Side Effects Of Low Tsh Levels
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
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
I am diagnosed with low TSH and normal T3 and T4 level...What does it mean? Please suggest me treatment...
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. ...Read more
Can Lamotrigine (Lamictal) affect TSH levels? Also, what do low TSH mean (if T3 (liothyronine) and T4 are normal)?
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? ...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?
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
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?
Hyperthyroidism and weight gain, can a low TSH level cause weight gain? And how would menopause effect TSH level?
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
Can taking too much Synthroid (thyroxine) plus cytomel, therefore having a very low TSH level, cause seizures?
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. ...Read more
I had a total thyroidectomy due to cancer. My lab shows low tsh but t4 and t3 (liothyronine) levels are normal indicating correct dosage why would my tsh be low?
TSH may be low simply because your thyroid meds are doing enough to keep the TSH at a low level.
If you are feeling OK just relax and enjoy life! ...Read more
Could a low TSH (.28) & normal T3 (liothyronine) & T4 levels mean a Pituitary issue? Or is that more typical of hypothyroidism? Would high Chloride (111) effect it?
Means pituitary is: A TSH of 0.28 with normal free T4 and free T3 (liothyronine) likely means the pituitary is working properly. A TSH of 0.1-0.4 is lower than the reference range, which means about 2.5% of normal people have a TSH or 0.1-0.4. Thus, one hopes she is normal. Her endocrinologist can follow and recheck her levels in 4-6 weeks to confirm that her levels are stable (TSH not dropping lower; T4 or T3 (liothyronine) not above normal). ...Read more
Hair loss for 18 months in crown area, first due to stress, then perhaps due to very low TSH as a result of Thyroxine dose increase. Iron levels fine. Hair is now finer / softer and continues to shed - will my hair ever go back to how it was?
Wrong assumptions: Iron level not relevant. "Stress" probably not a factor. Very low TSH because of overdosed thyroid probably not part of it. Thin hair on top is very common as women get older. Other meds? Birth control? Menstrual history? Pregnancies? Weight change? When you see a dermatologist be prepared to detail these items. You might be helped by spironolactone or dutasteride. ...Read more
Could a pituitary tumor cause temporary one sided facial drooping without paralysis? Low TSH (normal T3 (liothyronine) & T4) Low ACTH. Waiting on more test results.
Facial nerve: Any structure that affects the facial nerve along its course from the brain can cause a droop. Pituitary tumor can cause droop in eye, visual changes etc. Its anatomical and the facial nerve has several branches, temporal, zygomatic, buccal, maxillary and mandibular. Good luck. Stroke, Hemifacial spasm and bells palsy other alternative possibilities. ...Read more
Low TSH unlikely: Thyroid cancer usually does not cause a low TSH (unless you are taking thyroid hormone). Most thyroid cancers do not function as well as normal thyroid tissue. Elevated thyroglobulin is a nonspecific finding, seen in most disorders of the thyroid. It can serve as a tumor marker for recurrent thyroid cancer as long as the thyroid has been completely removed. High tg has nothing to do with tsh. ...Read more
Thyroid labs: Hi. See an endocrinologist. Make sure it's a free T4 (not a TOTAL T4). If you have low TSH and a low free T4, that's compatible with pituitary disease causing hypothyroidism (so called "secondary hypothyroidism"). IF you have that (not saying you do), you need to be checked for pituitary problems and other pituitary deficiencies (adrenal, most promptly); If u have secondary hypothy, CHECK ADRENALS ...Read more
Stress can increase tsh, but how high cortisol causes low TSH where as stress causes high cortisol production.?
Cortisol: This is a very complex system. In very basic terms cortisol is produced in response to stress and feeds back inhibiting production of itself (inhibiting crh and acth). Cortisol also inhibits TSH production (as well as growth hormone, estrogen, testosterone and lh production). Thus limiting the response to stress. It is though in chronic stress this feedback mechanism breaks down. ...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
How low?: If these were taken during a time that you were emotionally distraught, and they are not strikingly removed from the reference range (which is set so that several percent of healthies fall outside), your physician will repeat them when your life gets better. If way-low, pituitary disease is a concern. ...Read more
I have a low TSH due to probably excess eltroxin have been hypothryroid for 25 years. Have started getting lots of skipeed beats tsh.05?
See your doctor: This problem can only be solved by seeing your doctor and being evaluated face-to-face. After a thorough examination, your doctor should be able to tell you what's wrong and what to do about it. ...Read more
Unrelated: Heel pain is not a symptom of thyroid disease. When you say low TSH, do you mean in the range of 0.1-0.4 or less than 0.1? A slightly low TSH of 0.1 to 0.4 is usually a benign normal variation whereas a TSH of less than 0.1 could be a sign of an overactive thyroid which would require further testing and possibly treatment. ...Read more
No: Not if those values are within the lab's stated and assayed normals, and if your not on any medication to lower active thyroid hormones. ...Read more
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
Nothing usually: Borderline is still within the normal range. Ask the physician who ordered the test why he got both and what his/her interpretation is. ...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.
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
Can you stop taking Synthroid (thyroxine) after (5-6)years of taking it? Borderline -low TSH is why it was prescribed. Dose. 050mcg.
Synthroid (thyroxine): You must mean a borderline high TSH for an underactive thyroid. Anyhow, the thyroid does not revert back to its normal level on its own, it ages with us and needs frequent monitoring, I would suggest not to stop it, but this is something you need to discuss with your doctor who knows you best. ...Read more
Struggling with very low TSH 0 01 for 1 yr. Compliant with levo although doc keeps lowering it. No supps etc that would cause malabsorption. Ugh!
Over replaced: As your TSH is low and you're having symptoms of hyperthyroid (i presume), the answer is simply that your dose is too high. Dropping it carefully, as your doctor is doing, should work to bring your levels back in to control. (low TSH = high thyroid). ...Read more
Yes, transiently: Hashimoto's thyroiditis can go through a phase of thyroid hyperactivity early in the course of disease and that would be associated with low TSH. Sooner or later enough thyroid is destroyed that thyroid functions declines and TSH rises. ...Read more
Need further eval: The low TSH needs to be addressed as it can cause problems for you. In the presence of thyroid nodules, you will need a thyroid uptake and scan to make sure the nodules are not producing too much thyroid hormones. Treatment then would be antithyroid drugs, radioactive iodine, or surgery. You should not be doing nothing with a low tsh. ...Read more
