Adrenal
Exhaustion
(Chapter 11 from Optimal Wellness)
As
our body's primary shock absorber, the adrenal glands determine
our response to stress. In this chapter, we will discuss adrenal
function and review the critical roles the adrenals perform to maintain
and safeguard our health. We will list the causes, signs, and symptoms
of adrenal exhaustion, cover medical testing, and finally present
a program for adrenal restoration. Let's begin with the case history
of Barbara, one of my patients.
Barbara
The first thing Barbara said
as she sat down in my office was, "I am totally exhausted."
A thirty-eight-year-old grade school teacher, she was barely able
to meet the demands of her work. Barbara was nearly desperate in
her plea for help. She told me that by the end of each school day,
her muscles and joints ached, her throat hurt, and she would develop
a low-grade fever. She couldn't even imagine having the strength
to prepare dinner for her family, or keep house. Fortunately, her
husband did all the domestic activities. The elder of their two
children pitched in as well.
When Barbara was able to get nine
hours of sleep, she would arise in the morning with the feeling
that if she pushed herself hard enough, she could manage through
the day. But she felt hardly any joy, spontaneity, or creativity
qualities she considered essential to teach and to parent. For this
reason especially, she was depressed, for she was falling far short
of her expectations. But she was depressed all the time anyway,
she said, even if she'd had a rare good day at school and everything
was going well in her family.
If anything out of the ordinary happened-like
having a cookie, having a pleasant dinner with friends, staying
up past 10:00 pm, shopping for groceries, or making love with her
husband-then her usual end-of-the-day symptoms would be even worse.
She usually needed several days or more to recover. If she drank
milk or orange juice, she would suffer from migraine headaches-sometimes
she'd get them regardless. Wheat would drastically increase her
fatigue, and she would get ill from certain perfumes as well as
from automobile exhausts.
As a result of these symptoms, Barbara
attempted to control each day. She had absolutely no reserves to
deal with unforeseen events. She said she couldn't continue on this
way. If she didn't get some relief soon, she was going to have to
take a medical leave of absence from her work.
I asked Barbara when she last felt
well. She replied that she'd been functioning fairly normally until
eighteen months before, when she'd been diagnosed with mononucleosis.
She never seemed to recover fully from the mono, she continued,
and it was in the following months that her current symptom picture
began to develop. After a year of not getting any better, she was
treated with an antidepressant. This medication had given her a
little relief, but the overall effect was not substantial.
Barbara had been on the antidepressant
for several months when I saw her for the first time. After hearing
her out, I questioned her about her earlier history. Her second
child had been born nine years before her arrival in my office,
a colicky and finicky baby who kept Barbara up many nighttime hours
with her crying over an eighteen-month period. To make matters worse,
when her son was just over a year old she'd been in a motor vehicle
accident and suffered a whiplash injury to her neck that required
months of physical therapy. Three years later, when it seemed that
life was finally beginning to settle down to normal, a lengthy and
nasty legal battle was sprung upon them involving her husband's
ex-wife. These difficulties were not yet over when Barbara suffered
a herniated disk in her lower back, which once again necessitated
months of physical therapy.
When
the Battery Runs Down
Everyone encounters stress in their
lives. However, when the intensity and chronicity of stress surpasses
the level beyond which an individual can cope, something's going
to break down. If you race a horse too frequently, if you keep running
and whipping her when she's tired, very soon she won't be able to
perform at all. If you keep your headlights on all night and run
down your battery, the only way to get your car going is by a jump
start. But if your battery is too depleted, even a jump start won't
do the job.
It wasn't surprising, with years of
continual stresspregnancy and lactation, sleep deprivation,
injuries, illness, overwork, emotional anguish, and anxietythat
Barbara lost her strength and her health. The events of her life
had forced her to keep performing beyond her limits. She never seemed
to get enough of a break to rest and build up her strength.
