Thyroid TSH level went down

[VKDSKF]

My TSH level 2 months back was 52 after medication it reduced to 27. Kindly suggest what does this indicate

It indicates that your Levothyroxine (assuming that is what you are prescribed) is working correctly by bringing your TSH down.

The aim of a treated hypo patient generally is for TSH to be 1 or below or wherever it needs to be for FT4 and FT3 to be in the upper part of their respective reference ranges when on Levo if that is where you feel well.

You now need retesting every 6 weeks, with an increase of 25mcg Levo each time, until your levels are where they need to be for you to feel well.

It's important to test not just TSH on it's own, but to see where your actual thyroid hormones are as well - FT4 and FT3.

It indicates that your thyroid med is doing exactly what is required of it, although at 27 it still has a little way to go. TSH stands for Thyroid Stimulating Hormone which means that when the pituitary gland senses thyroid hormone levels are low, it produces more TSH to stimulate the thyroid to produce more hormones. Unfortunately if a thyroid is functioning poorly or not at all, or is absent, due to illness such as autoimmune thyroid disease (aka Hashimoto's) for instance, or a post-partum disorder say, the thyroid can't respond as needed. Then we need to take replacement thyroid hormones such as Levothyroxine, instead. When the pituitary gland senses that thyroid levels have then risen, it decreases its own production of TSH. And hence why your TSH levels have dropped. However, as it is a pituitary hormone you cannot adequately judge how you are reacting to the Levo without also testing FT4 and FT3 - these are the hormones in the blood that are not attached to their carrier proteins ie they are "free" (hence FT4 and FT3), and so can therefore be taken into the cells and used by the body. You will need to have regular 6 weekly tests and adjustment made to your dose as necessary, until you are optimally medicated and hopefully symptom-free.
