Which of the Following is Most Responsive to Treatment with Thyroxine

Question

Which of the following is most responsive to treatment with thyroxine?
A) Diabetes mellitus
B) Hyperglycemia
C) Myxedema
D) Graves' disease

Accepted Answer

Myxedema (hypothyroidism) is most responsive to treatment with thyroxine because it is caused by a deficiency in thyroid hormone. Thyroxine supplementation can effectively replace the deficient hormone and alleviate symptoms. Diabetes mellitus and hyperglycemia are related to insulin deficiency or resistance and require different treatments. Graves' disease (hyperthyroidism) may also involve treatment with thyroxine, but additional therapies may be necessary to manage the overactive thyroid gland.