The
Adrenals: Our Body's Buffer Zone
It is our adrenal glands that buffer
stress and enable us to stand up to life's onslaughts. These glands
give us the capacity to perform and to adapt flexibly to the demands
of every day. It is also the adrenals that enable us to go beyond
our usual limits of endurance when needed and help us to recover
in a reasonable amount of time. Barbara had little capacity left
to perform, adapt, or recover. It was my strong suspicion that she
was suffering from adrenal exhaustion. I wasn't the first physician
who suspected a problem with her adrenal glands. Barbara had numerous
symptoms that fit the adrenal depletion picture in addition to nearly
nine years of continuous stresses of varying magnitude.
Check
the list of Adrenal Stressors on page 198 to see how your symptoms
and stress history stack up.
The
Function of the Adrenals
The adrenal glands, each approximately
the size of your thumb, sit on top of the kidneys (their position
is on each side of the spine approximately at the level of the lower
ribs). The adrenal cortex is central to this discussion. It is part
of the gland that synthesizes a number of hormones from cholesterol,
the very important ones being cortisol and DHEA (dehydroepiandrosterone).
The adrenal medulla is the part of the gland that secretes adrenaline.
Cortisol is akin to the drug cortisone (prednisone, prednisolone,
etc.), and although cortisone has developed an unfavorable reputation
for its well-known adverse side effects, our well-being depends
on the adrenals' ability to produce adequate amounts of cortisol.
DHEA is also essential. See the boxes on pages 200 and 201.
Testing
Barbara's Adrenals
One of Barbara's previous physicians
had tested her adrenal function with a blood cortisol level. The
sample was drawn at 8:00 A.M., which is when the level should be
at its highest of the day. It was a "low normal." Her
physician subsequently performed an ACTH (adrenocortiecotropin)
stimulation test. ACTH is the pituitary gland hormone that stimulates
and controls functioning of the adrenal cortex. The pituitary gland
is located in the brain and synthesizes several hormones, each controlling
one of the body's many endocrine glands. Injecting ACTH should nearly
double the blood cortisol level within an hour in an individual
with normal adrenal function. Barbara's adrenal function was therefore
declared "normal" because her cortisol level doubled.
The problem with the ACTH stimulation
test is that
it doesn't really measure the usual day-to-day functional capacity
of the adrenals. By this, I mean the effect the adrenals have on
an individual's everyday energy, stamina, mood, clarity of thought,
immune function/resistance, and circulation. An injection of ACTH
provides an abnormally high and very powerful adrenal stimulation,
much like the pituitary might produce under the most extreme levels
of fear or anxiety, such as running for your life.
This means the ACTH stimulation test
will therefore almost always be able to squeeze the double-normal
levels out of even very tired adrenals. The adrenal cortex would
need to be nearly nonfunctioning, as in Addison's disease, to fail
this test and gain adequate attention from most physicians. This
test recognizes only normal function or no function, nothing in
between. It is clearly not sensitive enough to recognize the spectrum
of diminishing adrenal function, which is where Barbara's and many
other individuals' adrenal function lies. Thus it is unable to explain
why they are not well.
Another problem with standard blood
cortisol testing is its lack of specificity for "free"
cortisol as opposed to protein-bound cortisol. It is only the free,
unbound fraction that is biologically active and is therefore the
only fraction that accurately reflects adrenal status. The standard
blood cortisol test measures both bound and unbound cortisol. If
the result is "low", you can believe it; if it is "normal,"
it can mislead you into thinking the adrenals are fine when in fact
they may be functioning far below normal.
In my experience, measuring free cortisol
and DHEA levels in saliva has proven to be the most dependable method
of assessing adrenal function. This test has enabled me to explain
why so many of patients have been unwell for r so long-the "walking
dead," as many of them refer to themselves. And it has given
me a base line from which to help these individuals return to the
"living" and rediscover their well-being.
I
utilize the Adrenal Stress Index
Test, which measures free cortisol at four specific times during
a day (8:00am, noon, 4:00pm, and midnight) and DHEA/DHEA sulphate
at the noon and 4:00pm collections. Salvia samples are collected
at these times during an individual's normal day-during real-life
conditions-without the added stress of being in a doctor's office
or laboratory. On the other hand, having blood drawn has been shown
to cause cortisol elevations all by itself, and thus interferes
with accurate adrenal assessment.
