What is thyroid disease?


Thyroid disease is a condition that affects the thyroid gland, a butterfly-shaped gland located in the front of your neck. This gland plays an important role in controlling your metabolism. Different kinds of thyroid diseases affect either its function or structure.

The thyroid gland is controlled by the pituitary gland and hypothalamus, so disorders of these tissues in the brain can affect thyroid function and cause thyroid disorders. The production of thyroxine (T4) and triiodothyronine (T3), two hormones that the thyroid gland secretes, may become too much or too little. Once the balance is destroyed, your normal metabolism will be disturbed. Consequently, thyroid disorders such as hyperthyroidism and hypothyroidism will occur. Other possible results include goiter, thyroid nodules and thyroid cancer.
