Question 1

what does a low tsh level mean?

Accepted Answer

Need to look at T3 (liothyronine): And free t4. Low tsh, depending on the sensitivity of the assay, indicates thyroid hyper-function. However, the suspected hyperthyroidism needs to be confirmed with high levels of T3 (liothyronine) and free t4. All lab tests need to be evaluated in the clinical context and it would be prudent to take up the issue with your doctor.

Question 2

could rhodiola cause low tsh levels?

Accepted Answer

Very unlikely: There is no known effect of rhodiola on the hypothalamus, pituitary or thyroid gland. Low TSH is almost always associated with hyperthyroidism or a pituitary problem. See an endocrinologist for evaluation.

Question 3

can you tell me is 23.69 a high or low tsh level?

Accepted Answer

High: The normal range for a TSH usually is up to 4.5 for most labs. This is a higher than normal number.

Question 4

very low tsh with high normal free t4. twitching. changed dose. how long til levels normal out? still twitching 2 weeks later. had basic neuro exam.

Accepted Answer

What did you: change the dose of? If it's thyroid replacement, it can take weeks for the level to normalize, asumming you're now on the correct dose. If it's an ANTI-thyroid drug, it can takes months to work as it only inhibits the formation of NEW thyroid hormone, not the hormone that's already been manufactured.

Question 5

i am diagnosed with low tsh and normal t3 and t4 level...what does it mean?please suggest me treatment...

Accepted Answer

T3 and T4: A low TSH should not affect your thyroid glands!
If you are having a problem please see an Endocrinologist. Should not be necessary.

Question 6

how long should i wait to be retested for tsh levels? had low tsh of 0.01 but normal t3 and t4. should i wait for 3 months or less? my pcp says i can wait for 1 month?

Accepted Answer

: If you have no symptoms or signs of too much thyroid hormone then no hurry.  While waiting u cam go to uptodate.com and read more.  Then discuss with ur team.

Question 7

i have seronegative sjgren's syndrome, recently i was tested for anti-tpo and anti-tg. my anti-tpo and anti-tg came back high, with low tsh, normal t3 dan normal ft4 levels. what could this possibly mean?

Accepted Answer

: You don't mention any symptoms. I believe those elevated antibodies are consistent with inflammation in the thyroid gland, but a thyroidologist or endocrinologist would have to interpret the significance of the low TSH which could be from release of thyroid hormones due to the inflammation of the thyroid gland. The normal FT4 &amp;T3 may have been transiently elevated and are headed to low territory.

Question 8

can lamotrigine (lamictal) affect tsh levels?

also, what do low tsh mean (if t3 (liothyronine) and t4 are normal)?

Accepted Answer

Not alot: Thyroid interaction is not common with Lamictal, however as with all medications for each individual that can be a possibility. As to your low TSH that is usually a resonse to elevated T3, (liothyronine) T4.  Remember that there can be variations in your thyroid measurements from one time to another. How do you feel.  Do you have thyoid symptoms: cold, tired, fatigued, skin or nail changes?

Question 9

i have low estrogen and low tsh. (but my testosterone, thyroid, and prolactin levels are normal) what could be the cause of low estrogen and low tsh?

Accepted Answer

Estrogen changes: Through the month but TSH is pretty reliable.  When persistently low, you might suff frim hyperthyroidism.

Question 10

can taking too much synthroid (thyroxine) plus cytomel, therefore having a very low tsh level, cause seizures?

Accepted Answer

Possible: Both high and low thyroid states can be associated with seizures. Seizures can be seen in 5-10% of high thyroid states and even more commonly when it is due to an overdose with medication. If you are experiencing this, go to the nearest er as this condition is life-threatening and needs immediate attention. Your doctors will also search for other conditions that may be causing seizures.