Comparing these four samples to the
norm and looking at the cortisol/DHEA ratio can reveal both overstimulated
and depleted adrenal states. Such information can pinpoint the most
effective treatment recommendations, whether diet/nutritional therapy,
herbal medicines, stress management, and/or pharmaceutical hormones.
Under stress, healthy adrenals will
respond by increasing the output of both cortisol and DHEA to higher
than normal levels. Such temporary adaptive elevations enable an
individual to maintain homeostasis and preserve health in the face
of stress. However, if stress becomes chronic, eventually the adrenals
can no longer maintain the production of extra DHEA. With continued
elevated levels of cortisol and falling DHEA levels, an elevated
cortisol-to-DHEA ratio ensues. This signifies an initial stage of
adrenal exhaustion and has potentially devastating effects on health.
These include:
Decreased levels of secretory IgA (mucosal antibodies)
-Increased absorption of antigens (foreign substances)
-Decreased natural killer cell activity
-Decreased levels of interleukin 2
-Decreased T lymphocyte counts leading to increased
susceptibility
to infections, allergies, autoimmune disease, and cancer
Reduces REM (rapid eye movement) sleep and therefore sleep
that is not restful or restorative
A catabolic state where tissue breakdown exceeds tissue
repair/building, which leads to muscle wasting, weight
loss, and bone loss/osteoporosis
Greater percentage of body fat and smaller percentage of
muscle mass; fat accumulation around the waist
Diminished insulin sensitivity and therefore reduced glucose
utilization at the cell level leading to elevated blood
sugar
levels and possibly diabetes
Salt and water retention, leading to edema
Elevated blood fat levels, levels, leading to atherosclerosis
People
whose test results show a significant cortisol elevation at midnight
commonly experience an endogenous, or biochemically induced depression
in contrast to one produced by circumstances. It also sometimes
correlates with insomnia. Figure
11-2 shows the results of Barbara's Adrenal Stress Index test.
Barbara's 8:00am cortisol level should
be at the highest of the day (between 13 and 23 nanomolars), giving
her a strong start and enabling her to meet the day's demands. What
is most striking here is the significantly low cortisol level of
4 at 8:00am. She also experienced a low level of 2 at 4:00pm and
a borderline low of 4 at noon. Considering Barbara's history-especially
her daily struggle to get out of bed, even with more than eight
hours of sleep-and the need she experienced to push herself all
day long, her uniformly low cortisol levels come as no surprise.
Over time, continued stress and lack of effective intervention usually
first results in the abnormally elevated cortisol/deficient DHEA
state, and later in Barbara's more deteriorated state of both cortisol
and DHEA depletion.
To help restore Barbara's depleted
adrenal glands, I recommended most of the measures on pages 203-205.
These make up the bulk of my adrenal restoration program.
Additional
Cortisol and DHEA
Besides the above primarily self-care
measures, individuals like Barbara with severe adrenal exhaustion
often require a prescription of small doses of cortisol in the form
of hydrocortisone. I recommend up to 20 milligrams a day in divided
doses. Such a dose is approximately half of what normal adrenal
glands produce every day. It has never, in my experience, produced
any of the common side effects caused by pharmacologic doses, usually
over 40 mg daily of hydrocortisone, the equivalent of over 10 mg
of prednisone.
If, like Barbara's, an individual's
DHEA is too low, or the cortisol/DHEA ratio is too high, supplemental
DHEA is often needed, I recommend individualized doses, gradually
working up to the desired level. For women this might be up to 10
mg twice a day; for men, up to 20 mg twice a day. Some of my patients
have required somewhat higher doses. If using the more absorbable
alcohol-based DHEA tincture, reduce the maximum doses by one-half.
In addition to its own functions,
DHEA can be converted in the body to estrogen. Too high a DHEA dose
in women causes breast tenderness or spotting between periods. DHEA
can also be converted into testosterone{the male hormone} and, in
women, too much DHEA can trigger acne and male pattern hair growth.
