Primary thyroid hypo- function Flashcards
T4 normal with low to normal T3 level in blood
selenium and copper are needed to cleave T3 from T4 at cellular level.
_____ deficiency is associated with suba-acute thyroid hypofunction
selenium
T4 is a ____ bearing molecule
iodine
low to normal T4 may indicate a need for
iodine
increased T4 can cause a need for decreased
iodine
____ and ____ can bind to T4 and cause a false level of T4 and mask an iodine deficiency
fluoride and chlorine
TSH is usually over ___ in primary hypothyroid dysfunction
4.4
Serum gastrin is usually _____ and ____ 45pg/mL
decrease and below
serum globulin level below 2.4 or above 2.8 indicate
hypochlorhydria
serum phosphorus level indicative of hypochlorhydria
below 3
if triglycerides and cholesterol are increased
primary thyroid hypo-function, hypo-function secondary to anterior pituitary hypo-function and/or adrenal cortical hyper function.
Triglycerides greater than cholesterol suspect
adrenal cortical hyper function and or anterior pituitary hypo function are possible (type 4 alcoholism, Syndrome X, lack of exercise, diets high in carbs should be ruled out)
increased serum magnesium and calcium increased
often increased with primary thyroid hypo-function or hypo-function secondary to anterior pituitary hypo function
*can’t transfer minerals from blood to tissue
the inability to to transfer mineral from blood to tissue is due to
thyroid function, parathyroid function, essential fatty acids and iodine
what is a constant need in both primary and secondary thyroid hypo function?
essential fatty acids
