Subclinical hypothyroidism is not only
commonly ignored, it is also grossly under diagnosed. It is easy to dismiss tiredness, feeling sick and fat to our
modern lifestyle of having too much to do and too little time. In turn, this affects sleep, mood and can
cause anxiety.
There are many reasons why subclinical
hypothyroidism is under diagnosed. The
symptoms are common with many other causes – tiredness, weight gain, anxiety,
dry skin and hair, cold hands and feet, poor memory, low sex drive,
infertility, hoarse voice, etc.
The measure of TSH (Thyroid Stimulating
Hormone) is very commonly used by doctors to measure the “normality” of thyroid
function. Unfortunately, through
running functional testing for thyroid profile for many of our clients in clinic has
revealed that very often, a patient’s TSH is normal but the free T3 is not
normal or low. The free T3 is
the active thyroid hormone and if that is low, any or a combination of the
above symptoms can show.
What can you do to make sure you have the
correct diagnosis?
If your symptoms have been persistent, you
need to order the right tests.
- You need to know your TSH, Free T4, Free T3, Reverse T3, Thyroid Peroxidase, Antithyroglobulin, TSH receptor antibodies.
- Vitamin D status
It is also important to make sure that you
have adequate amount of trace minerals iodine, selenium and zinc to allow
conversion of thyroid hormones to function adequately.
If you have high exposure to heavy metals,
which can show up in mercury dental amalgams, pesticides, exhaust fumes,
cigarette smoke (both active and passive smokers) you will “crowd out” your
important thyroid nutrients. Removing
these sources of heavy metals and having adequate minerals is the first step to
help chaperone your thyroid nutrients into your cells.
