Last week I conducted an Adrenal Stress Index Test (ASI) which involved filling four little test tubes with saliva at specific times throughout the day (8am, noon, 4pm, and midnight). This is a surprisingly difficult thing to do as you need a good amount of bubble-free saliva in each sample. Your mouth also has to be clean so as not to contaminate the sample with food particles!
The ASI measures levels of the adrenal hormones cortisol and DHEA whose levels naturally vary slightly throughout the day. These hormones help us deal with stress and provide energy and a sense of well-being. When levels aren't optimal we feel drained and fatigued and other functions such as blood sugar control and immune system function suffer.
Some of the symptoms associated with abnormal levels of adrenal hormones include:
- Fatigue
- Feeling Drained
- Hypoglycaemia/Blood Sugar Imbalance
- Dizziness Upon Standing
- Insomnia
- Not Feeling Rested on Waking
- Poor Stress Tolerance
- Depression
- Poor Exercise Tolerance
- Recurrent Infections
- Allergies
- Chemical Sensitivies
- Lack of Mental Alertness
These symptoms tend to occur primarily when cortisol and/or DHEA are too low but the same symptoms may result from an excess.
After completing my ASI saliva samples last week I had mailed them directly to the lab and got the results back a couple of days ago. First off I'd like to show you a sample cortisol profile which shows healthy cortisol production throughout the day:
There are two important factors to consider with the ASI results:
-
The levels of hormones produced
-
The rhythm of production
This examples shows that the cortisol levels are in the middle of the normal range all the way through the day. They also show the correct rhythm. Most cortisol is produced in the morning when we need a boost to get us out of bed and ready for the day's activities. The levels then drop off but remain sufficient to sustain daily activity before dropping off to near zero at midnight to allow for healthy deep sleep (stages 3 and 4).
Now my cortisol results for comparison:

As you can see, although my cortisol levels are within the reference range throughout the day (just!), the graph looks nothing like the healthy example. Instead of cortisol levels being highest in the morning they are near the bottom of the normal range, increasing by noon, and then dropping off again to the borderline of normal by 4pm. Significantly, my cortisol production rather than dropping steadily during the evening only tails off very slightly meaning that by midnight my levels are at the very top end of normal.
Now for the interpretation:
These results fit very well with my symptoms throughout the day. I find it very hard to wake up and get moving in the morning (low cortisol), generally waking around 9am and not getting out of bed until 10am. I then find that I am able to be most productive between 10am and 2pm. This is when I like to get significant work on The Environmental Illness Resource website completed. After this I notice a significant drop in energy and motivation and feel lethargic which is reflected in my cortisol production with the low point at 4pm. At night I feel exhausted and tired but am unable to relax. I also find it hard to get myself off to bed so despite being tired I end up getting to bed later than I should i.e. midnight or later. This is all to be expected when cortisol production is higher than it should be.
Now my DHEA results:
note: DHEA-S is the sulphated form of DHEA and is often described as the storage form of the hormone. It is found in much higher concentrations in the blood than DHEA itself.
DHEA-S levels should follow a similar pattern to the example of a normal cortisol result shown above. As you can see my DHEA-S levels follow the same erratic pattern as my cortisol levels. In this case however the unusally timed high points are even more pronounced and go significantly above the normal reference range. The role of DHEA-S (and DHEA) is less well understood than that of cortisol but it is though to provide a counterbalance to the actions of cortisol. The high levels at night in theory then should help me to relax and get a good night's sleep.....unfortunately this is not the case.
Strangely I have found in the past that DHEA supplements have provided me with enormous benefit in a great number of symptoms (e.g. energy, sleep quality, stress tolerance, well-being, blood sugar balance). Confusing when it now seems my levels of DHEA-S are only slightly during a few hours in the afternoon.
One explanation could be a licorice supplement I took for a while a year ago which initially provided me with more energy and motivation and allowed me to wake earlier and get more done during the day. However the benefits soon wore off and I now feel more stressed than ever. Licorice is known to boost the action of cortisol by slowing its breakdown and possibly making the body's cells more sensitive to it. It may also effect other hormones such as DHEA.
What is clear from my ASI test results is that my circadian rhythm (body clock) is completely out of sync with what it should be. I have too much cortisol at night which affects the quality of my sleep and not enough in the morning to get me going. In effect this is a double whammy making my body exhausted and totally unprepared for the day ahead. As a chronic fatigue syndrome (ME/CFS) sufferer this is not so unusual as the illness is thought to have a major component of endocrine dysfunction so hormone levels can be all over the place.
From my current knowledge and some reading I have done since receiving the results of my ASI it seems in terms of treatment I need to make sure I get to sleep much earlier and improve the quality of that sleep through whatever means possible. Boosting cortisol and DHEA levels in the morning (without over doing it)would be helpful too. Perhaps taking DHEA supplements in the morning in the past normalised the rhythm of my adrenal hormone production and brought about the improvement in symptoms........but this is purely conjecture.
I have not yet had any feedback on the results from a medical professional. The test was ordered for me by Dr. Sarah Myhill and I am awaiting her opinion on the results. I will update here when I receive it....

