Adrenal fatigue
Adrenal extremes — could you be on your way to Cushing’s or Addison’s
disease?
by Marcelle Pick, OB/GYN NP

If you’ve read my articles before, you already know that our adrenal glands
are crucial to our survival and contribute enormously to our overall health and
vitality. When constant stress prevails or other health problems lead the adrenals
to work on overdrive, underdrive, or to eventually reach exhaustion, we can suffer
dramatically. At the extremes, there’s Cushing’s syndrome (an overproduction
of the stress hormone cortisol) and Addison’s disease (an underproduction
of cortisol). These conditions can be life-threatening, and will likely be diagnosed
and treated quickly. But there is a whole lot of adrenal imbalance in between that
is often missed.
What most women don’t understand is that their adrenal
imbalance symptoms can be treated long before they ever develop full-blown
adrenal disease — and this can make a profound difference to your whole life.
The problem is, unless you’ve already reached either end of the adrenal spectrum,
most well-intentioned conventional practitioners in the US aren’t trained
to help you. It’s so frustrating when I work with a patient on a plan for
healing her adrenals, but then she returns from her conventional practitioner
saying, “My doctor doesn’t believe in adrenal fatigue.”
Just because conventional medicine doesn’t have established protocols for
testing and treating adrenal imbalance, doesn’t mean it doesn’t exist. We’ve seen this
before with gluten sensitivity, which for many years was overlooked or dismissed
by conventional practitioners unless the patient had blatant celiac disease symptoms.
But gluten sensitivity is starting to be taken seriously — and I suspect that
in time conventional medicine will start to recognize adrenal imbalance as well.
The human body typically doesn’t just arrive at a diseased state; there are
pathways leading to it, with stations along the way. And in the case of Addison’s
and Cushing’s, you may be able to halt the progression by identifying adrenal
dysfunctions before they reach the crisis point. Let’s take a closer
look at these adrenal extremes, the gray zones between them, and how you can support your adrenal health and avoid
a crisis.
Hans Selye’s model of stress
In 1936, Dr. Hans Selye developed the General Adaptation Syndrome
theory, identifying 3 universal stages of coping with stress:
1) Alarm. At the first notion of stress, the body prepares for fight
or flight, where energy is diverted from all functions that are secondary to immediate
survival.
2) Resistance. Since the body cannot sustain itself in crisis mode
indefinitely, it enters a second stage when stress becomes more constant. The HPA
(hypothalamus–pituitary–adrenal) axis undergoes adaptations so it can deliver a
steadier stream of stress hormones.
3) Exhaustion. If stress goes on for long enough, the body reaches
this third stage, where it is depleted of its ability to respond to stress and begins
to give out.
In a healthy system, counterbalancing hormones are released once a threat has passed,
to signal your body to return to normal (homeostasis). Adrenal imbalance can develop
in response to prolonged periods of stress.

Opposite ends of the adrenal spectrum
Even way back when I was a student, I found it difficult to simply accept a diagnosis
and carry out the prescribed treatment plan without digging a little deeper. Instead
of simply taking a disease at face value, I’ve always wondered, How did this
patient get there? And Could we have stopped the progression?
It’s true that certain health issues beyond our control can cause Cushing’s
syndrome and Addison’s disease, but I’ve learned that there are also
many factors within our reach that influence them.
Cushing’s syndrome (also called hypercortisolism) is caused by long-term
exposure to high amounts of the stress hormone cortisol. A more comprehensive list
of Cushing’s symptoms can be found in the chart
below, but patients with this disorder often acquire some distinct features: their
faces are moon-like in shape, their bodies are very round in the middle, and they
sometimes have a fatty hump at the back of their necks. Patients with Cushing’s
can also feel anxious, irritable, or depressed. In other words, this syndrome truly
affects both the physical and the emotional. And most of what you’ll read
about the origins of Cushing’s explains that it is generally caused by taking
steroid hormones like prednisone (which is chemically similar to human cortisol)
for a long period of time. In other cases, there may be a tumor in the brain or
the adrenal gland causing the increased cortisol release.
