In graves disease, TSH level is lowered by thyroid gland, when it makes more thyroid hormone.
Hyperthyroidism would be a condition in which T3 and T4 are at increased levels.
As thyroxine levels increase the amount of TSH produced will decrease. On the other hand, when TSH levels increase the thyroxine levels will decrease. This is what causes the TSH/thyroxine levels to fluctuate.
Your pituitary gland produces the actual thyroid stimulating hormone and regulates your TSH level; and it is the TSH levels produced by the pituitary gland that tells the thyroid to go to work. Low levels of thyroid hormone tells the pitutary to make TSH.
Thyroid levels are measurements of the thyroid hormones in your body. Low TSH suggests you have too much thyroid hormone circulating. High TSH suggests you don't have enough thyroid hormone circulating.
TSH levels show ranges. For newborns TSH normal levels should be: 3.0-20 mIU/L. For adults up to age 60 TSH normal levels should be: <10 mIU/L For adults older than 60 TSH normal levels should be: Males: 2.0-7.3 mIU/L Females: 2.0-16.8 mIU/L

low tsh is when you have low tinactimine sorachome hendrocytosis.
.450 - 4.500
Normal TSH levels for adults are 0.5-5.0 mU/L.
High levels of TSH initially increases the level of thyroid hormone (TH). When the TH levels get high, the feedback mechanism starts to work: The excess amount of TH in the blood signals the pituitary gland to decrease secretion of TSH, which decreases the amount of TSH that is secreted by the pituitary gland, and maintains homeostatis.