I was looking at how adrenal function is affected by mercury poisoning when I came across a set of charts showing ASI test results during chronic fatigue progression. This one stood out:

Four years ago I used to spend long hours up at night on the computer. I used to average 4-5 hours of sleep and then a compensatory nap in the evening after school. Being on top of my grade, I had a lot going for me, but for some reason I started to feel dumber, and fast. I went through a lot of emotional stress at that point as well and now years later, my symptoms just get worse, with new ones coming and going. There is no doubt that something is seriously wrong with my body (hypoglycemia and blood sugar imbalance being key to my problems as well as 4 AM insomnia), and life style changes just aren't enough anymore to fix things. I know exactly how you are feeling with all your mentioned symptoms and I am just looking for an answer. Thanks to your brilliant post, I have more lead now on my investigation.
Life really is a long journey of learning. Maybe fixing my adrenal issues can make me an even healthier person than I would have otherwise been had none of this happened. I live in Toronto, so my first step will be to seek out a medical professional who can assist me in running an ASI test.
I hope someday I can end this Half Life. God Bless us All.

What are the accepted "normal" levels for cortisol at differnt times of day? from the looks of your sample graph it has normal in the 20's or 30's, but my lab test (saliva cortisol) gave me the "normal" as roughly never going above 6.3 in the early morning. This is a huge difference since my results were always on the high end of normal, and could either be interpreted as normal in the morning (5.7) or very low, depending which set of standards I go by. Thanks for any comments/insights. it's tough getting good info on this issue.

About a couple of my symptoms: Sometimes I wake up have no trouble getting going, though I feel strangely hyper/wired. Could this still fit in to having very low cortisol? This week has been different though, and I have actually been quite groggy and tiredfor the first hour or two of the morning. But it's been confusing me, the wired feeling in the morning. I should add that I often wake up between 4-6, and then have terrible sleep, going in and out, having strange, fever-like dreams. Then I feel tired when I get up.
Sorry, don't mean to barrage you with questions, but it's so nice to talk to other people who are also figuring out similar issues as mine.
Thanks

I can't imagine how you found Lab 21! They don't come up when you search in Google for Adrenal/Cortisol test, as I have multiple times over the last year.
They are friendly when you call them. And the test price is lower than I expected.
Two links I found that might be of interest to you and anyone reading this site because of:
a. Insomnia (of the kind where you get to sleep easily but sleep lightly and wake up at night) OR
b. Chronic Fatigue
http://www.health-spy.com/adrenal.html
http://www.health-spy.com/insomnia.html
It's taken 3 years of trial and error to me understand that my insomnia is likely linked to a stress/sleep hormonal imbalance.
That site shows understanding of the problem that's better than anywhere else I've seen. He (or she) writes about Insomnia/CFS in terms of 2 hormonal balances:
Daytime Cortisol / Night time Cortisol
Daytime Melatonin / Night time Melatonin
I won't go into too much detail, but it's there I learned that low day time Cortisol is associated with higher secretions at night with resultant waking.