But there are other patients who are simply producing too much cortisol in their
bodies. If we look at common complications of Cushing’s — type 2 diabetes,
obesity, poorly controlled blood sugar, high blood pressure, and metabolic syndrome
— it’s clear to me that there is a connection between diet and Cushing’s.
And it makes sense, because when blood sugar spikes (as it does with refined carbs
and sugary foods), so does insulin, leading afterward to a dramatic drop in blood
sugar. In this situation, the adrenal glands must pump out cortisol to mobilize
glucose into the blood stream, so we can function. If this is happening over and
over again, you can see how cortisol could be overproduced. Cortisol is produced
in abundance when we’re experiencing any kind of stress, so it may not be
just an energetic crisis like what I’ve described above, but also psychological
or emotional stress influencing your risk for hypercortisolism.
Conditions associated with a higher risk of adrenal insufficiency
- Hypothyroidism
- Type 1 diabetes
- Pernicious anemia
- Trauma (head trauma, surgical trauma, sports injury, bleeding)
- Pregnancy
- Infectious diseases (including tuberculosis and candidiasis)
- Coagulation disorders
- Liver disease
- Tumors (especially pituitary and adrenal tumors)
- Anxiety disorders and atypical depression
- Alcohol abuse
Reference
At the other end of the spectrum, Addison’s disease
(also called hypocortisolism) is a disorder where the adrenal glands don’t
produce enough cortisol and other glucocorticoids. There are several ways to get
to this point as well. Most conventional practitioners will explain that Addison’s
is caused by either a lack of ACTH (adrenocorticotropin), which is the
pituitary hormone that stimulates the adrenal glands to pulse out cortisol, or a
localized problem, such as a tumor, surgery, or infection causing a breakdown in
the messaging to release cortisol. There’s also the possibility of the body’s
own immune system attacking the outer cortex of the adrenal glands (called autoimmune
adrenalitis).
Yet, as you can see from the list to the right, several other common conditions
can predispose us to adrenal insufficiency, like hypothyroidism, diabetes, and anxiety!
And our on-the-go lifestyles don’t help. Very few conventional practitioners
in this country recognize adrenal fatigue, or the more serious adrenal
exhaustion, which is basically “subclinical Addison’s,”
the state bordering Addison’s disease. But adrenal fatigue is something I
see in my practice all the time. Adrenal fatigue expert Dr. James Wilson explains
that there are four basic patterns leading to adrenal fatigue:
1) A prolonged period of resistance, finally giving way to adrenal fatigue.
You could say this is typical of “the stoic,” who bears up to everything
life has to throw at her but blows out her adrenals with a final life stressor —
“the straw that broke the camel’s back.”
2) A single life blow, major or minor, followed by chronic, ongoing adrenal
fatigue.
This pattern might be typical of those whose adrenal reserve was weak to begin with.
You may have heard someone say, “Poor thing, she never got over x…”
3) Cycles of recurrent adrenal fatigue, with intermittent but partial recovery.
This is a characteristic pattern of those whose constitution is strong. They may
give and give, but despite warning symptoms refuse to change. Such cycles can also
result from forces of circumstance — “a series of unfortunate events.”
4) Slow decline into adrenal dysfunction.
In this case, life’s urgent stressors just grind down a person’s resistance
to stress gradually, to a point where they end up with subclinical Addison’s.
The great news is that in all the above cases of adrenal fatigue, recovery is possible.
I’ve helped many women through the process of healing adrenal imbalance. Yes,
it takes some time and commitment. But not only can we prevent a much larger adrenal
crisis from developing, every aspect of your life will brighten up when your adrenals
get the support they need. After all, these are the organs that help you deal with
stress!
Signs and symptoms of adrenal dysfunction
You’ll find a chart below listing some of the symptoms that come with various
adrenal dysfunctions. Cushing’s lies at one end of the spectrum and Addison’s
at the other. The two way-stations in between are not generally recognized by conventional
medicine. Know that there is a wide range of scenarios and patterns in adrenal imbalance
between the two extremes. If any of these signs
and symptoms of adrenal dysfunction look familiar to you, you can read more
about adrenal health on our website or schedule an appointment with a functional
medicine practitioner.

