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

hyperthyroidism and weight gain, can a low tsh level cause weight gain? and how would menopause effect tsh level?

Accepted Answer

No: Rarely hyperthyroidism manifested by a low TSH and elevated thyroid hormones can cause increased hunger  leading to weight  gain. Most hyperthyroids lose  (muscle) weight. Menopause has no effect on TSH levels, but as we age hypothyroidism with increased TSH becomes more likely. 20% of women on medicare have elevated TSH and have frank or subclinical hypothyroidism.

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

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.

Question 5

my tsh level is low 0.43   what does this mean exactly?

Accepted Answer

More workup: Currently, it points to hyperthyroidism but you need to complete the work up to know for sure.  At the very least, i would repeat the TSH along with the free hormones T4 and t3 (liothyronine).  If they also point to hyperthyroidism, then proceed further to find the exact cause for this.  Tsh alone does not give you a complete picture.

Question 6

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 7

my tsh level is 0.02 (low?) and t4 is 0.66 (low?)  what does this mean.  i have been on synthroid (thyroxine) 50 mcg for hypothyroid for 3 months

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, given your TSH level you are on a sufficient dose of  medication. Please do keep your follow-up appointments for monitoring the treatment.

Question 8

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 9

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 10

my tsh level in my last blood test was 3.48 which means my thyroid level is low. i have never had a thyroid problem before but i am now in the early stages of pregnancy. what is the recommended daily dose of levothyroxine to correct my thyroid level?

Accepted Answer

Not low: A TSH level of 3.48 is normal. Your thyroid is functioning normally. Treating yourself for perceived thyroid disorder is not a good idea. You should consult your doctor.