If you check out this link I mentioned above, the page gives multiple alternative supplements that stimulate Cortisol production.
Go here: http://www.health-spy.com/adrenal.html and go to the section "Treatment of Hormonal and Neurotransmitter Deficiency and Imbalance:"
He lists about 12 adaptogens/stimulants for stimulating Cortisol and also talks about 5 HTP for increasing secretion of Melatonin. 5 HTP has helped me improve my sleep. That's how I knew I probably had hormone related problems. Actually that's not when I first suspected: I'd been taking about 3.5g of Ornithine per night and it helped me sleep better when nothing else did. I couldn't figure out why, but finally discovered that it increases secretion of Growth Hormone.
That's what gave me this new scent of an underlying cause: an imbalance in hormones. We'll see where it leads...

I have a somewhat "off topic" question: Have you tried betaine HCL for ensuring proper digestion? I'm asking because I'm realizing (for the umpteenth time) that I probably have low stomach acid. And it seems likely that it's been that way for years. I came across an article that listed "hormonal imbalances" as an effect of prolonged hypochlorydia. To which I thought, "Duh! of course. Why haven't I taken care of this yet?" And then I remember: About a year ago a nutritionist/chiro I saw had me try the stuff, and it seemed to have the opposite effects it was meant to. It caused some bloating, gas, stomachache, and a warmer than usual feeling in my stomach.
But it's really been bugging me, because lots of my symptoms point towards LOW stomach acid, yet I can't handle the stuff. I've been thinking maybe my stomach lining is too weak/sensitive right now, and if I could protect it with certain supplements, maybe I could start digesting my food more fully.
It's just funny, my focus (or obesession) of my health goes in cycles; "Oh it's my thyroid that's the problem!" or "Oh it's my adrenals that are the problem!" or "Oh it's the way I react tp stress that's the problem!" but it ALWAYS comes back full circle to, "Oh yeah, if I could just digest all this good food I'm eating, I would start feeling better."
Any thoughts/past experiences? Right now I'm just convinced that this could be a huge piece of the puzzle. Just makes sense. My health struggles "started" about 4 years ago, and I recall a bout of chronic heartburn/mild reflux shortly beforehand.
Thanks

Just in response to your post.
I've done very well with iherb.com as a supplier to the UK. Great prices, great delivery and shipping (very reasonable shipping charge with USPS).
I was using Now Foods Ornithine 500mg up to ELEVEN tablets per night. Crazy I know. It came from a recommendation from Hulda Clark who talks about Ornithine in relation to parasites and says to take as many as you need until you sleep better. I followed this advice with no adverse effects. I took up to 11 but have been able to reduce to the dose now to 7. I did 2 parasite cleanses after which I still needed Ornithine so I knew it was nothing to do with that. Great prices for that product on iherb.com.
As you know, dose really matters and often, to get noticeable effects from food supplements we are talking BIG doses over the RDA.
Also, to clarify Dr Michael Murray ND suggests to take up to 300mg of 5-HTP. Now Foods 100mg worked for me recently, but stopped. I like to take as little as possible of stuff. I was disheartened of course. Then I increased the dose to 200mg and am now sleeping well again. If you search 5 htp in google UK you'll see Murray's site 5htp.com. I closely followed his recommendations to ALSO accompany the 5htp with Magnesium, and Vitamin B12 and B6, in high dosage.
I'm just explaining the complications of either Ornithine or 5HTP to anyone reading.
NDs - Naturopathic doctor's - lead the way in this new kind of modern natural medicine and the new illnesses. But where can I find find one to help me? Some do publish their advice freely, in simple English.
You might try iherb for melatonin.
Good luck and courage,
Luke