What conventional lab tests won’t tell you
Conventional adrenal function tests
Cushing’s is generally diagnosed by reviewing several lab tests, including:
- 24-hour urinary free cortisol level
- midnight plasma cortisol and
- late-night salivary cortisol measurements
- low-dose dexamethasone suppression test
- dexamethasone-CRH (corticotropin-releasing hormone) test
An Addison’s diagnosis is confirmed with:
- ACTH-stimulation test
- CRH-stimulation test
Reference
Unless you visit your practitioner with classic Cushing’s or Addison’s
symptoms, your adrenal function probably won’t be tested. And if you are tested,
be mindful of the fact that the conventional lab tests in the United States are
set up to detect disease states. So a woman whose numbers don’t fall at the
extreme ends of the bell curve will be assumed normal, and the practitioner will
likely move on to another possible diagnosis. What’s troubling to me as a
functional medicine practitioner, is that there are thousands of people who live
their lives struggling with subclinical adrenal dysfunction and are unable to get
any help.
If I suspect an adrenal imbalance or adrenal insufficiency in a patient, I measure
cortisol levels at several points in a 24-hour cycle with a panel of saliva tests.
We do this because cortisol output has a diurnal rhythm to it, where it is typically
elevated in the morning to help us get moving, then slowly declines throughout
the day to help us prepare for sleep. With this style of testing, I can often detect
and address adrenal imbalance before a major problem has occurred.
Blood pressure readings can also give us clues about adrenal insufficiency. If your
blood pressure drops dramatically, with dizziness and lightheadedness when you stand
up from a seated or lying-down position, this may be a sign that your adrenals are
compromised.
If more practitioners were mindful of the need to investigate variations in adrenal
function instead of focusing on the extremes, I believe we’d see a much more
vital, energetic, and stress-resilient population. Because your adrenal glands serve
many crucial and secondary functions alike, healing adrenal imbalance can make a
tremendous difference in your whole-body health, including your thyroid, libido,
and ability to face whatever challenges and opportunities life may send your way.
The road to Addison’s and Cushing’s — you’re riding up front
What your practitioner may not tell you is that your adrenal health rests primarily
on quality nutrition and lowering stress. This is good news, because we can do something
about these two aspects of our lives! I tell my patients that if we can address
what they’re eating and manage their stress, they will be on their
way to happier, healthier lives. I promise.
Science tells us that cortisol is released in higher amounts when we are anxious
or under stress, and this can be any kind of stress. Many women don’t understand
that diet is another form of stress in the body. If insulin and blood sugar are
consistently on a rollercoaster because of highly refined carbohydrates and sugar,
cortisol is responsible for leveling things out. After a while, the adrenals will
tire of having to come to the rescue. Add emotional and psychological stress on
to this and it only makes things worse. Over time, your body can go from a state
of cortisol dominance to the eventual adrenal-exhausted state of low cortisol.
You can make real changes in your life that support your adrenal glands before something
goes wrong. Easy, natural steps you can take today include
eating for your adrenals and exploring
herbs to support your adrenals.
On our way to adrenal awareness
I’ve been in practice a long time, and I’m slowly starting to see more
and more endocrinologists pay attention to the adrenal glands. The author of a recent
New England Journal of Medicine article urged clinicians to become more
aware of the “growing list of causes and predisposing factors” that
lead to adrenal insufficiency. It is my hope that in the near future, conventional
medical circles will acknowledge the full adrenal spectrum, rather than two isolated
conditions. Let’s face it: life is becoming increasingly stressful in terms
of low-quality food, 24/7 technology, and less time to unwind and relax, so I’m
seeing more and more adrenal imbalance in my practice. It’s time for us to
slow down and take care of these tiny glands — when we do, our bodies will
thank us!
