Adrenal Fatigue or HPA Axis Dysfunction
Adrenal Fatigue – Are you a type A personality? A high achiever? SuperMom? People wonder how you can manage to do so much in a day or do so many things so well? Under lots of stress? You may be at risk of or are already experiencing signs of adrenal fatigue, also known as HPA axis dysfunction.
What are the adrenal glands?
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 the adrenal glands are one of the most overworked yet also overlooked glands in the body. They are equally important as the other endocrine glands, like the thyroid and the ovaries, but they are largely ignored.
The adrenal glands sit atop your kidneys and perform a variety of functions, mainly those that relate to stress. The adrenal glands secrete a variety of hormones that regulate:
- Your blood pressure
- Cardiovascular functions such as your heart rate
- Immune response and inflammation
- Sex hormones
- Your blood sugar
- Sympathetic nervous system – the part of the nervous system that prepares you to fight or run when you are in danger
- Parasympathetic nervous system – the part of the nervous system that helps you relax, rest, and digest your food
What are the symptoms of adrenal fatigue or HPA axis dysfunction?
- Tiredness, despite adequate sleep
- Insomnia or sleep difficulties, particularly waking throughout the night
- Hypoglycemia (drops in blood sugar) if you don’t eat regularly
- Feeling weak, shaky, irritable or lightheaded if you don’t eat regularly
- Hormonal imbalance or infertility
- Anxiety or inability to cope with stress
- Poor digestion or irritable bowel syndrome
- Allergies, asthma, eczema
- Inflammatory or auto-immune conditions
- Mood disorders including depression and bipolar disorder
What blood tests can be done for the adrenal glands?
- DHEAs – DHEAs is a building block for testosterone and in turn, estrogen, it also helps with energy and libido. It acts to moderate estrogen.
- Testosterone – Testosterone helps with energy, drive, motivation and libido and is also a building block for estrogen.
- Cortisol – This blood test is usually done in the morning around 8-9 a.m. and in the evening around 6-8 p.m., or done as salivary cortisol at 4 points throughout the day. Cortisol is a hormone secreted under stress, excess cortisol can cause weight gain, but there needs to be adequate cortisol for normal conversion of fat, protein and starch to energy and for normal blood pressure.
- Aldosterone – Aldosterone helps to manage salt and water balance and regulate your blood pressure.
- ACTH – Adrenocorticotrophic hormone (ACTH) is a hormone released by your pituitary that helps to stimulate your adrenal gland function.
Natural treatment for adrenal fatigue
Not surprisingly every culture has their own herbs for the adrenal glands, also known as adaptogens. These are herbs that help the body adapt to and deal with stress more easily. Well-known adaptogens include ginseng, rhodiola, ashwagandha, schisandra, and skullcap. In addition to helping support the adrenals with adaptogens, I always recommend replenishing the nutrients that are most important for normal adrenal gland function: vitamin C, vitamin B5, vitamin B6, zinc and magnesium.
What are the benefits of natural treatment for your adrenal fatigue?
- Better energy
- Better ability to cope with stress
- Less anxiety and depression
- Better blood pressure
- More stable blood sugar
- Reduced inflammation
- Better hormone balance
- Better digestion
- Better mood

Adrenal Gland and HPA Axis Research
Bipolar disorder is associated with dysfunction of HPA axis activity, with important pathophysiological implications. 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 cortisol rhythm phase shifts and increased cortisol exposure. Higher nocturnal cortisol exposure is observed in patients with Cushing’s syndrome and adrenal incidentalomas with autonomous cortisol secretion and 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.
