TSH (thyroid stimulating hormone) increases the activity of the Sodium-Iodine Symporter (NIS) that drives iodine into the thyroid and into the cells of the other organs. That is the reason that the TSH blood levels increase when patients are taking iodine â the TSH is needed to drive iodine into the cells.
When the level of thyroid hormones (T3 & T4) drops too low, the pituitary gland produces Thyroid Stimulating Hormone (TSH) which stimulates the thyroid gland to produce more hormones. Under the influence of TSH, the thyroid will manufacture and secrete T3 and T4 thereby raising their blood levels. +The pituitary senses this and responds by decreasing its TSH production. One can imagine the thyroid gland as a furnace and the pituitary gland as the thermostat.
