Question

Quizplus · Accepted Answer

A hyperactive thyroid gland usually leads to elevated levels of thyroid hormones, which would be reflected in increased levels of total and free T4 hormone in blood serum. An enlarged thyroid gland, increased TSH in blood serum, proptosis and diplopia, and abnormally low blood glucose level are all possible symptoms of hyperthyroidism. However, decreased levels of T4 hormone would not be expected in a hyperactive thyroid gland.
