Adrenal fatigue is a condition not widely recognised by conventional medicine yet, though I believe it’s only a matter of time until it is. It just makes so much sense.
The adrenal glands, which sit atop the kidneys, are responsible for producing hormones in relation to stress etc. and the one concerned in adrenal fatigue in cortisol. Now, there are two recognised conditions in conventional medicine, in association with extreme dysfunctioning of the adrenal glands. Addison’s, which is a long term condition whereby the adrenal glands do not produce enough cortisol and Cushing’s is the opposite – where the adrenals produce often dangerously high levels of the hormone.
Adrenal fatigue is a condition well recognised within functional medicine, whereby the adrenal glands produce too much or too little cortisol, though not to the extent of Cushing’s or Addison’s, but abnormal enough that it causes symptoms and issues all the same. Symptoms are listed below.
Adrenal fatigue can include elevated, lowered or mixed levels of cortisol, without it being the full blown condition of one of those two. This condition is very real. Thousands of people report symptoms and problems, especially thyroid related, with adrenal fatigue (high, low or mixed cortisol levels).

Perhaps when you exercise, you suddenly feel light-headed, a blood sugar drop and faint? Then it’s likely you have adrenal fatigue.
The adrenal glands are part of the endocrine system, just like the thyroid. They handle many hormones that are important for a lot of bodily processes, such as handling stress. This where cortisol is produced.
According to James Wilson’s book Adrenal Fatigue, the adrenals first respond to stress by providing you with extra cortisol, but the body can only keep up with high cortisol for so long. So after this, the cortisol starts to fall, leading to low cortisol. In between this, you could have combined highs and lows. You could have high, low or combined high and low cortisol causing these symptoms. This is called adrenal fatigue. Cortisol has a variety of important functions, including: the metabolism of carbohydrates, proteins and fats, affecting blood sugar levels in your blood, helping reduce inflammation and helping you deal with stress. The latter is especially huge.
I suffer from adrenal fatigue at the moment, after being left hypothyroid for too long without treatment, and then being held to Levothyroxine when I did get treatment, which wasn’t the right medication for me. I arranged for a saliva test to be done privately (a 24 hour, 4 point saliva test). When I got the results back, they showed that my cortisol was elevated 24 hours a day, indicating adrenal fatigue and a cause for many of my ongoing symptoms; mainly fatigue.
In thyroid patients of all ages, many of them may be labeled with psychiatric issues such as mental health issues, when they are actually due to hormonal insufficiencies such as adrenal fatigue. In one study, it was concluded that by correcting the underlying hormonal imbalance, many patients’ mental health improved, with some patients having a total reversal of psychiatric symptoms.
In terms of exercising, Sara Gottfried explains in her book that a sign of adrenal issues can even include trying to exercise, only to find you crash, feeling light-headed and faint. This is due to cortisol being part of the glucocorticoid family, a substance that raises your glucose level. It’s cortisol’s job, to give you energy. When you have this reaction to exercise, it’s a sign you’ve used up your main energy supply as you’re perhaps low on cortisol and so don’t have enough ready to use.
So, adrenal fatigue could be caused by low, high or combined low and high cortisol. What’s the difference?
High cortisol – Stage One
High cortisol has very similar symptoms to low cortisol, and is usually the first stage before low cortisol, as explained above. If you can catch it while it’s like this, you may have an easier time fixing your adrenal fatigue. As mentioned above, this is what I have.
High bedtime cortisol can cause disruption of your sleep pattern, resulting in problems falling asleep, or staying asleep, so this could be a key sign!
Combined high and low cortisol – Stage Two
This stage is thought to come between high cortisol and low cortisol, when the adrenals cannot keep up with high cortisol any longer, and so it starts to drop at certain points.
Low cortisol – Stage Three
This is not the same as the disease called Addison’s, low cortisol is actually a long-term situation where, though your adrenals may still work, they are either out-of-sync or inhibited. As explained above, this happens when they first produced elevated cortisol, then combined highs and lows of cortisol, and then low cortisol.
Usually lifestyle and dietary changes also need to be made, in order to recover from adrenal fatigue. Lots of info on this can be found in James Wilson’s great book but I’d also recommend consulting a medical practitioner who does recognise adrenal fatigue, such as functional doctor, naturopath etc.
Dysfunctional adrenals can result in high amounts of T3 from your thyroid meds to build in the blood, making your free T3 results look high, but with continuing hypo symptoms, or causing hyper-like symptoms. Fixing your cortisol levels should fix this.
It is never wise to guess whether you have low or high cortisol, symptoms for both are similar. So don’t attempt to treat adrenal fatigue without first confirming if you have it and what at what stage.
Order or ask for a 24 hour saliva test, testing your cortisol levels at four key points of the day, to find out if you have adrenal fatigue. If your doctor won’t do this, you can very simply order it yourself and complete it at home. A UK test can be found here and a US test here. Most doctors will only test it with a one time urine or blood sample, which is not as accurate. Four samples taken over a 24 hour day show how your rhythm of cortisol production is working. It should be highest in the morning, tailing off throughout the day. Only four saliva samples taken in one day will tell you this accurately.
I urge you not to make any changes to your personal health regime before consulting a doctor and/or pharmacist, first.
