrotestosterone (DI-hy-dro-tes-TOS-te-rone),
androstanediol (an-dro-STANE-di-ol), androstenedione (an-dro-STENE-di-own), and
dihydroepiandrosterone (DHEA)(di-HY-dro-ep-i-an-dro-STER-one).
The most important role of testosterone is to provide male
characteristics. Although this may appear straightforward, testosterone functions are of significance to women as well.
Testosterone helps to:
Promote muscle strength and exercise endurance.
Improve libido.
Increase energy levels.
Improve sense of well-being.
Increase body hair production.
Produce enlargement of the penis and testes as well as
clitoris.
Improve sexual desire and fantasy.
Improve bone density.
The negative effects of testosterone are due to overproduction
or intake through either testosterone supplementation in pharmaceutical
formulations or unsupervised androgen consumption. The side effects are similar
to those of estrogen dominance, since testosterone transforms into estrogen
when it's overabundant. These side effects include:
Male pattern baldness.
Increased facial hair.
More aggressive behavior.
Higher cholesterol levels.
Too much clitoral enlargement.
Involution of testes and penis.
Growth of breast tissue in men.
We are only now starting to appreciate the importance of
testosterone in men and women. While the balance of estrogen and progesterone
is highly dependent on a cycle, we don't yet know how the balance of
testosterone fits. As the story of hormones unfolds, I'm sure much more will
come to light about testosterone.
Here, then, is the skeleton of hormone information I'll be
building on.
Hormones are intimately involved in every body function. The
amounts of hormones secreted are controlled by two glands in the brainthe
hypothalamus and the pituitary. Hormones are produced by the sex organs: the
ovaries, testes, and adrenal glands. There are three sex hormones: estrogen,
progesterone, and testosterone. Their actions are interconnected and are both
positive and negative. The balance and interaction among the sex hormones
determine the presence or absence of symptoms.
In the chapters that follow, I promise you insights that can
change your life for the better.
