Doctors are not adequately educated in thyroid problems. Why? Because Big Pharma has a huge influence on the training of doctors and it is not in their interests that ANYBODY knows about thyroid! They are making a fortune out of us with all the add-on drugs that they sell to us : slimming aids, blood pressure meds, heart meds, statins, etc etc etc. If we were treated properly and got well, we wouldn't need all that! Think of the money they would lose! So, they try to keep us all in the dark about how to diagnose and treat thyroid.
This all started when they discovered how to make synthetic hormones and set about convincing everyone that synthetic was better than the usual NDT that had been used up until then. It wasn't. And patients started complaining about continuing symptoms. So... they developed the TSH test to prove that it worked (usually, you didn't have to take a very high dose of synthetic T4 to make the TSH drop) and convinced everyone that this was the gold standard test. And the rest is history!
Big Pharma is thoroughly immoral and doesn't care about people suffering. They don't create cures, they create customers! (I pinched that one from Facebook. lol But it's true!) And we thyroid sufferers are their number one customers. So, doctor training is not going to improve until Big Pharma has been toppled from its pedistal. Vive la revolution!
OK, enough of the marxist propaganda. lol But that, dear readers, is the reason why.
