Goiter can occur due to .. ?
Hypothyroidism

Hyperglycemia
Hypotension
How does goiter in hypothyroidism occur?
Nonfunctional T3&T4 cannot promote negative feedback
Malfunction of thyroid gland and produce many thyroid hormone
Continuous stimulation of thyroid gland
Thyroid gland stimulated to secrete more T3&T4
How does goiter in primary hyperthyroidism occur?
Nonfunctional T3&T4 cannot promote negative feedback
Malfunction of thyroid gland and produce many thyroid hormone
Continuous stimulation of thyroid gland
Thyroid gland stimulated to secrete more T3&T4
The secondary hyperthyroidism found in goiter patient happens due to .. ?
TSH & TRH become abnormal and no longer sensitive to negative feedback
TSH & TRH become abnormal and no longer sensitive to positive feedback
T3 & T4 become abnormal and no longer sensitive to negative feedback
T3 & T4 become abnormal and no longer sensitive to positive feedback
Hypothyroidism can be caused by either thyroid gland malfunction (primary) or Pituitary deficiency of TSH (secondary). How can we differentiate the two causes?
TSH measurement
TRH measurement
FT4 measurement
FT3 measurement
Primary hypothyroidism can cause .. ?

An abnormal level of TSH with normal level of FT4 can be a sign of .. ?
Subclinical hyperthyroidism
Primary hypothyroidism
Secondary hypothyroidism
Hyperthyroidism
