Most doctors only check thyroid levels with a TSH test. This test does not detect Hashimotos. A more accurate method is testing for antibodies. Here's a link to research regarding the connection between PCOS and Hashis: http://www.drhagmeyer.com/hashimotos-thyroid-disease/women-pcos-often-have-hidden-hashimotos-autoimmune-thyroiditis/
There are new studies that show that even if you do not have Cushings, you may have adrenal fatigue. Adrenal fatigue is very common with autoimmune disorders and especially with Hashis.
I am just beginning my research and trying different things. I was hoping that I would lose weight and everything would get magically better. I also thought that if it didn't the doctors would stop blaming my weight for why I felt like crap.
The first thing I have been doing is trying to get my Vit D levels to an optimal level (around 80). I've been on 50,000IU a week and that raised it to 50. It's in the normal range, but for Hashis they recommend 80 or above.
The second thing I am doing is adding in T3 in addition to the Synthroid I am taking. I'm trying to get my Free T3 into the upper third range of normal. Hopefully it will be there next time I get bloodwork.
The third thing I'm doing is getting my Ferritin levels to an optimal level for Hashis (90-110).
Once I get these 3 things straightened out I am going on an AIP (autoimmune protocol) diet. It's gluten and soy free plus an elimination diet for eggs, dairy, nuts, nightshades, and seeds).
I'm doing all of this with the assistance of my acupuncturist. His wife was debilitated by Hashis and through his research and the assistance of the book "Stop the Thyroid Madness" he helped her feel better. He told me that my answer doesn't lie with Eastern medicine (acupuncture), it is in Western medicine and functional medicine. I haven't been able to find a functional medicine practitioner in my area, but if I'm not better in six months I'm going to go see one that's a few hours from where I live.
