I was recently diagnosed, through two blood tests as having an under-active thyroid. I had none of the usual symptoms, but I was prescribed Levothyroxine 50 micrograms and told to take it for the rest of life. I guess in all likelihood the dosage will need to be increased in the future, depending on blood test results.
But I have a question. Perhaps the under-active thyroid is only a temporary imbalance – a response to some environmental or psychological factor.. And what if those factors change or end after a while? In the absence of medication I can imagine that the thyroid swings back into normal operation.
But as I AM taking medication, the thyroid hormone levels in my body are normal, are they not? So the brain does not know there is a problem. So it does not act (assuming this is possible) to adjust hormone production in the thyroid gland. So the gland stays in under-production. It has no chance of functioning normally again. And the condition becomes entrenched
The same sort of argument is applied to the wearing of glasses. The refractive error produced by the eye may be a temporary imbalance, as a result of stress, environmental factors, etc. If the glasses are prescribed, the eyes are in focus with those glasses even though they are producing a refractive error. And so the brain is fooled, it says to itself ''Everything is perfect, no need to adjust the eyes''. And so the refractive error becomes fixed, established.
I would welcome people's comments on this perspective.
