The thyroid gland in mammals plays a central role in the regulation of development and basal metabolism.
Most labs say that a normal serum TSH level is somewhere between 0.4 to 4.0 mIU/L, and that a TSH level of 10 mIU/L or higher is indicative of hypothyroidism
TSH (Thyroid stimulating hormone) tells your thyroid how much thyroid hormone it needs to make. If the thyroid hormone levels in your blood are too low, your pituitary gland makes larger amounts of TSH to tell your thyroid to work harder.
A TSH over 10 mIU/L has been linked to an increased risk of coronary heart disease and heart failure, which is why you' will probably want to seek treatment if your TSH is close to (but still under) that upper limit
Yes, the release of estradiol can increase TSH levels during periods.
