They are so poorly trained in dealing with patients who have problems with their thyroid gland.
One of our doctors who was trained in the 50's was always trying to get the Endocrinologists to take more notice of clinical symptoms (they know none) but Dr S knew them all as did all doctors since 1892 when the very first thyroid hormone replacement was developed.
Dr Skinner was a Virologist but was brought into Thyroid by chance because about ten years after the blood tests and levothyroxine was introduced and untrue allegations being made about NDT being inconsistent, patients remained undiagnosed due to the TSH or weren't improving on levo
He was sent patients who had mysterious symptoms but he knew that most were hypothyroid and prescribed. He tried his utmost to infom the Endocrinology they were wrong in how they were diagnosing/treating patients but they ignored him. So, we had new diseases, fibro, ME and CFS.
So, today - the modern world - we have gone backwards in diagnosing/treating (usually too low a dose). The endocrinology stopped prescribing NDT - they fell for the promotion that levo was perfect - but didn't care so stopped NDT and now T3 which has left many in the lurch and desperate. This is an excerpt from one of our Advisers (deceased) who was also against the 'modern' method:
Safely Getting Well with Thyroid Hormone
ONE OF THE WORST DISASTERS in the history of medicine is the
endocrinology specialty’s modern guidelines for diagnosing and
treating patients whose bodies are under-regulated by thyroid
hormone. These guidelines and the beliefs they’re based on have
caused a worldwide public health crisis. It involves the chronic ill-
ness of scores of millions of people and the premature deaths of
incalculable numbers more. Each year, billions of dollars are spent
for drugs intended to control patients’ chronic symptoms; the drugs
are largely ineffective and often induce adverse effects in the
patients. Researchers who fail to recognize that the cause of the
patients’ symptoms is under-regulation by thyroid hormone do
studies looking for other causes. Since they are blinded to the real
culprit, their fruitless efforts squander billions of research dollars
