Tsh Low (Overview)

What is this tsh=low supposed to mean?

What is this tsh=low supposed to mean?

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. ...Read more

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. ...Read more

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! ...Read more

What causes low TSH, low T4 and low T3 (liothyronine)?

What causes low TSH, low T4 and low T3 (liothyronine)?

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. ...Read more

What does a normal tsh, low T4 and low T3 (liothyronine) mean?

What does a normal tsh, low T4 and low T3 (liothyronine) mean?

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. ...Read more

What can cause low normal tsh, low normal t4 & low t3 (liothyronine)? Can intense exercise effect it? Can diet effect it?

What can cause low normal tsh, low normal t4 & low t3 (liothyronine)? Can intense exercise effect it? Can diet effect it?

Thyroid: Since your tsh and t4 are within normal limits, you probably have normal thyroid status. Exercise should not affect thyroid blood tests but excessive iodine or lack of it in the diet can affect thyroid status. An endocrinologist is best qualified to answer your question, however. ...Read more

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?

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?

Hypothyroid: Tpo antibodies do not change with treatment. They are indicators of the cause of your hypothyroidism - autoimmune thyroid disease aka grave's disease. Your TSH is slightly suppressed meaning you are getting too much synthroid (thyroxine). Long term side effects of too much synthroid (thyroxine) include an increased predilection for osteoporosis and atrial fibrillation, therefore a slight reduction in dose is warranted. ...Read more

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?

It's near average: Although all the numbers are running in the right direction for an activated thyroid (autonomous nodule secreting thyroid hormone is my guess).
In any case, follow up repeats are a good idea for tests that show an abnormality but not a definite nor significant nor consistent one. ...Read more

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?

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. ...Read more

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?

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. ...Read more
