Question 1

what is this tsh=low  supposed to mean?

Accepted Answer

May be hyperthyroid: If the TSH is below 0.1, and you are not on medication for the thyroid, then you are probably hyperthyroid (rarely a pituitary problem.) see an endocrinologist because this can lead to serious problems if not treated. If you are on medication and the TSH is low but above 0.1 and you feel good, you may have just received a slightly more potent batch of med.

Question 2

tsh low. synth. decr. by .5 pill/week. i accidentally incr. by .5/week. twitched. tsh even lower. corrected dose and skipped pills. 2 wks still twitch?

Accepted Answer

TSH: TSH is not the only thyroid level you need to know. You must also get your doctor to order T3 and T4 - the hormones made in your thyroid gland.

TSH low is not a sufficient diagnosis to require Synthroid (thyroxine). You only need thyroid replacement (Synthroid (thyroxine)) if you blood level of T4 or T3 is low.

Question 3

cardio exercise  makes me feel  anxious  and jittery, i have anxiety  and  this supposed to help  but it only makes it worse , have normal tsh & low bp?

Accepted Answer

Start slow: Exercise is good for your health in so many ways.  Keep exercising.  Start slow - walking is a great way to start - and gradually increase your time and intensity.  Learn some relaxation techniques such as meditation or self hypnosis to help calm yourself.  Good luck!

Question 4

what causes low tsh, low t4 and low t3 (liothyronine)?

Accepted Answer

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, it would have helped to know the actual values. Even though all these parameters may be low, these may yet be in the normal range.

Question 5

what does a normal tsh, low t4 and low t3 (liothyronine) mean?

Accepted Answer

Perhaps nothing: Such tests need to be repeated. If the T4 and T3 (liothyronine) were measured as total T4 & T3 (liothyronine) it may mean only that the binding proteins of thyroid hormone are low. Ask your doctor what was done and his/her interpretation.

Question 6

i have hypothyroid and have been on synthroid (thyroxine) 112mcg  test results are tpo high 173, tsh low 0.126, t4 free normal1.38, is there a need to change meds?

Accepted Answer

Hashimoto's: The elevated anti-TPO indicates hashimoto's thyroiditis, but you basically know that since you are hypothyroid.  The low TSH may suggest that the dose of synthroid (thyroxine) is very slightly too high, even though the ft4 is normal, but if you are feeling well (no symptoms of hyper, not heart problems, bones ok) i might wait 3-6 months and check again.

Question 7

tsh 0.01, t3 (liothyronine) free 4.3, t4. free 1.8 ? tsh low t3 (liothyronine) very slightly elevated t4 high normal, what is this? tsh usually normal? could stress do that?

Accepted Answer

Doubtful: This sounds like Grave's disease ( hyperthyroidism) or the very earliest phases of Hashimoto's thyroiditis-please consult an endocrinologist ASAP&gt;

Question 8

tsh 0.01, t3 (liothyronine) free 4.3, t4. free 1.8 ? tsh low t3 (liothyronine) very slightly elevated t4 high normal? pcp says nothing is wrong?

Accepted Answer

PCP is wrong: Hi. Please get a second opinion from an endocrinologist. Something IS wrong (at least not normal). You have a form of hyperthyroidism. Following your thyroid function over time would help. The hyperthyroidism could be a transient thyroiditis or could evolve to be more hyperthyroid, or could be stable. Getting a nuclear medicine thyroid uptakes and scan would help the diagnosis too. Good luck!

Question 9

tsh 0.01, t3 (liothyronine) free 4.3, t4. free 1.8 ? tsh low t3 (liothyronine) very slightly elevated t4 high normal? pcp doesn't think much, repeat in 6 weeks?

Accepted Answer

Thyroid levels: I think I already answered your question about cause.  The elevation in FT4 and FT3 is subtle, depending on the lab just barely at or above the normal range. However the low TSH makes me think it is real. Are you having symptoms (palpitations, heat intolerance, tremor, nervous)? Repeating the labs is a good idea, but I would prob not wait 6 weeks. You may need an Endocrinologist.

Question 10

my body is swollen (ex. peeing is forced out) some inflamm. taking ains. nrml blood test except high anti-tg/t4 & tsh low normal. what can this be?

Accepted Answer

Probably not thyroid: Your symptoms are likely not related to any thyroid problem.  A high antithyroglobulin antibody could indicate underlying autoimmune thyroid disease, but if the TSH is normal, it means your thyroid function is still normal.
