Re: Please take a look! Out of answers...thyroid???

You're on to something. Your family history seems to have cursed you.

Even though your TSH is maddeningly "normal", your free T4 is very low (according to the typical lab range of .8 - 1.8. Please let us know if your lab's range is different, and always include those ranges when posting your results). Almost no one feels well when T4 is that low.

Also, your free T3 needs to be tested. Since you have such a strong family history, you need antibody testing for TPO and Tg antibodies. The familial form of hypoT is usually caused by an autoimmune disease know as Hashimoto's thyroiditis, and the presence of antibodies would confirm that. Antibodies also suppress TSH, which could account for your "normal" TSH in the face of low free T4. Some doctors will begin treatment if antibodies and symptoms are present, even if TSH is normal and the free Ts are low-normal.

The main thing you should know is just how many MDs don't recognize and won't treat the cases of hypoT that don't fit the textbook; but if you seek enough opinions, such obvious cases as yours will eventually be caught.


Don't give up on this! Take it to as many MDs as you have to to win a diagnosis. I was also told my levels were "normal", but I knew they weren't and didn't give up. I got my Hashi's diagnosis from an endo. A family practice MD is now treating it.
