Question

Graves' disease is caused due to

• A. Hyposecretion of adrenal gland
• B. Hypersecretion of adernal gland
• C. Hyposecretion of thyroid gland
• D. Hypersecretion of thyroid gland

Answer 1

The correct option is D Hypersecretion of thyroid gland

Hypersecretion of thyroxine (T4) secreted by thyroid gland causes Graves Disease. Hyposecretion of these hormones causes cretinism in children and muscular tetany in adults. Changes in hormone levels of adrenal gland can result in either high or low blood pressure as well as cause Cushing’s syndrome and Addison's disease.
