[|Human|] Hi Had my thyroid removed 1 1/2 years ago. Tsh levels keep going up even while on meds. Tried different types, brands, etc...now they want to do an absorption test. Last tsh level was 163 Recent med I d Tirosint 200 mcg daily I m 42, female, 5 8 and 210 pds Fyi can t control weight gain... My question? How bad is having a tsh level at 163 while on meds? What is an absorption study? How is it done?
[|AI|]  Hello and welcome to Chat Doctor, Removal of thyroid gland has led to fall in levels of thyroid hormones. Fall in levels of thyroid hormones lead to increase in levels of TSH.TSH increases as a result of fall in thyroid hormones. Thus, a replacement therapy is required to suppress the elevated levels of TSH. Weight gains that you have mentioned is due to hypothyroidism or low thyroid hormones. Absorption study refers to introduction of radioactive iodine in body, the radio-active iodine gets concentrated in the thyroid gland and thus functional status of the thyroid gland can be determined. Thanks and take care Chat Doctor.
