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.
In mild iodine deficiency, levels of triiodiothyronine (T 3) may be elevated in the presence of low levels of levothyroxine, as the body converts more of the levothyroxine to triiodothyronine as a compensation. Some such patients may have a goiter, without an elevated TSH.
