The facts (very simplistic)
The thyroid is one of the family of glands (called the endocrine
system) that controls hormone production.
In descending order (from the top of the head) they are the pineal
gland, the hypothalamus, the pituitary (all within the brain), the thyroid (in the neck), the adrenals and pancreas (just below the stomach) and the ovaries and testes.
The main function of the thyroid gland in this system is to regulate the release
of energy within the cells - so too much of the hormone will cause an excess
of energy while too little
will cause a dearth.
Thyroid hormones
There are, in fact, four thyroid hormones. The first is T4 (thyroxine) which everyone has heard of. However, T4 is really only a way of
storing potential energy until it is needed.
To produce energy it needs to be converted, with the help of enzymes, into T3,
the hormone which actually gets into the cells and produces energy.
If the thyroid cannot produce sufficient T3 to supply the body with energy then
no function, physical or mental, will be able to operate at full efficiency.
A situation in
which many M.E. sufferers find themselves.
The thyroid may be unable to function properly for many (and much disputed) reasons
including genetic failure, autoimmune disease, trauma, glandular fever, micro-malnutrition
and the impact of environmental
toxins such as fluoride.
Diagnosis
Before the development of the TSH blood test diagnoses were based on family history,
observations of symptoms (always tricky as similar symptoms can be caused by
a range of conditions) and the measurement of body temperature - the basal body
test.
The main blood test is that of thyroid stimulating hormone (TSH) - the hormone
released by the pituitary which instructs the thyroid to make more T4 to be converted
into energy
giving T3. Normal levels are deemed to run from 0.15 micro units per millilitre up to a
maximum of 6 micro units per millilitre. The more production-stimulating TSH
is found in the blood, the less well the thyroid is deemed to be functioning. But at what point between 0.15 and 6 micro
units an individual’s thyroid is failing to respond is hotly debated.
It is also possible to measure the amount of T4 (thyroxine) and T3 in the blood.
Conventional endocrinologists maintain that these measurements taken together
are sufficiently sensitive to detect an underactive thyroid.
However, a minority of specialists in both the UK and US maintain that measuring the amount of TSH, T4 or T3 circulating in the blood
does not tell you anything. What you need to know is how much is getting into
and being utilised in the cells.
They recommend different tests (only available in private laboratories) which
test urine or saliva, from which they can deduce the amount of T3 and T4 which
has actually been used over a 24-hour period. This may produce very different
results from standard blood tests.
Dr Durrant Peatfield
One of the leading proponents of this view is Dr Barry Durrant Peatfield;
the second edition of his original book, The Great Thyroid Scandal is now available - see Your Thyroid and How To keep It Healthy.
Dr Durrant Peatfield has little time for the blood tests, which he sees as being
not just useless but actively harmful in that they fail to recognise, and therefore
enable to be treated, quite serious hypo-thyroidism.
Dr Peatfield also questions the validity of treatment that consists purely in
supplementing the amount of T4 with extra thyroxine. For all kinds of reason
(explained in detail in the book) he suggests that supplemented T4 may not be
converted or properly utilised by the thyroid so be of little use.
Dr Peatfield’s treatment
His treatment suggestions include the avoidance of environmental toxins (which
may have harmed the thyroid in the first place), nutritional and adrenal support
and a carefully adjusted diet.
His other treatment of choice - and one which brought him into direct conflict
with the medical establishment - is natural dessicated pig’s thyroid. No
longer available in the UK (but still in the US) this was the main treatment
available from the discovery of thyroid failure in the late 19th century until
the development of synthetic thyroxine in the 1980s - and Dr Peatfield maintains
that it is better tolerated, better absorbed and more effective than the synthetic
thyroxine.
If you have any doubt about the health and function of your thyroid
it is worth going to your GP. As you will see from our reader’s
contributions, some do treat hypothyroidism successfully. However,
if you do not get much satisfaction then you may wish to do some investigation of your own.
Whether or not you fully accept all Dr Durrant Peatfield's theses, his book is
an excellent and accessible introduction to the subject for lay people.
There
are also a plethora of websites offering support for both sides. Sue Boniface
suggests the ones that she has found most helpful on the next page.
Sarah Early
suggests www.thyroiduk.org, ardent supporters of Dr Durrant Peatfield.
The more conventional view is represented by www.british-thyroid-association.org ‘a non-profit making learned society of professional
clinical specialist doctors and scientists in the United Kingdom who manage patients
with thyroid disease and/or are researching into the thyroid and its diseases
in humans’.
