What are the risks involved in taking these hormones? As I understand it there are two possible situations. One is that corticosteroid and/or thyroid hormones are taken in a small supplemental dose that will suppress normal production and therefore have no significant continuing effect. The other is that the doses are big enough to produce a physiological effect which, unless there is pituitary, adrenal or thyroid disease, will produce a hormone excess syndrome.
I think you are missing the third situation which is, of course, the goal of any treatment with hormones. That is, the *optimal* hormone level will be replaced with exogenous hormones to provide the benefits of the hormones as nature intended while minimizing risks and side effects.
Appropriate, optimal hormone levels are mandatory for proper functioning of every system of the body. No system, including the immune system, can function efficiently (or sometimes even at all) without cortisol and thyroid hormones.
You are right that too small doses have either no effect or will make a person feel worse.
Hormone excess syndrome is not seen in physiological replacement, only in pharmacological dosing.
Note that in the first situation the person will feel 'improved' on starting cortisol, thyroid or oestorgen. All of these in different ways produce a 'lift' of a sort. That lift will disappear as soon as the gland is suppressed - maybe within a few days. But if the person stops the treatment they will feel lousy for a while.
All that means is the dose is too low and needs to be raised to optimal. It does not mean that the dose is too high. This is a common misconception typically made by those who have never actually taken hormones.
So 'improvement' on taking these hormones and 'worsening' on stopping them will happen to anybody who is down - and will have absolutely nothing to do with the hormones being useful for any disease they might have. Long term treatment will achieve nothing at all. The temporary effects will occur in people without ME. The situation is probably a bit like smoking or drinking coffee or alcohol or taking valium. Selling something that you get hooked on for reasons that have nothing to do with an illness may be OK for adults and it may cause no harm at this level but for most of these things we have laws protecting children against foolish usage. Note again that by definition at this level even if the person has ME and hormones turn out to be good for ME they will get no benefit, since gland suppression ensures that their hormone levels over time are essentially unchanged.
Comparing appropriate hormone treatment to drinking or smoking is so far off base it isn't even funny. Although, strangely enough, when you treat people with endocrine diseases with appropriate hormones, often times their urges to drink or smoke stop or are greatly lessened. Turns out nicotine and alcohol are pretty great hormonal stimulators. But of course, why do that when one can insist on a 12 step program with a recovery rate less than 5-10%? And, BONUS, then you get to blame the patient for being weak when it fails!
How does gland suppression ensure that their hormone levels over time are essentially unchanged? If the hormone level is unchanged, the dose is not high enough.
If the dosages are high enough to have a genuine effect on long term hormone levels there are serious complications to consider. For corticosteroids we have diabetes, juvenile cataract, bone loss, weight gain, skin atrophy, scarring acne, hair loss, coronary artery disease, etc etc even with doses that raise levels marginally. For thyroid hormones we have bone loss and at higher levels atrial fibrillation with cerebral embolism and stroke. Oestrogens have all sorts of effects too.
I've already addressed the myths of thyroxine supplementation causing osteoporosis. The scientific literature does not agree.
Hyperthyroidism produces fibrillation - but that means that the thyroid dose is too high, or the cortisol dose is too low, so in essence all this means is that the hormone treatment is again improperly managed. At optimal levels, these things do not happen.
Estrogens also are protective against heart disease and osteoporosis. The follow up to the WHI study showed this but to much less fanfare than the original study results because they were not nearly so fear-mongering as to provoke the attention of the media. This has resulted in women stopping BHRT for no good reason and suffering in vain.
As far as steroids, talk to any Addison's patient and read the literature - physiological doses of steroids do NOT cause the effects you list. If one is getting those side effects, the dose is pharmacological and too high. Here is the biggest side effect of too low cortisol: death by adrenal crisis. Most with ME/CFS do not have Addison's disease but low cortisol has been a consistent finding and should be treated rather than brushed off as most studies have tended to do.
Dr Hertighe appears to belong to a group of prescribers who feel that hormone deficiency can be diagnosed at normal test levels. My question would be how that diagnosis can be made. If it is on the basis that people feel a bit better when given a small dose of hormone, from what I have said above this would seem to be invalid - normal people or people feeling down for any reason may feel better for a brief period. If hormones are prescribed to a child with normal tests I think that does raise very serious legal and moral issues.
Tests are not the be all end all of medicine. I personally believe examining the patient and their symptoms is also of value, especially when there is so much that is not understood about hormones.
As far as I know, there is no "standard" level of optimal hormone levels, only antiquated ranges that encompass 95% of the population.
There is no mention of enzymes or binding proteins that might also be causing hormonal dysregulations as a factor in interpreting test results for the most part which is a huge oversight in my opinion.
Most endocrinologists don't even know how to administer the tests we do have properly and then make diagnoses based on these improperly performed tests all the time to the detriment of the patient.
Hertoghe may be over the top in terms of hormone treatment, but at least he is willing to treat the patient rather than a piece of paper. Subclinical deficiency is a real phenomenon due to the problems with the tests, not the problems with the patient.
