undetectable TSH, normal free T4
I have just recieved test results showing TSH <.01, normal free T4. I am 35 years old, very active woman, no prior history. My last thyroid test 2 years ago checked out fine. I don't have overt signs of hyperthyroidism. I'm really worried the problem may be with my pituitary gland! How common is it for a woman with my demographics to get these results?

Hi
I am in exactly the same situation. TSH 0.05 and T4 10.3. The first dr said to increase the Diotroxin (2 tablets per day), the second dr said to decrease (.75 tablet per day). I have more hyper symptoms than hypo symptoms. Not the heart beat though, but that might be because of the Seroquel I take ( it seems to slow your heart ). Heart rate is 89 beats per minute, blood pressure is normal. Lab report does state subclinical hyper thyroid though. I did take 2 tablets per day for 2 days before seeing the second dr and I felt absolutely awful. I had no energy whatsoever and could not even climb 10 stairs without running out of breath. I have noticed over the last 3 to 4 months that I at times would lose weight but other days I would pick it up quickly again. Very much like a yo-yo. So all of it tells me the t3 might be too high. I am going on what my body is telling me here, cause it seems the dr's aren't really certain either.
So I think I'll maybe just take the .75 for 4 weeks and then have everything re-tested like the 2nd dr suggested and I will definetly take the article mentioned above with me when I go back. Thank you.

Annekeg - I strongly recommend you go back to your doctor or get a second opinion. i have had TSH <0.01 for years now and it's always the same thing - the doctors don't do anything. Even though i complain constantly about extreme fatigue, inability to concentrate, etc etc. Then one doctor recommended that i take low dose of neomercazole (methimazole) and it totally changed my life - after years of this roller coaster - i had good energy (just the right amounts), was productive at work, was in a better mood, and could sleep better. You should definitely ask your doctor to consider this.
for everyone with low TSH and normal T3/T4 - it's probably subclinical hyperthyroidism, and if untreated you not only feel bad, but you actually have accelerated bone loss. There were some trials done to treat subclinical hyperthyroid patients with low levels of methimazole and bone loss was significantly reduced (see http://www.jfponline.com/pdf%2F5506%2F5506JFP_ClinicalInquiries6.pdf)

Hi,
I just got my results in yesterday.
TSH 0.01
T4 and T3 and Free T4 all normal
Potassium low: 2.7
Symptoms are: very tired, fast irregular heart rate, short of breath, sweating, muscle pain/weakness, shaking hands. I am only 44 years young.
My doctor sent me home without an explanation for the low TSH.
I am concerned especially because the fas heart rate (around 120).
Hope to read more from you and every ones experiences and wish every one the best.

i was diagnosed with thyroiditis a year ago. my tsh was .004, high ft3, and high antithyroglobulin. everything else was normal. i went from hyperT to hypoT, and now i'm on synthroid. so yes, you need to get the ft3 and anitbodies tested. and then you may need a nuclear scan to see how your thyroid takes up iodine. that was how graves and thyroiditis was distinguished in this situation.
try not to get too worried (in know easier said than done)....but be ready for the physical/emotional roller coaster of thyroid issues. you can go from feeling great (hyper) to feeling tired, exhausted, apathetic (hypo) overnight.

I was waiting for an expert to answer you. I'm pretty new at this.
I also had undetectable TSH with normal FT4. I'm a 51 yo female. I had no symptoms except those that can be explained by menopause.
You need more tests. My Drs. tested for the most comon things first. Every test came back neg. Not Hashimoto's, not Graves, not thyroiditis. All blood work was normal except high FT3.
I do not think this is a common problem, but it happens. Before you jump to the conclusion that it is a pituitary problem, get your FT3 checked.
