The 2013 guidelines issued by the American Association of Clinical Endocrinologists and the American Thyroid Association reiterated their long standing opinion that only a single hormone, T4 (Synthroid, levothyroxine) is advised for treatment of hypothyroidism. These key organizations
Mainstream endocrinologists seem to be moving grudgingly toward acceptance of combination T4 plus T3 therapy for hypothyroidism. A great example of the mixed feelings harbored by endocrinologists in this regard is the title of a recent editorial, “ Combo (treatment) a Last Resort for Hypothyroidism” . Although the author, Dr. Bruce Jancin of the University of Colorado, recognized the value of combination T4 plus T3 therapy, he did so with the least possible enthusiasm. In his article the doctor acknowledged the weakness of scientific studies showing negative results with combination therapy and pointed out the findings of the Watts Study which provides a genetic rationale for why some people need to have T3 added to T4 to return to proper thyroid hormone balance.

I thought Richards comments about the battle he faces getting treatment for hypothyroidism after having his thyroid removed for cancer, would be of interest to many readers at metabolism.com.
I recently ordered Thyroid-S on Amazon.com and after all the research and apparently good results I have found online, I think I made the right choice. I had my thyroid removed because of cancer in 2005, took Cytomel at first, felt great, told to stop cytomel and start Levothyroxine, felt horrible. Two months out(125mcg) TSH was 43.0, increased dose to 137mcg wait another 2 months, TSH was 31.0 Finally told to take 200mcg and TSH started to come down. It took about 6 months to get my TSH where they wanted it and for the side effects I was given all types of medications. Continue reading
A long time member of metabolism.com, Eric Pritchard, has been a determined critic of “T4 only” treatment of hypothyroidism. In his latest comment Eric shows that scientists were aware of the inadequacy of “T4 only” treatment since 1947! I wanted to give everyone a chance to read his comment so I am posting to the main blog. Thanks again for your insight Eric.

Endocrinologists have a hard time with the symptoms of hypothyroidism in the same sort of way that New York City folks believing that there is anything worthwhile west of the Hudson River. However, there are very relevant functions to the thyroid hormone effectiveness that exist beyond the boundaries of the classical endocrine system. This potential was given initial credence by Drs. Kirk and Kvroning in 1947 when they published a note saying that not all patients’ symptoms were managed by thyroxine (T4). This was collaborated in 1954 by Dr. Means. Drs. Gross and Pitt-Rivers discovered triiodothyronine (T3) and found it far more active than T4, which is now called a pro-hormone. The concept of euthyroid (your thyroid is OK) hypometabolism (but you are dragging anyway) was demonstrated by Dr. Goldberg in 1960. Drs. Refetoff and Braverman, circa 1970, discovered the connections between the thyroid gland and symptom producing cells, namely the cellular reception of hormones and the conversion of T4 to T3 outside of the endocrine system, which produces 80% of the body’s requirement for the active hormone, T3.
Another issue that is dismissed is the necessity of supporting chemistry to function properly. For example, every thyroid hormone replacement counter-indicates is use if the adrenals are insufficient.
So there is far more going on than endocrinology is willing to promote. That is why there are 1.7 million patients suffering in spite of T4 therapy. That is why there are still more patients suffering from false negative diagnoses for the symptoms of hypothyroidism.
