Hyperthyroidism Hypothyroidism
-Excessive circulating thyroid -Inadequate amount of circulating
hormones, everything is HIGH thyroid hormones causing a ↓ in
(furnace turned up) metabolic rate, everything is LOW,
furnace turned DOWN
Causes Most common: Grave’s Disease Primary Hypothyroidism: Destruction of
Other causes: thyroid tissue or defective hormone
Toxic nodular goiter synthesis
Thyroiditis
Excess iodine intake Secondary Hypothyroidism: Pituitary or
Pituitary tumors hormone dysfunction
Thyroid cancer
Types Subclinical hyperthyroidism: ↓ TSH, Subclinical Hypothyroidism:
normal T3 & T4 TSH > 4.5, normal T4
Overt hyperthyroidism: ↓ TSH, ↑ T3 Non-Thyroidal Illness Syndrome
and T4 (NTIS): ↓ T3, T4, & TSH
Diet High calorie, high carbs, low fiber, Low calorie diet
AVOID: caffeine & seasoned foods
