Pick out the false statement with reference to exophthalmic goitre:

• A. failure of thyroid secretion causes this disease
• B. thyroid gland enlarges
• C. eye balls bulge
• D. person suffers from high temperature, nervousness and irritability

Answer 1

The correct option is A failure of thyroid secretion causes this disease

Exophthalmic goiter is the most common cause of thyrotoxicosis. It affects women more commonly than men. High levels of thyroxine are secreted, which are not subject to the normal secretion of TRH from the hypothalamus and TSH from the anterior pituitary. Exophthalmos (protrusion of the eyeballs), due to deposition of excess fat and fibrous tissue behind the eyes is often present in Graves disease.

So correct answer is a failure of thyroid secretion causes this disease.
