E05: Thyrotoxicosis [hyperthyroidism]

E05.2: Thyrotoxicosis with toxic multinodular goitre

The thyroid is a small organ at the bottom of the neck. The thyroid gland needs iodine to produce important messenger substances for the body. These messenger substances influence the heartbeat, digestion, and body temperature, among other things.

Some nodules have formed in your thyroid gland. Thyroid nodules develop when tissue in the thyroid gland thickens. Thyroid nodules can form many thyroid messenger substances. The thyroid gland nodules have made your thyroid gland larger than usual.

Having too many thyroid messenger substances can cause a range of problems. For example, you may be restless or have a rapid heartbeat. You may also break out in a sweat often and lose weight.
