    suppressed TSH?

    Hi,
    Just wondering what goes on with suppressed TSH? My dr sent me a note to go and get another TSH and T3 and T4? The PA had written the order for TSH without the T3,T4 and my TSH turned out to be 0.09. Does this have any clinical significance? or does it mean I need my levo dose lowered? thanks in advance!!

    It really doesn't matter if you're not having any HyperT symptoms. If you are having HyperT symptoms you need a slight drop to your Levo dose - by taking your Free T levels you may also "prove" that you're not hyperthyroid if you feel fine at the moment.

    Hi,
    Thanks for your input, still waiting for the new results. I feel pretty good except I have been pretty irritable and angry. but I sleep pretty good and have great BP and no racing heart. I recently became a diabetic in September and wonder if the metformin could have influence on my thyroid. thanks again!!

    I have a TSH of 0.17 but my Ft3 is 45% of normal and my Ft4 is 40% of normal. I am not hyperT, but my TSH is suppressed.

    I am now on 1500 mg of Metformin XR in addition to my 112 mcgs of synthroid... well the generic T4 equivalent. My TSH has dropped since taking metformin. My Ft levels have remained balanced and not dropped appreciatively. I am not diabetic, just reactive hypoglycemic with side orders of insulin resistance and PCOS. I do have the antibodies that eventually lead to diabetes, but I am not going diabetic without a good fight.

    So hyperT is not just dependent on TSH.. the ACTUAL thyroid hormone levels are most key. You need to look at how you feel, what your symptoms are and where your ACTUAL thyroid hormones lie before determining a thyroid dose needs raising or lowering.

    Thanks for that input MG, luckily my internist is also an endo so hope after we get the T3, T4 results she will tell me what is going on. I appreciate the input and am on a small dose of metformin only 500 mg once a day and my levo dose is 0.125 mg. thanks again.

    MKG,
    You mentioned antibodies for diabetes.. those lead to Type 1 .. if I remember right ?
    Those are also associated with neuropathic issues.. from the antibodies alone (not the neuropathic issues as a secondary effect of diabetes)
    Yes those need to be closely monitored dear.

    Dream77,

    Thanks. Yeah, I am monitoring all my antibody levels quite regularly.. much to my health insurance company's displeasure... but a girls gotta do what is best. My MD believes that AI issues are strongly tied to the activity of the antibodies. The higher the antibody count the more symptoms and issues that specific AI will cause. I can say from experience that it has held true. Luckily my diabetes antibodies are just below the positive level limit.. BUT we know how meaningful limits can be. My MD thinks one day I will be diabetic as a result, but hopes to push it off 10-20 years with good diet, exercise and the use of Metformin. I hope that we can push it off as well. I can stick myself with needles, I have done it with allergy shots, but I would hate to do it multiple times a day. YUCK!

    MG

    Re: suppressed TSH?

    I've recently found out that adrenal fatigue or very high cortisol levels can cause a suppressed TSH. My cortisol levels are very elevated throughout the day except between 4-5pm, so this explains why my tsh was always so low even when my FT3 and FT4 were within a good range. I never had hyper symptoms.
