Do I have hypothyroidism ?

[Worriedgirl098]

Hi,

In October I went and got my physical and they took blood work.

My TSH is at 3.25
And my FT4 is 1.40

Should I be concerned about this?
Sometimes I feel tired, there has been a few times (very rare) where I get dizzy, and I did put on 10 pounds (due to depression) but lost 5, struggling to lose last 5.

There is inadequate information to determine if you are hypothyroid.  TSH is a pituitary hormone that is affected by so many things that at best it is only an indicator, not a diagnostic like doctors believe.  That said, your TSH is higher than typical of people with no thyroid issues.  So it would be a good idea to test for the antibodies of Hashimoto's Thyroiditis.  Those tests are Thyroid Perosidase antibodies, (TPO ab) and Thyroglobulin antibodies (TG ab).  

Of much greater importance as indicators are symptoms, and also levels of the biologically active thyroid hormones, Free T4 and Free T3.  You have a number of symptoms that  are frequently related to hypothyroidism.  Your Free T4 appears adequate, but you were not tested for Free T3, which is the thyroid hormone used by all the cells of your body.  T4 has to be converted to T3 to be metabolized.  Many doctors think the T4 is just automatically converted to T3, so no need to bother with a test for Free T3.  Wrong.  There are a number of variables that affect conversion of T4 to T3, so you should make sure they always test for both Free T4 and Free T3.  In addition there are other variables that can affect the desired outcome:  having adequate tissue thyroid effects.  

You can read about this in the following link.  I highly recommend reading at least the first two pages and more if you want to get into the discussion and scientific evidence for all that is recommended.

Note on page 2 that in addition to always testing for Free T4 and Free T3,  it is recommended that you should also test for Reverse T3, cortisol, Vitamin D, B12 and ferritin.  All are important for diagnosis and treatment.  

A good thyroid doctor will treat a hypothyroid patient clinically by testing and adjusting Free T4 and Free T3 as needed to relieve hypo symptoms, without being influenced by resultant TSH levels.  Symptom relief should be all important, not just test results.  If you doctor is unwilling to  treat you clinically, as described,  then you will need to find one that will do so.
