Once my TSH was 0,09 (due to too much T4 pill) my rT3 was tested, it is: 0,45 ng/ml (ref: 0,09-0,35).Could this be false result coz of the low TSH?Thx
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 moreSee 1 more doctor answer
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
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
