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.
1 Therefore low cortisol disrupts normal thyroid signaling leading to hypothyroid.  High cortisol levels decrease the conversion of thyroxine (T4) to triiodothyronine (T3) and increase levels of reverse thyroid hormone (rT3). Together this means lower thyroid function and hypothyroid.
