Answer 1

Ex-ophthalmic goitre, over secretion of thyroxine.

Explanation:

Exophthalmic goitre, or Graves’ disease, is characterized by bulging eyes and swelling in the neck region. This disorder occurs when the thyroid gland secretes too much thyroxine. Excess thyroxine increases metabolic rate, leading to symptoms such as rapid heartbeat, restlessness, and bulging eyeballs.
