... it's no wonder millions are suffering! I just found this and I am FURIOUS!

QUESTION 3:
I have been feeling very fatigued for many years. I also complain of constipation, lethargy, inability to concentrate and weight gain. I have seen several doctors including an endocrinologist; they have tested my thyroid with blood tests on many occasions. The tests always come back completely normal. Yet, I have been reading that these tests are not accurate and that measurements of body temperatures are more accurate. Moreover, I understand that I should be taking thyroid medication for these symptoms despite normal thyroid function tests.

ANSWER:
Actually the routine blood tests for thyroid function are extremely accurate and precise. Moreover, the blood tests for thyroid stimulating hormone (TSH) (which is the pituitary hormone that stimulates the thyroid even more when it is failing) is extremely accurate. It is the first test to rise when thyroid function is at all low. Indeed, it will go up even before the thyroid hormone levels are detectably lower. This is a category termed "compensated" hypothyroidism. In that state, the thyroid hormone levels are still normal, the patient still feels normal but the TSH is already an indicator that the thyroid gland itself is in trouble. In your case, with a normal TSH, hypothyroidism is completely ruled out. . It is important to remember that many other conditions can mimic hypothyroidism, most particularly chronic anxiety, depression and stress. Some psychiatrists use T3 (Cytomel, triiodothyronine) but usually not thyroxine, with antidepressants. How useful this combination is, remains to be proven. It is true, however, that such people who do not have thyroid disease can "benefit" from taking thyroid medication. The reason they are benefiting is that the thyroid medication is a "placebo". The drug itself has no intrinsic benefit to them, but if people think it is going to help them, then it does. It is like fooling yourself by taking a pill that looks identical but is completely inert. If we convince ourselves that there is some good in it, then we feel much better. Sometimes this placebo effect is truly remarkable and long lasting. More often, however, it lasts for only a short time and disappears.

It goes on but I'm so angry I can't even read any more.  A PLACEBO?

This is supposed to be an organization that supports people with thyroid disorders.
