thyroid tests

  1. I have tried looking this up w/o success so if someone can please TSH is 0.32 with norm range being 0.49-4.67. My md says this means I am HYPER thyroid, not hypo. before she begins to tret she wanted to recheck and also ordered a free T4 today. If a low TSH does mean hyper, how is that treated? thanks, tillie

    My wife was hyper after the birth of our first son. (Doc says it may have had something to do with left over male hormone) It was not diagnosed until she was pregnant with our second.

    The Doc told her most of the time it will subside on it's own. She took a couple of different types of meds, while waiting for it to subside. The only one I can remember is inderal. (Weird huh???)

    However, it did not subside!
    She was given the choice of radio-iodine treatment or a thyroidectomy. Of course since she was pregnant, we picked thyroidectomy. We now have a perfectly healthy 3 month old boy.
    (Of course this is long story, short)

    Check out these sites, they are very comprehensive.

    I will e-mail you with the other medication name. I have to ask my wife.
    Sorry I can't give you a professional RN view, endocrinology is not my area. I sure we have some endocrinology nurses out there.

    Hope this helps!

    It does sound weird that a low TSH (thyroid stimulating hormone) is hyperthyroid, but it is because there is an excess amount of thyroid hormone present making TSH low in an attempt to control thyroid hormone production.

    There are 3 treatment option that I am aware of:

    1-Antithyroid meds.....Methimazole (tapazole) and propylthiouracil (PTU). These drugs accumulate in the thyroid tissue and inhibit hormone production. PTU also blocks the conversion of T4 hormone to the more active T3 hormone.
    There are medications available to treat the symptoms caused by hyperthyroid, most commonly a rapid heart rate. Which is why roachell's wife was on inderal. It counteracts the increased metabolic effect of the thyroid hormones, but do not alter the actual hormone level

    2-Radioactive iodine...given orally (either by pill or liquid) on a one-time basis. The radioactive iodine is picked up by the cells in the thyroid and destroys them. Since iodine is only picked up by thyroid cells, the destruction is local and there are no widespread consequences to this therapy.

    3-Surgery...This is common for recurring Graves' disease, those with severe cardiac involvement, patients who are pregnant (like roachell's wife), or those who can't tolerate antithyroid drugs. Surgery is less common today because of radioactive iodine therapy and trapazole and PTU

    Obviously you have choices...hope this helps...good luck!

    thanks to both of you for your help. My MD is puzzled b/c all the symptoms I have been whining about (fatigue, dry skin, losing my dry hair, brittle nails , etc) all point to low thyroid...guess we will see what the latest blood test show! thanks again.
