Yes, for some people....
yes
Thyroxine free index. "elevated TsH and low fT4 or fTi indicates primary hypothyroidism due to disease in the thyroid gland. a low TsH and low fT4 or fTi indicates hypothyroidism due to a problem involving the pituitary gland. a low TsH with anelevated fT4 or fTi is found in individuals who have hyperthyroidism."
Yes, that indicates a pituitary problem.
In graves disease, TSH level is lowered by thyroid gland, when it makes more thyroid hormone.
There were a numerous symptoms of a low TSH level some are : feeling tired, weak or depressed, dry skin and brittle nails, not being able to stand the cold,memory problems.
TSH is thyroid stimulating hormone. It is produced by the pituitary to turn on the thyroid gland. If TSH is low, that is because there is sufficient (or too much ) thyroid hormone in the body, so the pituitary needs less to keep the thyroid functioning. Thyroid hormones measured in lab tests are usually FreeT4 and FreeT3.
TSH is not a thyroid hormone - it is a pituitary hormone called Thyroid Stimulating Hormone. It's job is to tell the thyroid how much thyroid hormone to produce. This is called a negative feedback system.The thyroid produces hormone.The brain reads that there is insufficient hormone in the bodyThe pituitary gland in the brain produces more TSH that turns the thyroid onMore TSH means the thyroid produces even more thyroid hormone.When there is too much thyroid hormone in the body, the pituitary turns off TSH as the body doesn't need any MORE thyroid hormone.If the brain, pituitary and thyroid are working properly, thyroid hormones T4 and T3 will be high (hypERthyroidism) when TSH is low, and thyroid hormones T4 and T3 will be low (hypOthyroidism) when TSH is high.
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.
blood level gets low
TSH is thyroid stimulating hormone. 9.7 is the concentration of TSH in your blood.
A thyroid stimulating hormone (TSH) test is an initial test used to determine how your thyroid is functioning. A high TSH level indicates that the thyroid gland isn't making enough hormones, causing hypothyroidism. Conversely, if the TSH level is low it indicates an overactive thyroid, known as hyperthyroidism. The TSH normal level range that most physicians refer to is .3 to 4.5.
