Adrenal Fatigue or HPA Axis Dysfunction

What is Adrenal Fatigue?

Are you a type A personality? A high achiever? SuperMom? Do people wonder how you can manage to do so much in a day? Or how you do so many things so well? Are you under lots of stress? You may be at risk of (or are already experiencing signs of) adrenal fatigue.  It is also known in medical circles as HPA axis dysfunction.

Adrenal fatigue or adrenal insufficiency is where your adrenal glands appear to not be working properly.  It may be that the gland is lacking vital nutrients.  It may be that it is not receiving the correct messages from your pituitary gland.  The pituitary is the master gland in your brain that tells the others what to do. Together with the hypothalamus, it regulates all of your organs.

What are the adrenal glands?

You have never heard of the adrenal glands you say?  Well, you’re not alone. 90% of the patients that I see with adrenal fatigue have never heard of them either. Why is that?  Because your adrenal glands are one of the most overworked yet also overlooked glands in your body. They are equally important as the other endocrine glands, like your thyroid, but they are largely ignored.

Your adrenal glands sit on top of your kidneys.  They perform a variety of functions, mainly those that relate to stress.  The adrenal glands secrete a variety of hormones that regulate:

  1. Your blood pressure
  2. Cardiovascular functions such as your heart rate
  3. Immune response and inflammation
  4. Sex hormones
  5. Your blood sugar
  6. The part of your nervous system that prepares you to fight or run when you are in danger.  Your “fight or flight” response.
  7. The part of your nervous system that helps you relax, rest and digest your food

What are the symptoms of adrenal fatigue or HPA axis dysfunction?

The symptoms of adrenal fatigue include:

  1. Tiredness, despite getting enough sleep
  2. Insomnia or sleep difficulties, particularly waking throughout the night and having difficulty going back to sleep
  3. Hypoglycemia (drops in your blood sugar) if you don’t eat regularly
  4. Feeling weak, shaky, irritable or lightheaded if you don’t eat regularly
  5. Hormonal imbalance or infertility
  6. Anxiety or inability to cope with stress
  7. Poor digestion or irritable bowel syndrome
  8. Allergies, asthma, eczema
  9. Inflammatory or auto-immune conditions
  10. Mood disorders including depression and bipolar disorder

What are adrenal gland tests?

Tests for adrenal gland insufficiency include:

DHEAs

DHEAs is a weak male-type hormone or androgen that your adrenal glands produce. It is a building block for testosterone and in turn, estrogen.  It also helps with energy and libido. DHEAs acts to moderate estrogen. A blood test measures DHEAs.

Testosterone

Testosterone is a stronger male hormone that your adrenal glands help to produce.  It helps with energy, drive, motivation and libido.  Testosterone is also a building block for estrogen.  A blood test measures testosterone.

Cortisol Test

This blood test is usually drawn in the morning around 8-9 a.m. and in the evening around 6-8 p.m.   Or, you may collect a saliva sample for cortisol at 4 points throughout the day.  Cortisol is a stress hormone.  High cortisol causes weight gain.  But, you need enough cortisol for normal conversion of fat, protein and starch to energy.  It also helps with normal blood pressure.

Aldosterone

Aldosterone is a hormone that helps to manage salt and water balance.  It regulates your blood pressure.  A blood test measures your aldosterone level.

ACTH

Your pituitary releases Adrenocorticotrophic hormone (ACTH).  It is a hormone that stimulates your adrenal glands.  A blood test measures your ACTH level.

Natural treatment for adrenal gland problems

Not surprisingly every culture has their own herbs for the adrenal glands.  These are known as adaptogens.  They are herbs that help your body adapt to and deal with stress more easily. Well-known adaptogens include ginseng, Rhodiola, Ashwagandha, Schisandra, and skullcap. In addition to helping support your adrenals with adaptogens, I always recommend replenishing the nutrients that are most important for normal adrenal gland function.   For healthy adrenal function, you need vitamin C, vitamin B5, vitamin B6, zinc and magnesium.

What are the benefits of natural treatment for your adrenal fatigue?

How can supporting your adrenal glands help you?  Because these small but mighty glands are involved in so many body functions, helping them can help you with:

  1. Better energy
  2. Better ability to cope with stress
  3. Less anxiety and depression
  4. Better blood pressure
  5. More stable blood sugar
  6. Reduced inflammation
  7. Better hormone balance
  8. Improved digestion
  9. Better mood

Adrenal Gland and HPA Axis Research

Bipolar disorder is associated with dysfunction of HPA axis activity. Targeting HPA axis dysfunctions might be a novel strategy to improve the outcomes of bipolar disorder.

Depression, anorexia nervosa and obstructive sleep apnoea, are associated with increased cortisol exposure. Higher nighttime cortisol exposure is observed in patients with Cushing’s syndrome.  High night cortisol is associated with insulin resistance and increased cardiovascular risk and mortality. A decrease in cortisol rhythm amplitude is seen in adrenal insufficiency, and despite replacement, patients have an impaired quality of life and increased mortality.
