Remember: Hyperthyroidism - which appears to be the case with based on your biochemical studies - can present with a spectrum of symptoms. Not everyone has tremor, palpitations, anxiety, emotional lability, weakness, heat intolerance, increased perspiration, and/or weight loss. But your testing does suggest that you need further evaluation for the cause of your hyperthyroidism. ...Read more

Overactive thyroid: You have an overactive thyroid. Sometimes this is the early phase of what eventually will become an underactive thyroid (thyroiditis). It will need treatment and close followup. Fortunately, there are excellent medications that can normalize your function either way, albeit slowly, so stay in close touch with your doctor! ...Read more

With low TSH levels hyperthyroid is off the table right? What other issues, full normal blood panel, could cause a major weight loss?

With low TSH levels hyperthyroid is off the table right? What other issues, full normal blood panel, could cause a major weight loss?

Low tsh?: Normal TSH values fall within a range. If the TSH is low, or in other words, below the lower limit of normal, it may suggest your thyroid is overactive. When your body produces too much thyroid hormone, the brain tries to compensate by making less tsh, and therefore the levels show up low. ...Read more

27 yrs old. This years blood work showed: Low TSH, and total T-3 and free T-4 are both high. Last year's test were fine. What could thus indicate?

Mild hyperthyroidism: Unless you are taking thyroid medication (and taking too much) this could mean mild hyperthyroidism. If your doc measured TSH, FT3 and FT4, (s)he must have suspected something. Most likely cause of hyperthyroidism in a 27 yo woman is Graves disease or one of several forms of thyroiditis. You may need to see an Endocrinologist. ...Read more

What does a low TSH score of .08 indicate? I have been takin levothyroxin for 9 years and my last blood test shows a TSH score of .08.

What does a low TSH score of .08 indicate? I have been takin levothyroxin for 9 years and my last blood test shows a TSH score of .08.

Too much levothyrox?: That result is below the usual target of 0.5-5, indicating that there may be too much T4 (levothyrox) in your system. 1. the doctor who prescribes your T4 should determine whether a dose reduction is needed. 2. if you are feeling well, the first thing to do may be to repeat the test. 3. after 9 years, it is possible that your T4 requirement has indeed gone down and your dose should be lowered. ...Read more

Pregnant with low TSH ultrasound of thyroid found mulitnodular thyroid. Biggest nodule hypoechoic 1.3 x 1.0 x 1.3 CM in with increased blood flow?

Hyperthyroid: Hi. You're hyperthyroid by TSH. That can be safely treated during pregnancy if necessary. The nodules have a high likelihood of being a "toxic (hyperthyroid) multi nodular goiter". Wait until you deliver and are done nursing for a few months, and then measure 123-Iodine thyroid uptakes and scan. A "cold" nodule will need biopsy to check for cancer; "hot" nodules don't have that risk. Good luck! ...Read more

What does a low TSH level mean?

What does a low TSH level mean?

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. ...Read more

Could rhodiola cause low TSH levels?

Could rhodiola cause low TSH levels?

Unlikely but...: Rhodiola is known to improve thyroid function and thus might be expected to reduce TSH levels somewhat (though more research on this is needed). However, a low TSH tends to be a sign of hyperthyroidism and, as far as i know, rhodiola is not known to stimulate the thyroid to the point of hyperthyroidism. ...Read more

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.

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. ...Read more

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. ...Read more
