Low TSH, T3 - Synthroid & Hashimoto's

Answered on March 14, 2014

I am looking for some help deciphering my thyroid panel. I was Dxed w/ Hashimoto's 6 years ago and have been on a consistent Synthroid dose since then. My TSH used to be normal during the first 2 years on Synthroid, but it is now Low (.04) and my Free T3 is also low (58). My LH, FSH, Estrogen & Progesterone are Low resulting in amenorrhea (missed periods).

My question is - can anyone explain to me how all these numbers may be related? My doctor keeps telling me "T3 has nothing to do with it" and that I should "go see a gynecologist about my female hormones". I think it is all related, but I do not have the medical background to make the connections.

If you can shed a little light, I would really appreciate it!

Go on Facebook, and join the groups: Stop the thyroid madness TPO and Hashimotos 411. The folks on there are very knowledgable, and you'll get excellent support.

Please visit stopthethyroidmadness.com and BUY THE BOOK. It changed my life. You can putts around the site for ages, but reading the book really helps.

Free T3 has everything to do with "it"! Hashimoto's disease is progressive and you may have "swings" or "flares" where you become HYPERthyroid or more hypothyroid. You need to monitor your symptoms closely. Post diagnosis, the only test that really matters is your Free T3. That is measuring the amount of thyroid hormone available for you body to use, thus why it is so important!

Most hypothyroid folks do much better on NDT(Natural Desiccated Thyroid also known as Natural Thyroid Hormone) which is prescription drug made of dried pig thyroids. NDT contains a more natural form of T4 plus a bit of direct T3. You may need to get a new doctor that is more open to prescribing this type of drug.

At a very basic level, TSH is secreted by the pituitary gland and signals the thyroid to produce more hormones in the form of T3 and T4.

If your TSH is low, it means your body senses that it has enough T3 and doesn't need all that much. If your TSH is low, so will your T3 and T4 - this is likely due to the Synthroid and would be normal function.

(The number 3 or 4 refers to the number of iodine atoms used to make the hormone. T4 is a storage form which gets converted to the active T3 form. It's also possible that in some cases, if you go too low carb, you'll produce reverse versions of these which are useless.)
