Low FT3 and FT4 - normal TSH

[JoStafford]

Hello,

Can anyone please help me with my problem?  I have had an underactive thyroid for 3 years and have felt terrible nearly every day.  

My last blood test my results in Sept 09 were:

TSH - 1.5 (1-5.5)
FT4 - 10.1 (9.9-25)
FT3 - 4.4 (3.9-6.5)

As you can see, my FT3 and FT4 levels are at the low end whereby my TSH is within normal limits.  I guess this means I have have conversion problems.  I take 75mg of T4 and 5mg of T3.   My Endo suggested I increase the T4 to 100/75 on alternating days.  This gave me huge anxiety attacks and insomnia so I reduced it back down to 75mg.  

I am due a blood test in January.  The test is for TSH, FT4, FT3, Vit D (I was vit D deficient), Calcium and RT3.   Does anyone know what other tests I can ask for?  My DHEA was normal in my last test.

I've read a bit about conversion problems and know it could be due to adrenal, liver and digestive enzyme deficiencies.   Are there any blood tests I can do to find out whether these are the problem?

Thanks so much for any advice here.

Jo

Ok.

"more informative and helpful answers"  - yes.

With this site being world wide, peoples  definitions and the use of  English can greatly vary as well -no way around this. Many list there general location, this helps in several ways, in communication, meds, available treatment options, and even their view point ect.

I agree with LazyMoose on this one. First off, I don't think you "hijacked" the thread.  This forum is not about who knows more or who can post the most responses, just to be posting.  I think it's much easier to work from a personal stand point, rather than a "general" one and post our own information and experience.  For instance, I have hypothyroidism/Hashimoto's -- I rarely post anything regarding hypERthyroidism/Graves -- that's not my area of experience.