A woman's appropriate dose is one that brings the desired results
without any of the adverse side effects. Too much DHEA can suppress
cortisol production to abnormally low levels. Monitoring these hormone
levels with periodic follow-up testing is essential to assure adequate
levels and to safeguard against overdosing.
DHEA should not be taken routinely
by women who have conditions that can be worsened by supplemental
estrogen, such as endometriosis, fibroids of the uterus, or estrogen-sensitive
breast cancer. Nor should it be taken routinely by men for conditions
worsened by testosterone, such as prostate cancer. Although the
immune systems of these individuals with low DHEA levels could benefit
from increasing these levels, supplementing with any doses of DHEA
beyond physiologic levels carries potentially serious risks. Close
periodic monitoring of levels and supervision by a qualified health
professional are essential.
By supplying safe doses of cortisol
and DHEA to a body deficient in these essential hormones, an individual
begins to feel normal again, with strength and mental powers returning.
This "borrowed" health enables them to manage their stress,
and any other ailments they may be battling more effectively. This,
in turn, eases the demand on the adrenals, which allows these glands
a partial rest and gives them a chance to restore their strength.
These hormones also directly allow the adrenals to rest by lowering
the pituitary's ACTH stimulation to some extent. Just like a tired
horse, exhausted adrenal glands will only grow weaker if they are
continually overstimulated, overstressed, and whipped into action.
By providing safe, temporary small doses of hydrocortisone and/or
DHEA, this potentially damaging ACTH stimulation is lessened.
Once the adrenals are thus rested,
they can begin to restore their strength. Over time-four to twelve
months commonly-supplemental hormones can be slowly tapered and
discontinued as the adrenal glands start to function better on their
own again. However, this rejuvenation program is equally dependent
on a diligent maintenance of the adrenal restoration measures discussed
above, most especially stress management. Lifestyle changes are
an inherent part of bringing your body to a state of optimal wellness.
Avoiding excessive and prolonged hormone supplementation will also
help make successful weaning possible.
Aggravating
Conditions
There are many conditions that, if
present can be additional sources of adrenal stress and need to
be identified and treated in order to achieve the best outcome.
Food allergy, hypoglycemia, inhalant allergies, yeast overgrowth,
intestinal parasites, chronic sinusitis and other infections, and
chronic inflammation and pain are common drains on adrenal strength.
On the other hand, adrenal exhaustion will also render an individual
susceptible to some of these very same conditions.
An optimal wellness approach must
fully consider this cause/effect continuum and pinpoint all associated
conditions. Barbara, y adrenal exhaustion patient, was indeed suffering
from more than just one of the ten common denominators of illness.
My diagnostic evaluation of her condition also disclosed hypoglycemia,
food allergy, and yeast overgrowth.
However, I had evaluated enough patients
to recognize that for Barbara, the resolution of her adrenal status
was critical. The treatments for her other conditions could then
have a better chance of succeeding. Nevertheless, this isn't always
the case. I've had patients whose chronic sinusitis was the most
deep-seated condition, and it was only after resolving it that adrenal
depletion and other conditions could be successfully addressed.
Restoring the Adrenals:
A Golden
Opportunity for Stress Reduction
Stress abounds in our world today,
and our adrenals serve as shock absorbers to help protect our bodies
from the physical and mental wear and tear of our lives. But like
any gland or organ to our bodies, there's a limit to how much the
adrenals can withstand. Past a certain point, they will begin to
weaken and affect our health in very serious ways.
Without adequately functioning adrenal
glands, it would be difficult to feel or function anywhere near
your best. You'd be subject to a multitude of physical and mental
symptoms that your doctors might have a hard time pinpointing. They
might even tell you that it's all in your head.
If you have adrenal dysfunction you
can make a substantial improvement in how you feel with the self-care
measures outlined in this chapter. I cannot stress enough the critical
role stress management will play in you recovery. However, also
consider seeking the assistance of a medical professional to help
in adrenal assessment and restoration. The body's delicate balance
of hormones and chemical messengers needs skilled professional monitoring.
