Thyroid stimulating hormone (TSH) is the signal that the brain sends to the thyroid to tell the thryoid how much hormone to make. Markedly high levels are almost always due to an underactive thyroid gland (hypothyroidism). Mildly elevated levels are often normal.
is a 3.89 tsh level high?
high TSH than the normal range means hypothyrodism.
Yes, absolutely! Even when using the older measurements TSH 0.3 - 5.0, that is exceptionally high
The "normal range of TSH is 0.3 to 3.0 μIU/mL. A TSH level that is above that range would be considered "high". The pituitary produces TSH to tell the thyroid glands to produce more thyroid hormones. If the thyroid glands to not respond, the pituitary produces greater and greater levels of TSH. A TSH level that high indicates that there is something significantly wrong with the thyroid glands, and the patient should be prescribed thyroid replacement hormones.
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.
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.
low tsh is when you have low tinactimine sorachome hendrocytosis.
bannana
yes
Vitamin B12 helps in reducing the TSh levels and controllng hypothyroidism (I was prescribed high dosages of B12 as i had high TSH levels due to hypothyroid)
Absolutely, get to your Dr. or get a better Dr.
