..tsh goes from 19.45 in June to .09 in Aug this had been going on for a year . has anyone had this problem?
You might find a little useful information about TSH testing at the discussion that I posted yesterday on l5 Sept 2013 -- look for Nickilou's question, "Levothyroxine - Can anyone help me to understand…." which she posted on 3 Aug 2013. Nickilou's main question was about heart symptoms that she was having, so just skip the first paragraph of the answer and click on "expand." In the middle paragraphs (they are kind of long and detailed), you'll find some more information about the blood test which measures the Thyroid Stimulating Hormone that is produced by your pituitary gland.
As you know, the pituitary is located in a person's brain. It "receives information" from the body telling the pituitary how much thyroid hormone the person has available and how much, if any, the body still needs. When the "information" says there is too much thyroid right now, the pituitary cuts back on sending out the hormone that stimulates the thyroid gland (TSH); if you have your blood drawn at this time, your TSH might be like the .09 you had in August. If the pituitary gland receives "information" that there is not enough thyroid in the body right now, then the pituitary becomes "excited" and sends out plenty of stimulating hormone, trying to force the thyroid gland to make more thyroid hormone. If your blood is drawn at this time, your TSH might be like the 19.45 you had in June. That is certainly "above range" (high).
There is something important that you should check on: you only have a single (one) thyroid gland, so are you sure it was your thyroid that was removed and not your parathyroids? Knowing this will help you get the kind of responses you are hoping to find here at Drugs.com.
