Hashimoto's??

[alexandrakate]

This past Friday, I was seen by my endocrinologist who said I probably had Hashimoto's due to my TSH slowly increasing and FT4 slowly decreasing over the past 3 years.  My last set of bloodwork was done in April that showed TSH of 4.33 and FT4 of 0.86. He then ran another set of bloodwork at our appointment Friday which showed that my TSH is now 1.50 and my FT4 was now 1.15. I have never taken any medication and my  symptoms have not changed over the past 3 years and he is now not prescribing me any medication or taking any further action at this point. Is this normal with Hashi's or am I dealing with something else completely. Any help would be appreciated!

Those symptoms do sound like hypothyroidism and symptoms are the most important indicator; however, additional tests are required.  You can get some good info from this link.  I suggest reading at least the first two pages and also note the tests suggested in no. 6 on page 2.  You can also share the paper with your doctor to try and get treated clinically by testing and adjusting Free T4 and Free T3 as needed to relieve symptoms, without being influenced by resultant TSH levels.

There is no way of being sure from just those test results.  What, if any, symptoms do you have?  Also, if the doctor wants to be sure why doesn't he just test for the antibodies of Hashi's?  Two tests may be required:  Thyroid Peroxidase antibodies (TPO ab) for sure, and Thyroglobulin antibodies (TG ab) if TPO ab test is negative.

My main symptoms have been brain fog, fatigue, constipation, and dry skin. He said the antibody test wasn't necessarily needed. However, I will ask to see if I can get tested for the antibodies. This is all new to me. Wasn't sure what I was dealing with.
