Extremely low TSH but other thyroid test values normal??
Posted , 11 users are following.
Hi
I was wondering if someone can help me here. My mother, 55 years of age and always been a hypothyroid patient (runs in the family) recently got her thyroid testing done. Surprisingly, her TSH came way too low. i.e. about 0.005, whereas other values, T3, T4 and Free T4 were all within normal range. She has been having bad insomnia for past many weeks (ever since her TSH values went down), has frequent bouts of heart palpitations, is fatigued and has digestive problems-sometimes diarrhea and sometimes constipation. She also is pretty depressed, most likely because she cannot sleep at night at all. Her endo says he won't start any hyperthyroid medicines because the FT4 is normal. However, it has been atleast 2-3 months, her TSH hasn't moved. She was previously taking hypothyroid medicines but now stopped them. She is extremely perplexed as to what to do. Has anyone here experienced something like this or can guide as to what is happening? I have heard about Subclinical Hyperthyroidism, but not sure if this is the case here? Thanks a lot for the help!

If TSH is low, the problem is caused by the pituitary gland. T4 T3 are produced in a separated place. T4 and T3 is produced by the follicular cells.
TSH is a hormones that stimulate the thyroid gland and releases T4 and T3 into our blood.
T4 and T3 will stimulate that controls our metabolism.
T3 main key roles play part in many physiological processes and is more active than T4.
T4 known to be thyroid hormone, thought to be pro-hormone and a reservoir to T3.
TSH is secreted by the pituitary gland. Near to hypothalamus. Both are located at the lower part of our brain.
When TSH is low it means the pituitary gland is overactive. It produces too much hormones to T4 and T3 but somehow your T4 and T3 manage to handle and appeared to standardize the level.
As i already mentioned what does T4 and T3 do to your body, there is no need to worry about it.
Yes you are right. This i called subclinical hyperthyroidism.
I advice to not be stressed or else it triggers the pituitary gland.
Its better to consume organic supplements than medicines. Hope this clear your doubts!
I am on hyperthyroid too now... Get well soon to your mum!
