Low TSH, T3 and T$

[juliettequaedvlieg]

I have had my thyroid removed app. 2 years ago. It took me some time to find the correct drugs but I was doing fine taking 275 MGR Cytomel. on the 13th I had a seizure while I was on business in NY. I remember very little of what happened. I am now back in the Netherlands and nobody has an idea what is going on. All my levels are low:
TSH  <0.03 mU/L
T3     6 ng/dL
Thyroxine  0.7 Ug/dL

They strange thing is that I really do not feel that bad. I mean....I have felt worse with levels that where much higher then this.

Does anybody have an idea what might be wrong when ALL your levels are low? They are now suspecting that there might be something wrong with my pituitary gland or hypothalamus. I had a CAD scan and that was ok.

Please let me know if you have an idea.
regards

hello, my doctors think that they might have measured my T3 wrong. this morning They took blood again and I will have the results tomorrow or the day after tomorrow. They have also done a lung xray. They are thinking I mght have a tumor on my pituitary glend. If I have a tumor there it migt be a metastase from breastcancer or lungcancer. A quick scan of my lung xray showed that all was ok, but I am still waiting for final results. I wil have MRI's on thursday together with an EEG (that measures brain activity). The problem in Holland are that there are waitinglists for basically everything ! I can consider myself to be quite lucky because I have some friends that are surgeons and that are putting me ahead of all waiting lists. They are still looking for a link between my thyroid and the seizure, but I am thinking more around the line of 2 seperate events. I have been flying a lot recently and maybe mty thyroid levels where low and then a big jetlag on top of it caused my seisure. They are also testing for Antibodies to rule out Hashimotos encyphalitis. I will keep you posted.

.A few rambling thoughts from what I have read:

Are you not taking any T4 supplement with Cytomel?

When  TSH is low cytomel dose might be too high.

Cytomel may decrease T4 and has a short half life, so if labs are done before cytomel dose,  it will make the T3 look low as well.

It is suggested to do another test 6 weeks after the above test to confirm, thereabouts, just in case of error.

I never seen a T-3 that low - did you forget a zero?  ;)

If next test  levels are low, but depending how they relate to each other, could mean adrenal fatigue or other problems such as allergies, hormonal imbalance or yeast.

If pituitary function, T-4 will be much lower than the T-3.  Your T-3 is much lower than your T-4.

These are my best guestamations (and not a diagnoses).

Good Luck and if you get a diagnoses let me know.

My reference values are
Result Name                      Result     Abnl   Normal Range    
Units
TSH                              <0.03      l      0.38-5.50      
mU/L
    
T3                                   6           l        60-181          
ng/dL
  
Thyroxine                        0.7        l      5.7-11.4        
ug/dL

They have tested FT4 and FT3 as well but I do not have the values at hand, but they are very low as well.

What are your Labs reference range.  If you are estrogen by whatever means, the FTs should be done ( Free 4 and Free 3).
