Thyroid problems

[anariodrigues]

Hello!
So, it's been almost a year since I found out that my TSH levels are high (5.51 and the maxium is 5.45). I've been taken 0,025mg od tyrax every day, and then I did blood tests again and the TSH levels were the same (this in December). Well, last week, I went to a new doctor and he had me tested again and, surprisely, my TSH were 2,49 and T3 and T4 were normal, but my anti TPO is 85 (value of reference <40).
I was surpriesed to see that my TSH is fine, because I'm felling tired everyday and some days I can't sleep well. I used to be an athlete but I eventually gave up because I coundn't run and study anymore, because of my physical and mental fatigue.
What should I do?

Your TPO antibodies test indicates that you have the most common cause for hypothyroidism, which is Hashimoto's Thyroiditis.  With Hashi's the autoimmune system mistakenly thinks the thyroid gland is foreign to the body and produces antibodies to attack and eventually destroy the gland.  As this progresses your thyroid hormone levels will diminish and need to be replaced with thyroid meds.  

You are most likely in the early stages of Hashi's, where you have begun noticing symptoms, but your test results are still within the so-called "normal" ranges, so many doctor's do not prescribe meds until test results exceed their range and symptoms become very bad.  Other doctors will start earlier in order to minimize symptoms.  You can read about that approach in this link.

So I suggest that you should ask your doctor to start you on thyroid meds.  Also, the next opportunity, you should ask to be tested for Free T3 and Free T4, rather than Total T3 and T4.  Free T3 is the most important because it largely regulates metabolism and many other body functions.  Scientific studies have also shown that Free T3 correlated best with hypo symptoms, while Free T4 and TSH did not correlate at all.

A good thyroid doctor will treat a  hypo patient clinically by testing and adjusting Free T3 and Free T4 as necessary to relieve symptoms, without being constrained by resultant TSH levels. Symptom relief should be all important, not just test results.

I think by knowing the percentages of T3 and T4 only  we can come to conclusion

[anariodrigues]

T3 1,50 (ref 0,92-2,79)
T4 94 (ref 58-141)
TSH 2,40 (ref 0,35-5,50)
Anti-tyroglobuline <20 (ref <40)
Anti-TPO 85 (ref <35)

TSH is a pituitary hormone that is supposed to accurately reflect levels of the biologically active thyroid hormones, Free T3 and Free T4, but in reality cannot be shown to correlate well with either, much less with symptoms, which are the most important consideration.  Free T3 is the most important because it largely regulates metabolism and many other body functions.  Scientific studies have also shown that Free T3 correlated best with hypo symptoms, while Free T4 and TSH did not correlate at all.

Before going further, please post those T3 and T4 test results and their reference ranges shown on the lab report.
