Question: I need to write an essay expressing my feelings toward algebra and if I believe students should study it in school. I'm not sure how to start off. Because, personally, I'm very good at math but I absolutely hate it. I just need a good hook to start off!
Such low levels are not always necessary, but decreased T4 and TSH levels are an indication that T4 and RT3 levels are being well depleted (which is often the point of T3 therapy). Hyperthyroidism often causes very low TSH levels and symptoms of hyperthyroidism. Yet proper T3 therapy often causes very low TSH levels without symptoms of hyperthyroidism while providing normal temperatures and a decidedly euthyroid clinical state.
Normally, low levels (less than 5 units) of TSH are sufficient to keep the normal thyroid gland functioning properly. When the thyroid gland becomes inefficient such as in early hypothyroidism, the TSH becomes elevated even though the T4 and T3 may still be within the normal range.
